28. Monodonta conica (n.s.)
Testa conica, acuta, imperforata, spiraliter striflto-costata, rufa; costis subtuberculatis, albo-nigro-articulatis; apertura sulcata.
Inhab. -- Mus. Brit.
Shell conical, axis longer than the diameter, the whorl flattened with six spiral raised substriae, which are transversely divided into blackish purple beads with white interspaces, the apex rather acute; the base, rather convex, axis imperforated; the aperture subquadrangular, inside furrowed; the base of the columella lip with a prominent tooth and distinct groove behind it, the upper part rugose; axis eight-twelfths, diameter six-twelfths of an inch. This shell does not appear to be uncommon on the coast of Australia.
29. Monodonta uranulata (n.s.)
Testa depresso-conica, umbilicata, purpurea, albomarmorata, spiraliter papillata; papillis quadri-seriatis, umbilico laevi; infima facie papillata, apertura sulcata.
Inhab. Mus. Brit.
Shell rather depressed, conical, purple variegated with white, generally concentrically wrinkled, and ornamented with granulated spiral ribs, the ribs of the upper part of the last, and of all the other whorls rather distant, and forming four series; those of the under part rather closer, and smaller. The axis unbilicated, smooth, the aperture roundish, the outer lips furrowed, the columella lip smooth with a groove at its base, axis four-twelfths, diameter five-twelfths of an inch.
30. Monodonta denticulata (n.s.)
Testa depresso-conica, umbilicata, rufa, nigro punctata, spiraliter sulcata, subgranulata, umbilico extus crenato.
Inhab. -- Mus. Brit.
Shell depressed, conical, pale reddish, ornamented with rows of white and brown spots, spirally grooved, ribs slightly granulated; the sutures distinct, impressed, the lower part of the last whorl nearly smooth, the umbilicus white, smooth inside, the edge furnished with a series of granules. The mouth subquadrangular, outer lip crenulated at the edge, the columella lip smooth, with a large tooth at the inside, and a little roughness on the outer side; axis three-tenths, diameter five-twelfths of an inch.

Testa ovato-conica imperforata ulbido-purpurea rudis crassa, labro duplicato, extus albido viridi, intus subsulcato, albo.
Inhab. -- Mus. Brit.
Shell ovate, conical, imperfurated, rough, pearly, concentrically striated, whitish-brown; when worn or where eroded, purple; the whorls convex, suture distinct, sometimes occupying an impressed line on the lower whorl; the base rather convex, the aperture roundish, the axis (imperforate) covered with a white callus, which leaves a slight concavity over its end; the outer lip of three colours, the outer part purple or green and white, the middle pearly, and the inner opaque, white, and furrowed; the surface of the lower part of the last whorl is frequently worn away just opposite the mouth, so as to leave a purple spot.
33. Rissoa clathrata (n.s.)
Testa subglobosa, subimperforata, alba, solida, spiraliter et concentrice costata; apertura suborbiculari, sutura impressa.
Shell nearly globular, spire conical, upper whorls with three, lower with seven distinct, large, rather separate, much raised, spiral ribs, and numerous acute transverse ribs, which form an acute tubercle where it crosses the spiral ridges, the suture deeply impressed, very distinct, the aperture nearly orbicular, the outer lip denticulated on its outer edge, inner lip smooth, column without any perforation, only a slight linear cavity behind the inner lip, axis and diameter each one-sixth of an inch.
This shell is allied to Littorina muricata (Turbo muricata, Lin.) in its general form and the shape of its umbilicus, but is white and ribbed like Rissoa cimex (Turbo cimex, Lin.) R. calathriscus, the Turbo calathriscus of Montague.
34. Solarium biangulatum (n.s.)
Testa orbiculato-conica subdepressa albida spiraliter sub-striata rufo variegata, anfractibus biangulatis supra planis infra convexis, umbilico pervio edentulo.
Shell orbicular conical; spire rather depressed; whorls five spirally striated; upper part flattened, expanded, white with numerous diverging red cross lines; centre flat, nearly at right angles with the upper edge, white, with a convex thread-like rib round its base, which is distantly articulated; base of the whorls convex, red, punctured and variegated with white; axis conical, concave, white, smooth at the commencement; aperture subquadrangular; inside pearly, inner lip with an obscure tooth at the end of the umbilicus; axis one-fourth, diameter one-third, of an inch.

Testa minuta oblique conica tenuis pellucida linea albida opaca et fasciis coccineis ornata, anfractibus valde convexis.
Shell minute, obliquely conical, thin, pellucid, variegated with spiral opaque white intercepted striae and several transverse scarlet bands formed of oblique lines; axis, imperforated, one-sixth, diameter one-eighth, of an inch.
This shell is somewhat like P. pullus, Turbo pullus of Montague, but the whorls are more convex, and it is rather differently marked.

Testa ovata, conica fulva rudis spiraliter striata sulcata, spira acuta, fauce livida.
Shell ovate, conical, fulvous-brown, rough, with numerous impressed spiral lines; the spire acute, the whorls rather convex, last slightly angular, the columella lip purplish-brown; axis solid, with a lunate concavity behind the usual situation of the umbilicus.
48. Littorina unifasciata (n.s.)
Testa ovato-conica imperforata purpureo-albida laevigata, anfractibus convexis ultimo subangulato, apertura purpurea unifasciata.
Icon. --
Shell ovate conical, nearly smooth, with only a few concentric ridges, and distant, scarcely impressed, very narrow, grooves; white or purplish-white outside; the whorls rather convex, last one slightly angular in front; mouth ovate; throat purple or purplish-black with a distinct broad white spiral band just below the slight external keel; inner lip purple with a deep concavity behind it; spire acute half the length of the shell; axis 8/12, diameter 6/12, of an inch.
This shell has somewhat the shape of Littorina zigzag, the Trochus zigzag of Montague, but is all of one colour externally and has a much shorter spire.

Testa ovato-conica superne transverse plicata basi spiraliter striata purpureo-livida obscure castaneo bifasciata, anfractibus convexiusculis, sutura linea alba notata, labro extus marginato intus sulcato.
Icon. --
Shell ovate conical, livid purplish-white, with one or two central, obscure brown, bands; upper whorls bluntly transversely plaited, the rest smooth, livid, except at the front part of the last, just over the groove, where it is spirally striated; the suture distinct (not channelled) marked by a white line; the inner lip distinct, raised, the outer thickened on the outer side, edge sharp, inside grooved; the throat fulvous-brown; axis one inch, diameter half an inch.
This shell belongs to the group of Nassa, but will perhaps form a distinct genus intermediate between it and Columbella, characterized by the narrow form of the mouth. It is most nearly allied to N. olivacea, n. (Bucc. olivaceum, Lam.) and N. canaliculata, n. (Bucc. canaliculatum, Lam.)
58. Clavatula striata (n.s.)
Testa ovato-lanceolata turrita albida regulariter spiraliter sulcato-striata transverse et interrupte costata, anfractuum margine superiore angulato subnodoso, cauda brevi, fauce sulcata.
Icon. --
Shell ovate turreted, whitish-brown, with eleven or twelve longitudinal interrupted ribs forming long tubercles on the centre of the whorls; the whorls with distant impressed spiral lines near the suture, with a rather flattened slightly nodulose band; the mouth rather more than one-third the length of the shell; outer lip thin inside, grooved; tail short, with a linear depression on its columella side; axis ten-twelfths, diameter four-twelfths of an inch.
59. Cassis achatina, var. Lam. Hist. 7 226.
A worn specimen, apparently a variety of this species. It is entirely smooth, polished, and has the last whorl near the spire slightly concave, edged with a scarcely raised rather nodulous line, the outer lip is very thick, grooved on its inner edge, and the columella is distinctly plaited.
It may perhaps prove to be a new kind; but the species of this genus are so exceedingly apt to vary, that I do not wish to increase the number of the already too much extended lists of Lamarck and others.

Lamarck never having seen this shell has described it on the authority of Chemnitz, whose figure agrees very well with the shell before me; excepting that the spots round the suture form nearly a continual band at a little distance from it; the outer lip is smooth and thin; the inside dull livid brown; the axis is fourteen-twelfths, the diameter seven-twelfths, of an inch.

Icon. -- ?
Shell ovate oblong, spiral, white, spotted and lined with pale, fulvous-brown; the spire exserted, conical, half as long as the shell; the whorls longitudinally ribbed with one more prominent than the rest, the one nearest the suture being acute and tuberculated; the canal recurved; the outer lip thickened, ending in a projecting lobe behind, and edged with two or three blunt tubercles; the throat rose-coloured, furrowed; the inner lip much thickened.
This shell is one of the five species which have been confounded with Strombus auris dianae; it is most like S. zelandiae, n. Chemn. 10 t. 156. f. 1485, 1486, in form and throat, but has the sculpture of S. adusta, n. Chemn. 10 t. 156. f. 1487, 1488; this last Lamarck considers as the true S. auris dianae, whilst Linnaeus unquestionably describes the shell figured by Martini, 7 t. 84. f. 840, and by Seba, 3 t, 61. f. 1, 2, which I have named S. lamarckii, from having considered it to be the young of a new species; it is figured by Martini, 7 t. 84. f. 338, 339, and by Seba, 3 t. 61. f. 5, 6, and is very nearly allied to S. bituberculatus of Lamarck.

This shell is very nearly allied to Pileopis, but the animal is evidently not brachiopodous. It does not form (or at least not always) a shelly support, but corrodes the surface of the shell to which it is attached, so as to form a more flat attachment, and to leave a lunate convex rib instead of the lunate muscular impression which is observed on those specimens or individuals which have a shelly base.

When this shell is young, or when the older specimens have lived in deep water, where their surface has not been broken by the shingle, or corroded, or covered with coralloid incrustations, they are regularly radiately ribbed; the ribs are covered with narrow intermediate grooves, marked with a black spot on the internal edge of the shell, which is permanent through all the variations of the outer surface. The inside is pale purplish-brown, with a yellowish-white muscular impression. In the older specimens the central disk is often of a pure opaque-white, and the muscular impressions round the inner edge of the shell are both pellucid brownish-white; length four inches, breadth three, height two inches.
This shell is abundant on the rocky shores of King George the Third's Sound.
In the collection there is a worn specimen of another species of this genus; but from its bad state, and from the very great confusion in which the various species of Patella are involved, I do not venture to describe it as a new shell, although there has not been any hitherto described to which, in its present state, it can with any certainty be referred. It is conical, convex, with twenty-four or twenty-five distinct convex ribs alternately increasing in size; the grooves between the ribs are broad, with irregular, concentric, black-brown, raised lines, which appear to be caused by the wearing away of the other part of the dark outer coat; the inside is white with a brown disk, and the edge sinuated and furnished with grooves under the larger ribs.
103. Haliotis roei (n.s.)
Testa subrotunda convexiuscula rugosa et plicata spiraliter sulcata intus argenteo et rubro margaritacea, spira prominula.
Icon. --
Shell roundish, rather convex; the outside reddish or brownish, regular; closely but unequally spiral, ribbed, and irregularly and roughly concentrically striated and plaited; the row of perforations is rather prominent, and pierced with six or seven moderate-sized, slightly tubular, holes; the inside is iridescent, pearly, rather wavy, and exhibits two distinct whorls; the columella lip is short and flattened, outer lip rounded; the spire is convex, rather prominent, placed about one-third of the breadth of the shell from the outer lip, and consists of three whorls, which very rapidly enlarge.
This distinct shell, at the desire of Captain King, has been named after Lieutenant J.S. Roe, the assistant-surveyor of the expedition.
It is most nearly allied to H. australis, Chemn. 10 t. 166. f. 1604, but differs from it in being rounder and more distinctly ribbed.
104. Haliotis cunninghamii (n.s.)
Testa ovato-rotundata tenuis depressa rugoso-subplicata spiraliter striata intus argenteo et rubro margaritacea, spira prominula, foraminibus parvis.
Icon. --
Shell roundish-ovate, thin, depressed; the outer surface very slightly concentrically plaited and rough, and finely, regularly, spirally, striated; the row of perforations slightly elevated, pierced with eight or nine small slightly-tubular holes; the spire rather prominent, apex placed about one-fourth of the breadth of the shell from the sutural angle on the outer lip, consisting of four whorls which rapidly enlarge; the inside expanded out, disk nearly flat exhibiting one distinct whorl; the columella lip narrow, rather long, flattened; the outer lip thin, truncated; the nick of the imperfect perforation placed about one-third the length of the outer lip from the end of the columella lip: length six inches, breadth five.
This shell, at the wish of Captain King, has been named after Mr. Allan Cunningham, the botanical collector of the voyage.
This species, although nearly allied to Haliotis midae, is quite distinct from it.
105. Haliotis squamosa (n.s.)
Testa ovato-oblonga convexa rugoso-plicata aurantio-rubens spiraliter costata, costis tuberculato-muncatis, fauce margaritacea, spira retusa.
Icon.
Shell ovate-oblong, convex, externally transversely rugose, plaited and spirally ribbed; the ribs concentrically striated and furnished with numerous raised scale-like tubercles; the row of perforations scarcely round contains ten or twelve rather large holes; the spire slightly raised, very near the edge, consisting of two or three very rapidly-enlarging whorls; the inside concave, showing the external ribs, reddish pearly; the columella lip narrow, depressed, bent; the outer lip thin, strait, or cut out; the imperfect perforation about one-fifth the length of the outer lip from the end of the columella lip; length two, breadth one inch and a quarter.
This species is very distinct on account of its long form, and curved lower face, as well as its outer surface.
