90. Strombus australis (n.s.)
Testa ovato-oblonga tuberculata spiraliter sulcata albida fusco-variegata, spira exserta, cauda recurva, labro incrassato posterius lobo digiti-formi termitato intus (roseo ?) sulcato.
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.
91. Pterocera lambis, Lam. Hist. 7 196.
Strombus lambis, Gmel. Syst. Nat. 3508.
Icon. Lister. Conch. t. 866. f. 21. Martini, Conch. 3 t. 87. f. 858, 859.
This shell is very distinct from Strombus camelus of Chemn. 10 t. 155. f. 1478.
92. Bulla australis, Gray, Ann. of Philosophy, 9 n.s. 408.
Icon. --
This species is very distinct from Bulla striata, Lister. Conch. t. 714. f. 72. with which it has been generally confounded; it is of larger size and perfectly smooth.
93. Bulla hyalina (n.s.)
Testa ovata cylindrica imperforata tenuis hyalina albida laevis concentrice subrugosa; apice incrassato.
