CONUS.

Testa oblonga, cylindrica, deorsum attenuata. Apertura longitudinalis. Labium edentulum. Os non reflexum. Columella integra.

This most natural genus had the precise limits ordinarily assigned to it.

C. marmoreus. C. conicus fuscus, maculis ovatis albis.

"Bonan. 3. f. 123" was an additional synonym; the "versus basin transverse striata," and "subtruncata, apice prominulo," with the account of the variety, were not found in the MS.

C. imperialis. C. pictus fasciis flavis cingulisque linearibus albo fuscoque articulatis.

The "obconica" was simply "conica"; there was no description of the spire.

C. literatus. C. conicus albus punctis fuscis.

The spire was not described: the reference to d'Argenville was I, not Q.

C. virgo. C. striis convexis lævibus, basi cærulescente.

"Longa" was originally "magna": the erroneous reference to Gualtieri was not inserted.

C. capitaneus. C. conicus, basi fusca, spiræ anfractibus adscendentibus.

At least two species were confused; but, from the heading, it is clear that C. generalis, rather than C. capitaneus, was the typical form: the latter was the variety g.

The V in the reference to Rumphius was a misprint for the written Y: "Gualt. t. 20. f. G." and "Pet. Gaz. t. 27. f. O." were additional synonyms. "Notata lituris undatis fuscis" was not in the manuscript.

C. princeps. C. flavus, lineis fusco-purpureis longitudinalibus ramosis.

"Sub" preceded "convexa."

C. Ammiralis. C. basi punctato-scaber.

After "summus" was written "cingulo albo"; after "ordinarius," "cingulo nullo"; Seba was not quoted; "pruniformis" was the earlier reading for "conico-convexa, pyriformis." The variety a. was described as "circumdata lineis numerosis albis nigro articulatis, quarum quæ cylindrum distinguit a spira latior maculis albis nigrisque majoribus alternantibus." The variety g. was not originally present in the catalogue, but was interpolated by Linnæus. "Hæc pretiosissima ut vendita fuerit 500 florenis" was the final remark.

C. nobilis. C. subcylindricus lævis glaber, spira acuta argute canaliculata.

"Cacumen" was a misprint for the written "acumen."

C. Genuanus. C. pictus cingulis linearibus albo fuscoque articulatis.

A strange confusion took place between the details of C. senator and C. Genuanus. The published description belonged to the former, the synonym the latter, and should have preceded the following brief description:

"Testa conica, pallida, glauca, oblongiuscula. Lineæ 19 transversæ fusco-nigræ s. purpurascentes albo interruptæ, alternæ sæpe angustiores. Spira subconica, obtusa."

C. glaucus. C. emarginatus, basi striatus, spiræ inermis anfractibus convexis.

C. monachus. C. gibbus acutus, fusco-cærulescente nebulosus, basi striatus.

Bonanni was not quoted in the written copy.

C. minimus. C. cinerascens, punctis oblongis cinctus.

The original description has been much altered by Linnæus. It ran as follows: "Testa ovata, glauco-cinerea, gibba, striæ transversales plus 30 punctis fuscis oblongis. Spira convexa, alba, maculis fuscis magnis transversis." The cited figure does not even suit these meagre characteristics, which might have been equally applied to C. glaucus.

C. rusticus. C. ovatus, basi rugoso-scaber, spira conica convexa.

The variety was not noticed, and d'Argenville was not quoted in the original catalogue. "Flavo et glauco" should have been "flavo aut glauco," as written.

C. mercator. C. ovatus, albus fasciis reticulatis flavis.

C. betulinus. C. subemarginatus, basi rugosus, spira planiuscula mucronata.

Seba was not cited.

C. figulinus. C. emarginatus, basi rugosa, spira convexa acuta.

An additional synonym, "Rump. t. 31 (error for 33, there being no number 1 in that plate) f. 1," was indicated.

C. Ebræus. C. ovatus albus fasciis nigris ex maculis transversis.

"Pet. Gaz. t. 99. f. 12." was quoted.

C. stercus-muscarum. C. emarginatus, basi striatus, spiræ anfractibus canaliculatis.

Of the two species confounded under this designation the C. arenarius appeared as a variety in the manuscript. Of the typical form "Spira lævi," "Pet. Gaz. t. 75. f. 1," and "Rumph. Mus. t. 33. f. Z," were cited as illustrations; the other synonyms were ascribed to "Var. α. coronatus spinis obtusis." The colouring was not mentioned.

C. varius. C. scabro-coronatus, elongatus, spira coronata acuta.

C. granulatus. C. scaber inermis, striis lævibus.

The original size indicated was "magnitudine coryli."

C. magus. C. subcylindricus, fasciis longitudinalibus albo punctatis.

The erroneous figure of d'Argenville was not referred to; and the 32, Q (as in the 'Systema'), not 34, A, of Rumphius was quoted as illustrative. The final remark had been interpolated by Linnæus.

C. striatus. C. ovato-oblongus gibbus nebulosus, striis tenuissimis parallelis fuscis.

The "Cæterum testa minus ante convoluta est," is a press addition. "Pet. Gaz. t. 98. f. 9." was correctly cited.

C. textile. C. pictus venis reticulatis luteis, maculis luteis fuscisque.

The intended name (C. drador) was an amusing specimen of conchological Latin: it was of course borrowed from d'Argenville's appellation of "Drap d'or." "Columella ad postica quasi replicata est" was added in the printing; the "luteo" was originally "albo"; the "subconica" was "anfractibus subconicis"; and there was no mention of a variety.

C. aulicus. C. pictus venis reticulatis fasciisque longitudinalibus interruptis fuscis.

"Columella postice replicata est," and the objectionable "obovato-sub," were not in the copy. No figures were cited in the original catalogue.

C. spectrum. C. cærulescens, flavo-nebulosus, punctis striisque alboluteis.

The original description did not comprise those characteristics which are so much at variance with the essentials of the C. spectrum of authors. The following passages were omitted: "gibba, minus arcte convoluta" (this replaced "conica"), "Columella postice striata et replicata. Intus testa sub-cærulescens," "mucrone cingulis granulato."

C. bullatus. C. flavus, albo nebulosus.

The account of the variety, and the "vix tuberculata," were absent from the manuscript.

C. geographus. C. oblongus gibbus coronatus.

The Rumphian name was the one attached to this species in the written copy.

C. terebellum. C. scaber inermis, striis tuberculatis.

The synonyms attached to the published details were "Gualt. Test. t. 25. f. L.—Arg. Conch. t. 16. f. P.—Rumph. t. 33. f. EE." Now these harmonize with both the heading and the description, and clearly indicate the C. Nussatella of the 'Systema'!

The details attached to the published synonyms (which latter belonged to the C. terebellum of the 'Systema,' and to which were joined "Gualt. t. 23. f. O.—"Bonan. 3. f. 57.—Pet. Amb. t. 13. f. 24,") ran as follows:

"Testa cylindracea, glabra, antice angustior, desinens in spiram attenuatam, anfractibus 3. Basis truncata, tennis. Columella non torta, sed involuta. Color pallidus."
