"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.
