This heading makes no mention of the columellar plication of the shell so named in the 'Systema,' and confirms my surmise of their distinctiveness. The name livida was not originally attached to the description, but had been added (together with "obsoletis") by Linnæus, from a mistaken identification.
There has evidently been some error in the comparison with Voluta Caffra. I suspect that Conus bullatus was meant, as the contrasting characters answer admirably. "Differt a B. pallida et livida, quod testa solida—anfractus spiræ canaliculati". This passage shows that "fragilis et spiræ anfractus obtusæ" referred to livida, not to Caffra.
VOLUTA.
Testa oblonga, subconvexa, basi emarginata, replicata in canalem rectum. Columella plicata oblique. Labio integro.
The genus appears to comprehend precisely the same members as in the published edition. They were arranged in sections exactly corresponding with the Lamarckian genera of Oliva, Voluta, Mitra, and Marginella.
V. porphyria. V. spira basi obliterata, labio medio retuso.
Linnæus spoilt his excellent earlier description by his attempted emendations. The interpolated "Faux sæpius rufescens" (misprinted virescens), and the reference to Gualtieri's figure O. (O. erythrostoma), formed no part of the original version.
The "Varictas fere sola est V. Olivæ" was an afterthought.
V. Oliva. V. spiræ basi reflexa.
The synonyms were thus distributed. To var a, Rumph. t. 39. f. 2, and Gualt. t. 23. f. B; to var. g, Rumph. t. 39. f. 3; to var. e, Arg. t. 16. f. R; to var. d ("Cæsius atro-undatus," not "Fusco undulatus" as printed), Rumph. t. 39. f. 4. The expressions "ponderosa" and "magis sulcatum" were not in the original.
