I have only had the opportunity of examining the individual from which the figure was taken. It is a male, having the anal valves rather lengthened and obtuse, with a small hook between them, which projects from the last segment of the abdomen. This circumstance proves the error of Cramer, in having mistaken the sexes of this species, both of which he seems to have figured. That which I apprehend is the female (Cramer, pl. 378, fig. F. G.) I have not myself seen. The blue-green on the upper surface of the wings is very resplendent and changeable, and the palpi and thorax beneath are covered with numerous whitish spots. On the under side of the inferior wings, near their base, is a paler band, rayed with the nerves, and in some lights shining with a pale silvery reflection. Mr. Smeathman sent this species from Sierra Leone, in Africa, to Mr. Drury. The locality, therefore, of India, given by Linnaeus and Fabricius, must be incorrect. * * * * * Pl. 126 [Illustration] CONUS vitulinus, _var._ _Orange Fox Cone_,_Brown-tipp'd variety._ * * * * * GENERIC CHARACTER.--See Pl. 65. * * * * * SPECIFIC CHARACTER. _C. testa fulva seu fusca, fasciis 2 interruptis ornata; spirae brevis, levatae, conicae, maculatae anfractibus concavis, subgranose striatis; basi granosa, alba._ _Var. testa flavescente, fasciis obscuris, subalbidis ornata; basi rufa.

Shell yellowish, with obscure whitish bands; the base rufous. * * * * * I received this very uncommon shell from the Island of Amboyna; and although in size and colour it is widely different from the usual appearance of _C. vitulinus_, I have no hesitation in considering it as a remarkable variety only of that species. _C. vitulinus_ in general is a small shell. The best representation of it I have seen is given by Knorr; an author not in general very accurate in his figures. It varies considerably in colour, and approaches very near to _C. vulpinus Lam._ from which it principally differs in having an elevated, though short, spire, instead of one nearly flat: the base is granulated, and generally white; _C. vulpinus_ also has the body whorl carinated and thickest round the upper margin, whereas, in _Vitulinus_, it is gently swelled in the middle. M. Lamarck is, I think, mistaken in the synonyms of this shell, which is represented in the _Ency. Meth._ plate 326, fig. 2 and 4.. The shell at fig. 8. appears to me as the granulated variety of _C. vulpinus_.
