to pale brown, mottled with darker brown. The striae on the inne/ 

 part of the aperture are in some specimens nearly obsolete. 



31. S. bulbulus (pi. ix. f. 81, 82, 83.) Nobis, Zool. Proc. 1842. 

 T. S. terebellato simillima sed magis ventricosa, anfractu penul- 



timogibboso; labio interno validiore; labio externo valide striato, 

 postice spiree partem decurrente. 



More ventricose than S. Terebellatus, with the penultimate whorl 

 gibbous, the inner lip thicker, the outer lip striated to its edge and 

 posteriorly elevated on the last whorl of the spire. Fig. 84. is from 

 a specimen in Mr. Stainforth's collection where it has existed for 

 some time without any history, and we think it may be a variety of 

 t his species which has been brought by Mr. Cuming from the Philip- 

 pine Islands. 



32. S. glabratus. (pi. viii. f. 66, 67.) Nobis. 



T. sub- pyramidali, nitida; apertura. ovali, bicanaliculata ; colu- 

 mella truncata ; labio externo crasso reflexo, antice sub-emarginato ; 

 operculo ovali ; anfractu ultimo ad dorsum prope suturam plicato. 



This singular shell, having the general form of a Nassa, never- 

 theless has a slight emargination in the outer lip, and is considered 

 by experienced conchologists as being allied to the family, at least, 

 of Strombida?, although differing from the present genus in being 

 covered by a glassy enamel. We place it here to remain till some 

 author shall undertake to erect it into a new genus, and define its 

 characters. The colour is pale straw, with a reddish tinge on the 

 back, and a grey line under the suture of the spire. 



33. S. pugilis. (pi. viii. f. 74.) Lin. Syst. Nat. 1209. 



T. turbinata, ventricosa ; spirabrevi,spiraliter sulcata ; anfracti- 

 bus angulatis ad angulum tuberculis magnis acutis coronatis ; aper- 

 tura angusta, labio interno tenui expanso, externo brevi, interne 

 striato, postice emarginato, lobato, antice truncato ; sinu magno ; 

 operculo parvo, pyriformi. 



This well-known shell is of a rich vermilion colour, tinted with 

 yellow and at the anterior termination with purple. It is lobed at 

 the angle of the outer lip and truncated at the anterior extremity.

34. S. pyrulatus, (pi. viii. f. 72, 75.) Lam. 



T. S. pugili simili sed magis elongata, spirss anfractibus vix tu- 

 berculatis valide striatis. 



More elongated than S. pugilis, with the whoils of the spire 

 scarcely tuberculated. The colour is dark brown, tinged with 

 purple at the mouth. The variety, f. 72, is white with zigzag lines 

 of brown. We think, however, that both varieties may belong to 

 S. pugilis, the difference not being greater than between acknow- 

 ledged varieties of other species. 



35. S. gracilior (pi. viii. f. 73,) Sow. App. Tank. Cat. 



" T. ovato-oblonga, apice acuminato-pyramidali, ad basin trans- 

 verse striata, pallid e aurantiaca; anfractibus superne nodulosis ; 

 pabio interno tenui expanso, externe dilatato intfis transverse 

 leviter sulcato."
