We think this more distinct from S. j)ugiiis, than S. pyrulatus. 

 It is more slender, the spire more pyramidal, a larger space being 

 left between the angle and suture of the whorls. The colour is 

 yellowish brown ; the aperture white, the outer lip edged with 

 orange. South Seas. 



36. S. CANARIUM. (pi. viii. f. 69, 70.) 



T. ventricosa, crassa, laevi,antice sulcata; spin! brevi; anfracti- 

 bus rotundato-angulatis; labio interno gibboso ; labio externo ex- 

 panso, crasso, angulato, anticS angustato. 



The colour of this species is a light brown, sometimes tinged 

 with purple, and covered by zigzag lines of light or dark brown ; 

 the aperture is white, or nearly so. A very dark variety is named 

 S. Vanikorensis, in Voy. Astr. Ceylon, Moluccas. 



37. S. ISABELLA, (pi. viii. f. 68, 71.) Lam. 



T. S. canario simillima, sed graciliori ; anfractibus obtuse angu- 

 latis. 



More slender than S. cauarium, the wliorls in a slight degree 

 more angular, the colour generally paler. We are doubtful, how- 

 ever as to its distinctness. A banded variety is named S. taeniatus, 

 in Voy. Astr.

 bonius, Lam. p. 203 



T. ovali, sub-quadrata, laevi ; spira brevi ; anfractibus angulatis, 

 ad angulum tuberculatis, ultimo tuberculorum seriebus tribus ; 

 apertura sub-quadrata ; labio externo postice elevato, medio incras- 

 sato ; sinu antico magno. 



Oval, ventricose, angula ted, smooth ; spire rather short, tuber- 

 culated at the angle of the whorls, with three rows of tubercles on 

 the last whorl, those on the posterior angle largest. General co- 

 lour light brown, with zigzag patches of white on the rows of

39. S. oRANULATus. (pi. ix. f. 100.) Sowerby Zool. Journ. 



T. ovali, sub-quadrata, spiraliter striata ; spira longiuscula ; an- 

 fractibus angulatis, tuberculis coronatis, ultimo seriebus tribus 

 tuberculorum minorum, margine flexuoso; labio interno tenui, 

 expanso ; labio externo crasso, sub-inflexo, postice elevato, interne 

 granulato ; sinu antice magno. 



A species resembling S. fasciatus in shape, with brown and 

 blackish spots arranged in bands on a light ground ; the aperture 

 is white within, yellow inclining to orange on the margins; the 

 inner surface of the outer lip is granulated. 



40. S. THERSiTES. (pi. X. f. 109.) Gray. 



T. ovali, spiraliter striatic ; spira elongata; anfractibus angu- 

 latis, acute tuberculatis, ultimo gibboso, ventricoso, margine 

 crasso, expanso ; apertura sub-quadrata ; labio interno crasso, ex- 

 panso ; postice elevato, calloso ; labio externo crasso, postic6
