8o Quarterly Journal of Coudwlo^^y. 



Shell conoid, ventricose, solid, bluish white, banded and 

 blotched with dark brown; spire rather short, acute; whorls 

 angulated and noduled at the angle, spirally striated above; last 

 whorl almost smooth in the middle, then towards the margin 

 conspicuously striated, grooved at the base; aperture elongated, 

 with a canal at the upper part, running up the spire; columella 

 furnished with a thickened white enamel, \\hich is faintly ridged; 

 outer lip emarginated; interior ridged. 



Bab. Hongkong ( Cnthill). 



The characters of this species are much the same as those of 

 S. septunus (Duclos), of which Mr. Cuthill has sent me several 

 specimens from the same locality; but the form is very different, 

 the latter being a narrow shell of the form of S. succindiis (Linn), 

 which is found in Ceylon.

Shell fusiform, reddish brown, variegated with bluish white and 



dark brown, thin, transparent; spire acuminated; whorls nine in 



number, flatly convex, smooth, strongly ribbed longitudinally; the 



ribs on the last whorl towards the margin tuberculated in the middle, 



transversely ribbed at the base; aperture oblong, interior blue, ribbed; 



columella wrinkled, covered Avith a transparent, shining enamel; 



canal short, deep, recurved ; outer lip thickened and expanded at 



the upper part, and with a broad deep sinus in the middle. 



Hab. Upper California. 



A very remarkable little shell, almost generically distinct from 

 any hitherto known species; I think, however, it truly belongs to 

 the section Anachis (H. & A. Adams). The sinus is almost like 

 that of Plcurotoma, only it is in the middle of the lip.
