"The two specimens of this species at hand are probably 

 not full-grown, as a faint angulation at the periphery of the 

 body-whorl suggests this opinion. In that case the number 

 of whorls and the proportion of the aperture to the total 

 length may hereafter require modification. 8. involute 

 Gould, is similarly colored, but is a larger and thicker shell. ' ' 

 (E. A. Smith). 



The specimens collected by Stuhlmann are a little larger. 

 The dark brown, somewhat streaked coloration is character- 

 istic of this species and 8. elegans. Perhaps they would be 

 more correctly placed in Homorus.

Shell club-shaped-turrited, very weakly striate, glossy, pale 

 yellowish. Whorls 9%, somewhat convex, the first compara- 

 tively small, rather globose, the second and third of nearly 

 equal size, the following whorls slowly increasing in breath, 

 with rather deep, somewhat crenulate suture; the last whorl 

 scarcely convex above, rounded beneath. Aperture acutely 

 ovate, rather oblique ; outer lip thin, unexpanded ; basal mar- 

 gin shortly rounded, 'columellar margin weakly arcuate, some 

 what thickened, whitish. Length 26^, diam. 8, aperture 

 8x4 mm. (Marts.)

To be recognized by the comparatively wide contour and 

 glossy-smooth surface; in shape like Homorus mamboiensis 

 but decidedly smaller.
