SOWERBY : MARINE SHELLS OF SOUTH AFRICA. 3 



Shell elongated, rather solid, white, irregularly tinged 

 with brown ; spire elevated, rather acute, whorls very 

 slightly convex, very obscurely spirally grooved ; last whorl 

 convex, with a brown band, attenuated towards the base ; 

 aperture moderately wide, canal rather short, columella 

 slightly reflexed. 



Not having the operculum, I cannot place this species 

 with certainty, but it appears to be an Euthria., somewhat 

 allied to Hutton's E. bicinda from New Zealand. 



Bullia laevigata Martini. — A broad heavy species.

B. semlusta Reeve. — In form like B. digitalis., but with the 

 lower half of the whorls dark brown.

 than B. achatina, with an angular keel at the top of the

 whorl, and wider mouth than B. achatina.

 A newly described species, smaller than B. achatina, with 

 a much more slender spire, and with the entire surface
