Cape Verde Islands and Senegambia eastward to Egypt, Abys- 

 sinia, Southern Arabia, to Beluchistan. To the soiuewliat cursory 

 original description, he adds the following particulars. "The 

 sculpture consists of fine, close, subvertical striae, a little bent near 

 the suture, and intersected by several (usually three to six) very 

 narrow smooth spiral hands. These may be obsolete on the last 

 whorl or two, though usually persistent. The whorls are mode- 

 rately convex, the last ascending a trifle to the aperture. Tlie 

 outer lip is somewhat thickened inside, giving the appearance of a 

 low white welt behind it externally. The edge itself is obtuse 

 but not expanded. The coluraellar margin is dilated, thickened, 

 and arches over the very small umbilicus. The species is exces- 

 sively variable, but the typical form is small, specimens measuring 

 as follows : — 



" Length 10, diam. above a])erture 3*8 mm., whorls 83. 



" Length 9, diam. above aperture 3-3 mm., whorls 7i. 



"Length 8, diam. above aperture 3-2 mm., whorls 7|. 



" This small form is common in Arabia and India. The shell is 

 thinner and usually more whitish-corneous, less opaque-white than 

 the lai'ge forms. 



"Shells of the same general type but more robust have been 

 found in both Africa and India, and numerous nominal species 

 have been based upon them. It is quite likely that some of these 

 may be found to be local races worthy of recognition by name."

 aperture." (Benson.)
