1903. J MOLLUSKS FROM THE P£JIS1A>, SULF. 347 



Highly sculptured, the angle minute, the whorls being 3^-, the 

 upper small, the body-whorl larger in proportion, four-keeled, the 

 carina acute. With the aid of a lens the surface is seen to be 

 longitudinally extremely shagreened or striate. The peristome is 

 continuous, six-angled externally, aperture round. The operculum 

 is present, horny and multispiral. The nearest ally, C. trl- 

 carinatum Smith, from W. Africa, we have compared with our 

 species. There is some affinity, but, as its name implies, that 

 species is but three-angled and is likewise radiately lirate. 



Cyclostrema solariellum Melv. 



P.G. Fao. Bushire. Gulf of Oman, lat. 26° 23' N., 

 long. 54° 55' E. 25 fathoms, mud ; with C. oingulatum but much 

 more frequent. 



1. Karachi, fine and large. Bombay (Abercrombie), only worn 

 examples, from one of which the type was described in 1893. 



This species has the aspect of a small Torinia, and by some 

 malacologists would perhaps be relegated to that, genus. We 

 await examination of the soft parts and operculum before deciding.

 loose stones. Always local, the range is wide, extending from
