231. Columbella (Atilia) conspersa, Gask. 



IjOC. Cargados Carajos : Station B 8, 35 fathoms. 



C. puella, Sovvb., is, I think, rightly conjectured by Tryon (Man. Conch, v. p. 145) 

 to be identical, though the typical forms are larger and more elaborately sculptured. 



A specimen with the apex badly broken, from Coetivy, was at first set aside as being 

 j)erhaps undescriljed, but careful examination with large series of conspersa from the 

 Persian Gulf, &c., prompt one to the conclusion that it may be identical. It is a 

 handsome form, shining, smooth, yellow-brown, attenuate towards the apex, the last 

 whorl well shouldered at the periphery, the whole surface closely painted with straight 

 close longitudinal darker lines.
