ent. The specimens from Stations 186 and 187 are quite young 

 shells, Imt are, I have no doubt, this species. From Honolulu, 40 

 fathoms, there is a specimen of Atys probably belonging to this 

 >perie-. but in too bad condition for identification with any cer- 

 tainty.

Shell elon^ately oval, rather thin, shining, white, attenuated and 

 umbilicated at both ends, longitudinally obliquely plicated, strongly 

 transversely striated at each end, the centre or intermediate space

 ened within, nearly straight posteriorly, slightly twisted and pro- 

 duced : inner lip at the anterior end forming a thin callous ridge at 

 the side of the umbilicus, slightly reflected, and ending in a denti-

.1. rlieirrti BRA/.., P. L. S. N. S. W. ii, p. 86, 1877. 



This species i.> like a miniature Aty* elongctia. Some specimens 

 have an opaque appearance at the back of the aperture, others very 

 thin and transparent (Braz.).
