DIAPHANA. 285 



curved, minute longitudinal stria?, which are very closely set on the 

 upper edge of the body whorl ; these strire are crossed by a few in- 

 distinct spiral lines, but not so as to niaiie the surface reticulated ; 

 epidermis inconspicuous. Color whitish, with a faint tinge of red- 

 dish-brown near the outer lip, spire small, truncated and flat ; 

 whorls 3, slightly angulated at the top ; the last is disproportion- 

 ately large, and the first or central whorl is oval and intorted ; 

 suture very deep and channelled, mouth expanded, nearly oval, 

 contracted above by the projection of the periphery ; base even 

 and curved, outer lip semicircular ; the upper part is on a level with 

 the spire ; outer corner rounded, inner corner not receding nor in- 

 curved, as in B. obtnsa, (but my solitary specimen is imperfect 

 in this 2)art) ; inner lip forming a whitish film, which is spread over 

 the upper part of the under side, it is folded over the pillar, behind 

 which it forms a narrow umbilical groove ; pillar slight and curved, 

 fold obscure. Length 0*125, breadth O'l inch. (Jeffr.).

Sars thinks that this may be the same as Phlline velutmoides. 

 The soft parts are still unknown. 



Mr. Barlee procured a single specimen by dredging off" Glenelg 

 n Skye ; this is now in my collection. I tried the same ground 

 with jNIr. Norman last year, in the hope of confirming the discovery, 

 but we were unsuccessful. Its nearest ally api)ears to be the Am- 

 jihisphi/ra globosa of Loveu (a Scandinavian species). Our shell, 

 however, is ear-shaped, instead of globosely oval, the spire is pro- 

 2>ortionately broader, the mouth much wider, and the sculpture 

 peculiar, XJ. ghbosus exhibiting only the lines of growth. (Jeffr.).
