18 PHILINE. 



outer edge of each is keeled or ridged ; suture deep and channelled ; 

 mouth squarish, remarkably wide and large, nearly truncated at the 

 base ; outer lip forming an obtuse angle at the junction of the front 

 and base ; the top is higher than the spire, and it projects outwards; 

 inner corner deeply and widely cloven, so as to make the disjunction 

 of the outer whorl from the next very conspicuous ; inner lip forming 

 a narrow but thick ledge or fold, behind which is a slight depres- 

 sion. (Je/r.). Alt. 2-5, diam. 1'9 mill. 



Larne Co., Antrim, Hebrides and Shetland, 60-80 fms. ; Aber- 

 deenshire.

The keeled spire will serve to distinguish this from any other 

 species of Philine having conspicuous spire and chain-like sculpture.

Shell oblong, convex, very thin and fragile, nearly transparent, 

 and of a polished luster ; sculpture, none on the body-whorl ; but 

 the spire has two keels or ridges, one at the outer edge of each whorl, 

 and the other in the middle, giving this part an angulated appear- 

 ance, color clear-white, becoming opaque in dead specimens ; spire 

 flattened, placed somewhat obliquely; it is quite exposed and 

 occupies the top of the shell; whorls 2J, irregularly twisted, but dis- 

 tinct ; suture deep and excavated ; mouth oval, truncated above, 

 wide and rounded below, its area equals about two-thirds of the 

 under surface ; outer lip expanded, squarish at the top, and gently 

 curved in the middle; it is level with the spire, viewed mouth 

 downward, and is below it, viewed mouth upwards ; outer corner 

 angular and projecting ; inner corner considerably receding and 

 acute-angled ; inner lip forming a broad glaze on the upper part, 

 and reflected on the pillar; there is no umbilical groove or de- 

 pression. (Jejfr.). 



Alt. 1-8 mill.

Jeffreys' figures would hardly justify the union of his species with 

 that of Sars, but the description leaves little doubt of their identity.
