PHILINE. 451 



are from Galway and Shetland, and measure nearly two 

 lines in length. 



Montagu refers the Bulla punctata of Adams (Linn. 

 Trans.) to this species : I believe he was right in doing 

 so. It is probably the Bulltea angustata of Bivona 

 (according to Philippi), and the Scaphander catenatus 

 of Leach's ' Synopsis/ 



tf*. 5je 3. P. ANGULA'TA*, Jeffreys. ft-^k. 



SHELL rhomboidal, depressed, fragile, transparent and glossy: 

 sculpture, numerous rows of very fine spiral striae, composed of 

 oval and almost microscopic dots, and appearing punctate ; 

 the upper part of the body-whorl is angulated or margined by 

 a sharpish keel, between which and the suture is a flattened 

 space marked with 5 of the spiral stria? and sloping towards 

 the spire ; there is also a tendency to angularity in other 

 parts ; edge of the mouth plain or smooth : colour clear white, 

 becoming opaque in dead specimens which have been picked 

 out of shell-sand ; occasionally one or two transparent zones 

 may be seen, as in the variety of P. catena : spire extremely 

 small, slightly prominent : whorls 2-3, conspicuous ; the 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 (but all my specimens are more or less 

 broken in this part) ; 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 depression. L. 0*1. B. 

 0-075. 



HABITAT: Larne, co. Antrim, Hebrides, and Shet- 

 land, in 60-80 f. (J. G. J.) ; Aberdeenshire (Dawson). 

 It is apparently rare. 



The keeled spire will serve to distinguish this from 

 any other species of Philine in the present section.
