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 Bullcea angustata of Bivona 

 (according to Philippi)^ and the Scaphander catenatiis 

 of Leach-'s ^ Synopsis.^ 



3. P. angula'ta*, Jeffreys. 



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 : sjnre extremely 



small, slightly prominent : wliorls 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 Iq) 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.
