400 TELLINID^E. 



with the usual short dusky streaks ; posterior ridge more de- 

 veloped and conspicuous. 



Habitat : Local, but generally diffused, from low- 

 water mark at spring-tides to a few fathoms, in sand. I 

 will mention a few of the localities : Cornwall, Devon, 

 Dorset, Channel Isles, Scarborough, Northumberland 

 and Durham, Pembrokeshire, Pwllheli (M' Andrew), 

 south and west of Ireland, Stranraer in Wigtonshire 

 (Bedford), west of Scotland, Firth of Forth (Laskey, 

 Brown, and Collins), Moray Firth (Dawson). Var. 1. 

 Exmouth (Clark); Kenmare River (J. G. J.). Var. 2. 

 Bantry Bay (Humphreys). This species has been found 

 in a fossil state at Belfast by Mr. Grainger, and in the 

 Coralline Crag by Mr. Searles Wood. Abroad it in- 

 habits the Scandinavian sea from Finmark to Bohus- 

 lan, and southwards the coast-line from the North of 

 France to the Canaries, as well as the European and 

 African shores of the Mediterranean as far as Sicily and 

 the iEgean, at depths varying from 7 to 10 fathoms. 

 Sicilian tertiaries (Philippi). 



At Kenmare this kind is eaten, as well as Venus ver- 

 rucosa ; and heaps of their shells may be seen about the 

 huts of the peasantry. Twisted distortions now and 

 then occur. My largest specimen is one and a half inch 

 long by two and a half inches broad ; but some collected 

 by Lilljeborg in Upper Norway are of still greater di- 

 mensions. 



Miiller apparently considered this the Tellina radiata 

 of Linne; and the descriptions in the i Fauna Suecica' 

 and ' Systema Naturae 3 are not unsuitable ; but the 

 more detailed particulars given in the ' Mus. Ulr. Reg/ 

 mention a character which our shell does not possess, 

 viz. lateral or marginal teeth. Possibly the angular 

 points of the hinge-plate were meant. The words arc.
