410 TELLIN1D.E. 



present species occurs in the Coralline Crag. It does 

 not appear now to inhabit any part of the European sea 

 so far north as the Suffolk coast, its recent distribution 

 being entirely southern. De Gerville has recorded it 

 from the north of France, Cailliaud from the Departe- 

 ment of Loire Inferieure, M 'Andrew from the coasts of 

 Portugal and Gibraltar in 8-30 fathoms, Payraudeau 

 and Requien from Corsica, M f Andrew and Weinkauff 

 from Algiers, Scacchi and others from Sicily, and 

 Forbes from the ^Egean. According to Philippi it is 

 a fossil of the South-Italian newer tertiaries. 



Linne did not notice this elegant shell, although he 

 might have seen a good representation of it in Lister's 

 ' Historia Conchyliorum ' (A. pi. 385. f. 232, "I. Garn- 

 sey "). Besides being local, and therefore comparatively 

 scarce, it may be readily known from either of the two 

 foregoing species by being natter, more oblong, and not 

 so inequilateral, and by the surface being more polished 

 and lustrous, and never striated; the single white ray 

 is also a peculiar feature; the inside margin appears 

 smooth, and the crenulations are only to be seen under 

 a tolerably strong magnifier ; and the lateral teeth are 

 much less distinct. 



It is the Tellina variegata @ of Gmelin, and probably 

 his T. vinacea from Buonanni (' ( Habitat in mari britan- 

 nico et balthico " !), D. complanata of Montagu, D. long a 

 of Bronn, and D. glabra of Searles Wood. 



D. Laskeyi (Tellina Laskeyi, Montagu) is not unlike 

 the last species in shape, but is much smaller, the 

 streaks on each side of the beak are more conspicuous, 

 and the lateral teeth are more blunt and obscure. I 

 have one of the original specimens (a single valve), 

 owing to the kindness of my late friend Mr. Dillwyn, 

 who received it from Colonel Montagu. It is supposed
