TELLINA. 307 



is usually curved upwards. Mr. Clark describes the ar- 

 rangements of the branchial and labial palps to be similar 

 to those of T. tenuis, except that the latter are broader. 

 The foot is white, flat, linguiform, rather pointed, bent at 

 the base, and of moderate dimensions. The colour of the 

 animal is yellowish, tinged slightly, especially the branchiae 

 with reddish-brown. 



" This species,"" observes Montagu, " is found common 

 on most of the British coasts, j^articularly the sandy bays 

 and inlets, buried four or five inches beneath the surface." 

 It is indeed universally distributed, and often occurs in vast 

 abundance in suitable localities. It is distributed through- 

 out the European seas, and ranges as far as the Euxine. 

 It is as common fossil in beds of the pleistocene epoch, 

 wherein it makes its first appearance, as on existing shores, 

 and unerringly marks the shallow waters under which such 

 formations were accumulated.
