TELLINA. TELLEN. IJ3 



15. Tellina Laskeyi. Laskeys Tellen. 

 Montagu, pi. 28. f. 3. 



Shell oval-oblong, smooth, rounded at one end and ob- 

 tusely pointed at the other : color purplish-white, darker 

 towards the hinge, more or less clouded with purple in the 

 middle, covered when fresh with an olive yellow skin; in- 

 side white round the margin, and channelled from the teeth 

 almost to the end of the longer side : hinge with a single 

 primary tooth in one valve, and two approximate slightly 

 cloven ones in the other : length half an inch ; breadth 

 three-quarters. 



In the Firth of Forth, discovered by Captain Laskey $ 

 and is exceedingly rare. 



C. More or less orbicular, 16 to 32. 



16. Tellina maculata. Spotted Tellen. Fig. 13, 

 Shell oblong inclining to orbicular, thin, brittle, whitish 



covered with numerous irregular dull brown spots and 

 blotches, strongly and regularly striate transversely, and 

 crossed by extremely fine longitudinal lines in the inter- 

 stices, which however do not cut the concentric rounded 

 striae, well rounded at both the sides, the anterior end a 

 very little produced and narrower ; both valves equal : 

 beaks a little prominent, not quite central; inside yellowish- 

 white, polished, with a plain margin : hinge with two teeth 

 in each valve and a remote lateral one, the middle tooth 

 cloven : length about an inch ; breadth an inch and a quarter. 

 This is most probably the T. maculata, so imperfectly de- 

 scribed by Mr. Adams, in the third volume of the Linnean 

 Transactions. We found it, in a perfect state, at Bantry bay: 

 rare. v. m.
