84 CATALOGUE OF THE MOLLUSCA 



Donovan, wlio figures it from a specimen " found near Hartlepool, 

 on the coast of Durham." The shell had most likely got there 

 by some accident, as the species is not known to inhabit our 

 coast, and is scarcely British. 



Family. V'enerid^, Fleming. 

 90. ARTEMIS, Poli. 



1. A. EXOLETA, Linn. 



Venus exoleta, Mont. Test, Brit. 116. 

 From deep water, frequent ; more especially towards the north 

 of Northumberland. 



2. A. LINCTA, Pult. 



Cytherea lincta, Flem. Brit. Anim. 445. 

 Var. Artemis comta, Lov^n Index Moll. Scand. 39. 

 At different depths, on most parts of the coast, not uncommon. 

 A specimen of his Artemis comta, sent to us by Professor 

 Loven, enables us to state that it is similar to what we consider 

 a variety of Artemis lincta, found on our coast. 



3. A. UNDATA. 



Venus undata, Mont. Test. Brit. 117. 



From deepish water, not common. 



We place this species provisionally here, though scarcely a true 

 Artemis, as there is some difficulty in assigning it a generic appel- 

 lation. The name of Mysia, given to it by Dr. Leach, has been 

 appropriated by Capt. Brown to a different shell, Tellina rotun- 

 data, Mont, (Conchologists' Text Book, 150), and is consequently 

 synonymous with Diplodonta, Bronn. 



91. VENUS, Linnceus. 



I. V. VERRUCOSA, Linn. 



Venus verrucosa, Mont. Test, Brit. 112. 

 Seaton Carew, single valves. — Hiss Elizabeth Backhouse. It 

 is also in Sir C. Sharp's Hartlepool list, and Capt. Brown says 

 that it is found on the Northumberland coast. We have never 

 been so fortunate as to meet with it, and suspect it may have 

 been derived from ballast.
