OF NORTHUMBERLAND AND DURHAM. 89 



anterior lateral tooth is also more remote, and the sinus of the 

 pallial impression proportionately smaller than in T. donacina, 

 as pointed out by Dr. Loven. A specimen sent us by that dis- 

 tinguished naturalist enables us to speak with confidence as to 

 the identity of the species. 



5. T. SOLIDULA, Putt. 



Tellina solidula, Mont. Test. Brit. 63. 

 Not uncommon on many of our sandy shores. 



6. T. CRASSA, Penn. 



Tellina crassa, Mont. Test. Brit. 65. 



At Holy Island and some other parts of the north of North- 

 umberland, not uncommon. Embleton Bay, plentiful. — Mr. 

 Emhleton. Cullercoats, rare. We take the Arcopagia ovata of 

 Brown (found at Newbiggin) to be a variety of the young of this 

 species, which is much more ovate in its early stages. 



Tellina punicea. " We met with dead shells with the valves 

 united, by dredging off Holy Island." — Capt. Brown, III. Pec. 

 Conch. 100. 



Tellina pellucida, Brown Illust. Bee. Conch. 101, t. 40, f. 22, 

 " found at Seaton, county of Durham," by Sir W. C. Trevelyan, 

 we are unacquainted with, but, judging from the description 

 and figure, it does not appear to belong to this genus. 



Tellina squalida of Sir C. Sharp's list we have reason to be- 

 lieve is only a large variety of T. tenuis. 



Tellina carnaria has probably been introduced into Mr. 

 Winch's list by some mistake. It is not a British species. 



97. PSAMMOBIA, Lamarck. 



1. P. Feroensis, Gmel. 



Tellina Feroensis, Mont. Test. Brit. 55. 

 From deep water, frequent. 



2. P. vespertina, Gmel. 



Solen vesperti7ius, Mont. Test. Brit. 54. 

 From the fishing boats, Cullercoats, rare. — J. II. F., and Mr. 

 Chas. M. Adamson. Whitburn. — Rev. G. C. Abbes. 



3. P. TELLINELLA, Lam. 



Psammobia Jiorida, Turt. Brit. Biv. %(i, t. 6, f. 9.
