OF NORTHUMBERLAND AND DURHAM. 183 
anterior lateral tooth is also more remote, and the sinus of the 
pallial impression proportionately smaller than in 7”. donacina, 
as pointed out by Dr. Lovén. A specimen sent us by that dis- 
tinguished naturalist enables us to speak with confidence as to 
the identity of the species. 
5. T. sonmpuna, Put. 
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. 
E'mbleton. 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, Ill. Ree. 
Conch. 100. 
Tellina pellucida, Brown Ilust. Rec. 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 7’. 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. Feroensts, Gimel. 
Tellina Feroensis, Mont. Test. Brit. 55. 
From deep water, frequent. 
2. P. vEsPERTINA, Gmel. 
Solen vespertinus, Mont. Test. Brit. 54. 
From the fishing boats, Cullercoats, rare.—J. H. F., and Mr. 
Chas. M. Adamson. Whitburn.—ev. Gt. C. Abbes.

Psammobia florida, Turt. Brit. Biv. 86, t. 6, f 9.
