182 CATALOGUE OF THE MOLLUSCA 
water, ten miles from the coast, off Shields. This is a curious 
locality for a species usually found living in the sand close to 
low-water mark. The specimens are more brightly coloured, 
and rather smoother than usual. 
96. TELLINA, Linneus. 
1. T. tenuts, Da Costa. 
Tellina tenuis, Mont. Test. Brit. 59. 
On many of our sandy shores, common. Newbiggin, Holy 
Island, Hartlepool, and Seaton. 
2. T. FABULA, Gmelin. 
Tellina fabula, Mont. Test. Brit. 61. 
Not uncommon on all our sands. 
It is not so local as the last, but less plentiful in particular 
spots. Like most of the other bivalves, it has now become rare 
on Tynemouth and Whitley sands. 
3. T. ponactna, Linn. 
Tellina donacina, Mont. Test. Brit. 58. 
On sandy shores, rare. Warkworth sands (a single specimen). 
—WMr. k. Embleton. Hartlepool— Mr. Septimus Peacock. 
4, T. pvamma, Lovén. 
Shell ovate oblong, very finely striated, much produced an- 
teriorly ; and very short, subtruncated, and obtusely angulated 
posteriorly, without perceptible flexure; colour reddish, yellow, 
or white, with sometimes a few interrupted rose-coloured rays. 
Length rather more than two-tenths of an inch ; breadth, four- 
tenths. 
Tellina pygmeea, Lovén, Ind. Moll. Scand. 42. 
We found a few specimens of this species on the sands at Holy 
Island in 1837, but from its great similarity to 7. donacina, we 
had not ventured to characterise it as distinct from the young of 
that shell, until Dr. Lovén’s description drew our attention to it, 
and a more careful examination of its characters has convinced 
us that it is distinct. The shell is a little more produced in 
front, and shorter and more truncated at the posterior end than 
in 7. donacina; the umbones are consequently more lateral, 
which becomes very obvious when the shell is laid open. The
