88 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, Linnceus. 



1. T. TENUIS, Ba 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 fahula, 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. DONACiNA, Linn. 



Tellina donacina, Mont. Test. Brit. 58. 

 On sandy shores, rare. Warkworth sands (a single specimen). 

 — Mr. R. Emhleton. Hartlepool. — Mr. Septimus PeacocTc. 



4. T. PYGM^A, Loven. 



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 pygmcea, Loven, Ind. Moll. Scand. 42. 



We found a few specimens of this ppecies on the sands at Holy 

 Island in 1837, but from its great similarity to T. donacina, we 

 had not ventured to characterise it as distinct from the young of 

 that shell, until Dr. Lov^n'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 T. donacina ; the umbones are consequently more lateral, 

 which becomes very obvious when the shell is laid open. The
