Shell oblique, somewhat ovated, furrowed transversely, and of an 

 norn colour. 



Tellina Riv alis : testa oblique subovata transversim sulcata cornel 

 colon*. Maton. Linn. Trails, vol. 3. 



The English naturalist is indebted to Dr. William Maton, author of 

 the Tour of the Western Counties, for the discovery of this new and 

 interesting British species. The first account of it appeared in a paper 

 presented by him to the Linnaean Society, and afterwards inserted in 

 their Transactions ; and it is to this gentleman also our thanks are 

 due for the specimens figured in the annexed plate. We have seen it 

 since in the Collection of William Pilkington, Esq. Whitehall; who 

 recently found it in the river near Hungerford in Berkshire. 



Dr. Maton, in his remarks on this species, says, " It does not appear 

 to have been described, and probably was never seen by Linnaeus, nor 

 has it been noticed by any English writer on Conchology ; a figure, 

 however, o£ it occurs in GualterVs Index, Testacrum. Conchy- 

 liorum {Tab. l.fg. C. C.) but has been referred to by Professor
