Shell an inch and a half long, and nearly two and a half broad, 

 and an inch and a quarter in height, very convex light and brittle, 

 of a whitish ferruginous color, irregularly striate transversely : the 

 spoon-shaped teeth very narrow in proportion to tho.se of the Ana- 

 tina pubescefls, and without the notch on the broader or hinder part : 

 the beaks meet close together at their points. 



Full grown shells are of rare occurrence : the finest which we 

 have seen, exceeding the ^proportions above described, was found by 

 our young and ardent friend Miss Hill, of Down-house, near Bristol. 



We believe that the large very convex and light shell described by 

 Montagu, in his Suppl. p. 166, under the name of Ligula distorta, 

 as a remarkable specimen of his Mya distorta, was this species. 

 He does not notice the teeth, which in every form and variety in the 

 Anatina distorta are projecting horizontally inwards ; and placed 

 laterally oblique in all the sizes of growth of the Anatina convexa. 



Anatina testa depressd ohlongd, latere antico anyulato truncato, den- ruiescens. 

 tibus postici emarginatis.
