ATRYPA fimbriata. 
TAB. DCXVII.— /g. 4. 
Spec. Char. Orbicular, becoming transversely oval 
by age, depressed ; the middle of each valve a 
little flattened longitudinally; surface uneven, 
imbricated and striated. 
Syn. Spirifera fimbriata. Phillips, loc. cit. 220. 
From the mountain limestone of Kendal in Westmore- 
land. The specimens do not well agree with the descrip- 
tion given by Prof. Phillips of Sp. fimbriata \ but they are 
considered to belong to that species by Mr. Gilbertson, in 
whose cabinet they are.
