 Inhabits the coasts of Norway. Linnaus. 

 Shell about an inch long, thin, brittle, marked with longitudinal 

 ribs, and obsolete transverse striae ; the colour is dirty white, 

 and Linnaeus says, the upper valve so much resembles Pa- 

 tella lutea, that when separated, it might be readily mis- 

 taken for it ; the umbones are smooth, and the summits in- 

 distinctly recurved. 



squama. 11. Shell oval-oblong, with the convex 

 valve minutely striated longitudinally, and the 

 other perforated near its middle.

Inhabits the coasts of Norway. Chemnitz. 



Shell about an inch and a quarter long, and near an inch broad, 

 with the upper valve only slightly convex, and marked with 

 delicate longitudinal striae, radiating from the summit ; the 

 lower valve is thin and flat, and thickened at the margin, and 

 has a large oval perforation, which Bruguiere says, is more 

 nearly central than in any of the neighbouring species. 



bifida. 12. Shell oblong ; with longitudinal, some- 

 what imbricated, bifid striae on the convex 

 valve.
