The specimens have a length of up to 50 mm. Most of the older 
individuals belong to the typical West Greenland form, with the posterior 
truncata portion of the shell distinctly short (Cf. Jensen: Studier over 
nordiske Mollusker. 1. Mya fig. 86). Only a few shells are similar to 
the variety uddevallensis, Hancock. They have, however, not so thick 
valves as at any rate the fossil shells of this variety, nor is their trun- 
cate end so short. In younger individuals the shell is ovate, and this 
is especially the case when they are quite young.

Common. However the species is not found anywhere in any large 
quantity. The specimens belong partly to the form arctica Linné and 
partly to the more elongated smooth form pholadis LINNE s. rugosa 
Livné. Most of the specimens of both forms arctica and pholadis have 
very thick valves and closely resemble in this respect the valves of this 
species that are found in our late-glacial deposits. In the same locality
