 at least, one turgid and short in front, the other flatter and longer." "They 

 are very close to each other at best, and all found in the Gulf" of St. 

 Lawrence.

Common throughout the entire region, usually at or a little below low- 

 water mark. It is abundant on the shores of the Maritime Provinces, and 

 Dall says that it ranges "in cool water south to (xeorgia." In the Gulf of 

 St. Lawrence it is widely distributed, and it has been found as far up the 

 river as Kamouraska by Sir J. W. Dawson. Packard records it as abundant 

 on the Labrador coast, and Fabricius and Moller found it at Greenland. It 

 is a circumpolar species, and specimens from British Columbia have usually 

 been catalogued as Macoma inconspicua (Broderip and Sowerby). On the 

 Pacific it has been collected in northern Japan, and as far south on the
