Variety differing from the typical in the fewer chambers, smaller 

 size, more compact test, and broadly rounded periphery. 



In Buzzards Bay this variety is a very common form occurring 

 LQ several dredge hauls in shallow water. It seems to be very different 

 from the larger form in more northern, colder waters,

The generic position of this species is somewhat in doubt. It has 

 some of the characters of Cancris in some specimens which have a 

 thin plate over the ventral side of the last chamber, and the dorsal 

 side of many specimens resembles Cancris. It is however subject to 

 much change in the last few chambers in adults probably due to 

 attachment. The peculiar coarsely perforated last chamber is dis- 

 tinctive.
