Excellent specimens of this species were obtained at numerous 

 stations well scattered tliroughout the region, but mostly in medium 

 depths. The range of depths is from 80 to 554 fathoms (146 to 1,012 

 meters), with an average of 229 fathoms (419 meters), and the bottom 

 temperatures from 53° F. to 58.6° F (11.7° C. to 14.7° C), with 

 an average of 55.6° F. (13.1° C). 



Some of the largest specimens measure as much as 25 mm., and 

 often specimens show considerable constriction, usually toward the 

 apertural end, but also occasionally in the middle of the test. This 

 is one of the finest species in the region.
