Many specimens have been found in the material examined which 

 may, in a general way, be referred to this species, but well defined 

 material is not abundant. Specimens referred to this species have 

 occurred in comparatively shallow water in various parts of the 

 region from 24 to 510 fathoms (44 to 933 meters), with bottom tem- 

 peratures, where recorded, 41.2° F. (5.1° C), 44.3° F. (6.8° C), 

 52.3° F. (10.1° C), and 75.7° F. (24.2° C). As a rule it seems to 

 occur in warm and shallow water.
