specimens at station 246 in 2,050 fathoms in the middle of the North 

 Pacific. Goes records it from three Albatross stations off the coast 

 of Mexico in 660-995 fathoms. His selected material which I have 

 seen, from the entrance to the Gulf of California, is very large and 

 more like the typical Arctic material. I have found the species in 

 material in 2,085 fathoms, Albatross station H2833, midway between 

 San Francisco and the Hawaiian Islands; also from several stations 

 south of Japan in the colder water, in 139-1,551 fathoms.

Distribution. — Brady described this species from Challenger station
