Distribution. — The type station for this species is Albatross D2384, 

 in 940 fathoms, in the northern part of the Gulf of Mexico. Flint

 Block Island (D2584, 2586, 2221, 2234), with a range of depth from 

 328 to 1,525 fathoms. In the Albatross material I have examined it 

 has occurred sparingh^ from Georges Bank southward to Cape
