A few specimens of this species were found at three 
stations, extending in depth from the surface to 630 fathoms. 
Dana’s habitat was Kingsmill Island, Brady obtained it in 
the South Atlantic, and I have found it in the Mediterranean 
and about the Canary Islands.

One of the smallest in size of the genus. Hitherto chiefly 
known from Heligoland and about the western coasts of 
Britain. It occurs at three stations in this collection at 
from 270 to 374 fathoms. I have found it plentiful at times 
about the surface off the south-west of Ireiand.
