Sarsii goes deeper down and has not been taken in less than 40 fathoms, while on the contrary 

 il has been captured near the Fseroes at a depth of 388. Sabinea hystrix was obtained off 

 Guadeloupe at a depth of 734, off the east coast of the United States in water of 353 — 888, 

 and south-west of Iceland even at 191 2 fathoms ; this species occurs thus at the greatest depth. 

 Sabinea indica, finally, was taken from 218 fathoms upward.
