Distrihution. — ^Tho most northerly record for this species is in 

 1,750 fathoms (3,200 meters) in Davis Strait. The other Challenger 

 records give it as far south as nearly 40° S. in the South Atlantic and 

 Pearce}'' gives a Scotia record southeast of tlie Falklands. Its extent, 

 then, in the Atlantic is wide. 



Al30ut the British Isles it was found by Chaster at Southport and 

 in the Irish Sea, by Earland at Bognor, and by Heron- AUen and 

 Earland in the Glare Island region on the west coast of Ireland. 



I have had Albatross material from but four stations, all off the 

 northeastern coast of the United States. 



Glohotextnlaria anceps — material examined.
