Distribution. North and South Atlantic, North and South Pacific, and 

 Indian Oceans: 



North Atlantic: Northward to 42 (Hansen); various localities, from 

 off Chesapeake Bay, 2425 fathoms, southward (Bate) ; Sargasso Sea, 500 

 to 700 meters (Ortmann). 



South Atlantic : Off Monte Video, 600 fathoms (Bate) ; South Equa- 

 torial Stream (Ortmann). 



North Pacific: Lat. 27^0 N., long. 138 E. (Stimpson) ; China Sea 

 (Hansen) ; off Japan, 345 fathoms (Bate). Specimens were taken by the 

 Albatross, as follows: 



Off Destruction Island, Washington, 516 fathoms, station 3343. 

 Off Sea Lion Rock, Washington, 477-636 fathoms, stations 3070, 3072, 



373- 



1 The locality " California " attributed to Miers is probably an error, as he appa- 

 rently considered Puget Sound as on the Californian coast, and the specimens in the 

 British Museum which were received from the Smithsonian Institution were undoubt- 

 edly from Puget Sound. (See Proc. ZooL Soc. London, 1879, 52.)
