Station 1124, in 640 fathoms, off Martha’s Vineyard, 1882. 
The only specimen previously known was from off Newfoundland, 
in about 150 fathoms, probably from a fish stomach,

This species was taken by the Albatross, in 1883, at station 2034, 
in 1346 fathoms, one young; station 2036, in 1735 fathoms, frag- 
ments; station 2037, in 1731 fathoms (one arm). 
At station 2034, in 1346 fathoms, a very young female specimen 
of this species was taken by the Albatross in 1883. 
In form and 
general appearance it differs but little from the large specimens 
described and figured by me. 
But the body is relatively shorter and 
broader, and the chromatophores are larger, more regularly scattered 
and more distinct.

PLATE XXVIII, FiguREs 1, la, 10. 
A young living specimen of this species was captured while swim- 
ming at the surface, about 100 miles south of the eastern end of Long 
Island, by Dr. Kite, surgeon of the Fish Hawk. From this specimen, 
after it had been in too strong alcohol for two or three days, the fig- 
ures on Plate xxvilI were made. 
Owing to the strength of the
