Supplementary Report on the Blake Cephalopods. By A. E. VERRILL. 
Tue following paper includes the results of an examination of a small 
collection of Cephalopods received after my former report had been 
printed. The specimens are not numerous, but among them there are 
two very remarkable new genera, of unusual interest. 
All the specimens in this lot were taken in the West Indian region, 
and mostly in rather deep water. 
Abralia megalops VERRILL.

Plate ITI. Fig. 4. 
A small immature specimen occurred at Station 294, in 137 fathoms, off 
Barbados, 1878-79. 
The body is moderately long, pointed posteriorly, with the anterior mantle- 
edge prolonged into a broad, blané median angle. Caudal fins large, the base 
rather large, occupying nearly one third the length of the mantle. Taken 
together the outline is broad-rhomboidal, and dlighity sagittate; the outer angle 
_ of the fin is obtusely pointed ; the anterior margin is broadly ee curved, 
projecting forward somewhat beyond the base. Head rather large. Eyes very 
large. Arms slender, the dorsal ones shorter than the others, which are sub- 
equal, Tentacular arms long, very slender, more than twice as long as the 
sessile ones. The connective cartilage at the base of the siphon is large, broad- 
est posteriorly, tapering to a blunt point anteriorly, with a central longitudinal 
furrow, having thickened margins.
