The general shape of the sucker, too, agrees fairly with 

 that figured by Lesueur. 



Verrill's account of the pen of his D. hyperhorea describes 

 that of Loligo pavo, Lesueur, very well, for the latter, like 

 the former, terminates posteriorly in a hollow cone. This 

 is not shown in Lesueur's drawing, though it is quite evident 

 in the specimen; the drawing indeed is merely a sketch 

 giving a general idea of the form of the pen, which has never 

 been removed from the specimen. 



The passages in quotation marks above are taken from 

 Verrill's description, and when compared with d'Orbigny's 

 figures, they leave, I think, little room for doubt that the 

 two species in question are the same. Of course at present 

 the identification lacks the crucial test of comparison of the 

 actual specimens, and therefore I append a query to Desino.- 

 teuthis hyperhorea in the synonymy.

The Body. — The body is elongated, tapering posteriorly; 

 the mantle is thin, enclosing an enormous branchial cavity, 

 only a small portion of which is occupied by the viscera ; its 

 anterior border projects slightly forwards in the middle line 

 dorsally and at each lateral attachment; in the former of 

 these positions the surface of the body is almost continuous 

 with that of the head, only the very slightest fold of the 

 mantle marking them off. A number of purplish chromato- 

 phores cover the mantle, and there are also a number of 

 larger spots disposed in irregular rows, of w^hich there are 

 about ten down the mantle. The caudal fin is fully half the 

 length of the body and of an elongated cordate form. The 

 siphon is triangular, and reaches to about the centre of the 



^ This species will be figured in the forthcoming Report on the "Challenger " 

 Cephalopoda.
