There can be little doubt that this is the D. tuberculosa of Quoy & Gaimard, and 
perhaps it may also be the D. carbunculosa of Kelaart, though, as the conspicuous white 
spots on the under side of the cloak are not described by the latter naturalist, nor 
represented in his drawing, some doubt may remain respecting it. The large cones 
that stud the upper surface of the cloak give this species a very peculiar appearance. 
It is not unfrequent on the Coromandel coast ; two specimens were brought home. 
Doripopsis pustuLosa, n. sp. (Pl. XXXI. figs. 8, 9.) 
Body oval, rather depressed. Cloak with large conical pustules irregularly disposed 
over the back, of a dull ochreous-yellow colour, concentrically ridged or lineated, with a 
largish tubercle on the apex of each, and occasionally a few smaller ones at the sides ; 
the pustules nearly touch each other at the base, the interspaces being narrow and of a 
dark brown colour; margin of the cloak pale yellowish white, with ochreous-yellow 
stripes running in pairs towards the edge. Dorsal tentacles rather small, bent a little 
backwards, brown, with a white ring below the laminz, a spot of the same in front, and 
a white apex. Branchial plumes five, moderate-sized, yellowish, with brown lines 
along the ramifications. Length 1? inch. 
As the specimen of this species was lost, the character of the under side cannot be 
given. It has some resemblance to the last, of which it may possibly be the young. 
Dorivopsis niGRA, Stimpson, sp. (Pl. XXXI. figs. 13, 14, 15, 16.) © 
Body elliptical, rather convex. Cloak smooth and soft, black with a bluish tinge, 
rather paler towards the margin, freckled with minute, well-defined, white spots, larger 
and more numerous towards the margin; on the back they become clustered, generally 
round a larger spot ; under side black, without markings. Dorsal tentacles clavate, 
black, with pure-white tips ; the upper portion bent backwards ; lamine eighteen or 
nineteen, well developed, and divided in front by a narrow ridge; retractile within 
simple cavities. Branchial plumes eight, forming a circle incomplete behind, tripin- 
nate, uniformly black, soft, and plumose. Head indistinct, indicated by a slightly 
arched elevation in front of the foot, produced into points at the sides: mouth situated 
in a depression dividing the anterior edge of the foot, behind which is a small area. 
Foot of a smoky colour. Length from 13 to 3 inches. 
Var. a. Cloak with larger white spots on the sides, and compound ones on the back ; 
an obscure red line surrounding the cloak at a little distance from the margin, best
