264 MR. P. S. ABRAHAM ON THE [ Mar. 6, 
Rhinophores clavate, short, stout, with about 19 lamine, and retrac- 
tile within unmarginated cavities which are situated close together 
and very far forward. Branchie 8, the last two arising from the 
bases of their neighbours, short, stout, imperfectly tripinnate, retrac- 
tile in a common transversely broad cavity, with the short, broad, 
tubular, triangular anus, which is apparently independently retractile 
within a small cavity, between the two hindermost plumes. Foot 
oblong, rounded in front, acuminate behind ; anteriorily there is a 
shallow transverse groove, between the laminz of which passes cen- 
trally the nodular proboscis : both laminze are notched in the middle ; 
and the anterior one sends a small bilobed expansion round, and in 
front of, the proboscis : the posterior end of the foot extends rather 
beyond the mantle. 
Colour of the spirit specimens dark bluish grey, closely mottled 
with black ; the extreme margin of the mantle and the border of 
the foot are yellowish ; and the tips of the rhinophores pale grey. 
Underneath, the mottling is nearly obsolete. 
Length (in spirit) nearly 30 millims., breadth 16, height 11.

This species is probably closely allied to D. limbata of Cuvier. 

Doripopsis FUMEA, sp. nov. (Plate XXX. figs. 31, 32.) 
Body oblong, rounded at both ends, subdepressed, soft, semi- 
transparent. Mantle semigelatinous, rather puckered above into flat, 
irregular, indistinct pustules; but very little of the rather fleshy 
and wavy border is free. Rhinophores short, stout, clavate, slightly 
kneed in front, the upper portion with diagonal lamine proceeding 
from an anterior small longitudinal ridge; the pedicles are marked 
with annular striz ; they are retractile in cavities with the margins 
produced into very short, nearly smooth sheaths, situated near 
together and very far forward. Branchiz 8, rather slender and short, 
situated around the anus in a transverse ellipse, interrupted behind ; 
the broad, tubular, fimbriate anus is independently retractile ; and the 
whole system is withdrawable into a fleshy-edged common mantle- 
cavity, placed very far back. Foot oblong, broad, rounded in front 
and behind ; the anterior border is thickened ; and through the centre 
passes the lenticular proboscis; in front of the latter lies a small 
bilobed expansion from the foot-border. 
Colour of the spirit specimen clear grey, with here and there 
irreguiar smoky spots cr freckles; a narrow smoky border extends 
all round next to the greyish-yellow extreme mantle-edge. The 
rhinophores are smoky, with the tips light ; the branchize have dark 
pinnulee, and a yellowish tinge near the roots; the anterior part of 
the foot also shows an indistinct yellowish tinge.
