DORIDID. 127 
nine, small, simply pinnate, or bearing lateral laminz, and compressed ; 
the margin of the cavity into which they are retractile is fringed with 
small elongated tubercles ; oral tentacles rather flat and linear ; foot 
oblong, rounded at the ends, with a deep transverse groove in front, the 
upper lamina being thin and mesially divided; it does not extend 
behind as far as the mantle-edge ; colour (in spirits) greyish, with a 
yellowish tinge beneath, on the back is a band of faint reddish-brown, 
extending from between the rhinophores nearly as far as the branchie, 
and bordered on each side by an equally broad indistinct blue-band, 
shading into gray on the outer sides ; the two latter bands join together 
between the rhinophores and before the branchiz ; the coloration of 
these bands is produced by a very minute close freckling between the 
small tubercles (Abraham.) 
Length, *52; breadth, -36 inch. 
D. lanuginata, Abraham, P.Z.S., 1877, p. 255, pl. xxix., f 15-17. 
Body ovate, rather convex ; mantle large, expanded all round, with a 
wavy irregular crenate border; it is covered closely with numerous, 
small, soft, linear, tubercles ; rhinophores clavate, short, thick, truncated 
at the apices, and with numerous fine lamellz extending far down ; they 
are retractile within large wide denticulated and tuberculated sheaths ; 
branchiz five, short, broad, tripinnate, set deeply in a pallial cavity with 
raised denticulate margin; the short tubular anus is situated almost 
between the two posterior plumes ; oral tentacles flat, spatulate, and 
longitudinally grooved above ; foot oblong, rounded at both ends, with 
a deep transverse slit in front, the upper lamina divided, and with a 
short process in the middle; flattened, and with crenulate edge at the 
sides and posteriorly ; colour (in spirit) dirty greyish-brown, mottled with 
darker, the dark shade prevailing over the upper surface, except on the 
more central dorsal area; below the tint is uniform and lighter, with 
the exception of a few dark brown spots; the upper surface of the 
border of the foot is freckled and sparsely spotted with dark brown 
(Abraham.)

D. wellingtonensis, 4éraham, P.Z.S., 1877, p. 259, pl. Xxix., 
jf. 27-28; O. tuberculatus, Hutton, C.M.M., p.54., nec. Cuv. Body oval, 
convex, swollen ; mantle thick, fleshy, not extended or flattened at the 
border ; covered with large rounded flat pustules, between which are 
scattered small opaque, whitish, tubercular spots ; rhnophores small, 
clavate, compressed from before backwards, each with more than 
twenty-six small laminee, lying between shallow longitudinal depressions, 
and extending low down ; the apices are styliform, and marked with 
lamin, except at the extreme rounded tip ; they are retractile through 
large, wide, fleshy sheaths ; branchiz seven, ramose, tripinnate, moder- 
ate in size, surrounding the tubular anus, which is placed near, and 
opposite to the interval between the last two plumes ; the whole system 
is retractile within a large deep cavity, the margin of which is crenulate 
and wavy, and can be contracted completely over them ; oral tentacles 
short, thick, tubercular, truncated, and apparently with a central pit on
