254 MR. P. S. ABRAHAM ON THE [ Mar. 6, 
deep cavities having the margin produced into short, wide, tubercu- 
lated sheaths. Branchize plumose, situated in a cavity very far back, 
their number not determinable in the specimen; but apparently 
they are not very numerous. Oral tentacles linear, pointed. Foot 
elongate, nearly as broad as the body, rounded and _ transversely 
grooved in front, with the upper lamina raised and notched ; acumi- 
nated and produced beyond the mantle at the back. 
Colour of the spirit specimen light greyish brown, blotched with 
reddish in front of the rhinophores and near the branchie. 
Length (in spirit) 21 millims., breadth 8, height 7.

Doris ANALAMPULLA, sp. nov. (Plate XXIX. figs. 8-10.) 
Body oval, convex. Mantle large, with a thin wavy border ex- 
tending all round, closely covered with minute, subequal, rounded, 
granular tubercles. Rhinophores clavate, with rounded apices and 
minute diagonal lamine extending far down; their cavities with the 
margin raised and tuberculated. Branchize 7, small, indistinctly bipin- 
nate, set, at a little distance, around a long, tubular, bottle-shaped 
anus, which is situated almost in the interval between the two hinder- 
most plumes; the whole retractile in a cavity with slightly raised 
border. Oral tentacles small, linear, and pointed. Foot elliptic- 
oblong, rounded before and behind, indistinctly grooved in front, 
flattened at the border, especially posteriorly, where it is nearly co- 
extensive with the end of the mantle. 
Colour (in spirit) semitransparent white, with a yellowish tinge on 
the back. 
Length (in spirit) 15 millims., breadth 10.

Doris LABIFERA, sp. nov. (Plate XXIX. figs. 13, 14.) 
Body oblong. Mantle not much extended beyond the foot, but 
ample in front of the head, covered with close, small, unequal, rounded 
tubercles, which become smaller upon the border. Rhinophores 
short, clavate, with a slight longitudinal depression in front, from 
which the lamine arise ; their cavities with slightly raised tubercu- 
lated margins. Branchie 6, short, tripinnate, embracing in a com- 
plete circle the central short tubular anus; the divisions between 
the plumes do not extend far down, except in the case of the two 
hindermost ; the cavity into which they are retractile has the mar- 
gin raised into a short, tuberculated, denticulated sheath. Oral 
tentacles small, elongate, conical, and pointed. Foot oblong, trun- 
cated and transversely grooved in front, with the upper lamina 
notched ; behind, it is narrrower and rounded, and reaches as far as 
the posterior edge of the mantle; the border is flattened and 
minutely tuberculated above. 
Colour (in spirit) purplish grey, with dark blotches and mottling, 
produced by a minute purple dotting between the tubercles; the 
midribs of the branchie are violet-grey, from a similar minute freck- 
ling; the other parts of the branchize and the rhinophores are
