122 MESSRS. ALDER AND HANCOCK ON 
Tongue as in D. tuberculata; no collar. The cloak appears to be well supplied with 
spicula. 
Not common. Only one specimen is in the collection. 
This curious Doris, from its sheathed tentacles and dorsal protuberances, shows some 
affinity with D. spongiosa ; but it differs from that species in the peculiar arrangement 
of the dorsal area, as well as in its very sombre and unattractive appearance. 
Doris carinata, n. sp. (PI. XXIX. figs. 5, 6.) 
Body oval, rather raised at the sides, and flattish on the back. Cloak greenish olive- 
coloured, darker towards the back, regularly covered with small fulvous tubercular 
spots: an area on the centre of the back, extending from the tentacles to the branchiz, 
is pale, and covered with whitish tubercles ; this area is broad between the tentacles, 
linear down the back, and expands into a circle in front of the branchiz. Dorsal ten- 
tacles clavate, brownish, without sheaths, the cavities with pale margins. Branchial 
plumes numerous, stout, greenish olive, forming a complete circle. Length 3 inch. 
There is no specimen in the collection. 
Doris APICULATA, n. sp. (Pl. XXX. fig. 8.) 
Body broadly oval, rather convex. Cloak firm, raised into reticulated ridges fre- 
quently radiating from elevated conical centres, each of which bears a delicate style or 
filament ; the ridges and centres are crowded with minute, pale, spiculose tubercles, 
the interspaces being comparatively smooth and of a dark brown colour approaching 
to black ; the colour of the elevated ridges and apices of the cones (which do not extend 
to the margin of the cloak) is yellowish, as are also the sides of the cloak, the latter 
being rather paler and obscurely blotched with brown ; a row of minute dark spots runs 
along the extreme pallial margin. Under side minutely reticulated with pale lines, 
giving it a sponge-like appearance ; there are also a few scattered pale brown spots. 
Dorsal tentacles clavate, rather slender, pale, with the laminated portion dark ; retrac- 
tile within short sheaths, the margins of which are beset with numerous minute points. 
Head small, with short lateral linear processes or oral tentacles. Branchial plumes five, 
tripinnate, freckled with blackish brown ; the margin of the cavity minutely and irre- 
gularly denticulated. Foot narrow, plain below, spotted with brown above; the anterior 
lamina rather ample and notched. Length about an inch. 
Tongue as in D. tuberculata ; no collar. 
This curious species comes very near to the Doris inci, figured in Mrs. Gray’s 
‘Figures of Molluscous Animals.’ It is not uncommon ; only a single individual was 
preserved. 
Doris FruNngEBRIS, Kelaart. (Pl. XXX. figs. 9, 10.) 
Body oblong, white, with black spots. Cloak covered with minute, pointed, spiculose
