DORIS FLAMMEA.
Fam. 1, Plate 4.
DORIS FLAMMEA, Alder and Hancock.
D. coccinea, aliquando pnrpureo-maculata: pallio tubercuhs inequalibus, parviusculis: brancbiis 9,
tripinnatis, coccineis, non effusis, intra foramen retractilibus.
Doris flammed, Aid. and Hanc. in Ann. Nat. Hist. v. 14, p. 330.
Hab. Dredged up on Pecten opercularis in shallow water, Rothesay Bay.
Body about an inch long, and one half as broad, ovate, rounded at both ends, rather
depressed, of a bright orange scarlet, occasionally blotched with purple. Cloak rather ample,
covered with smallish, Unequal, rounded, spiculose tubercles, becoming smaller towards the
margin. Under side of the cloak minutely freckled with opake yellow. Dorsal tentacles
rather large, tapering, orange, with ten or eleven scarlet laminae and intermediate smaller
ones. The Orifices strongly tuberculated at the edges. Branchial not much spreading, but
turned gracefully over, rather paler than the body, composed of nine scarlet plumes imperfectly
three times pinnate, the posterior ones bilobed; retractile within a single cavity.
Head small, with the sides produced into very short, obtuse, angular tentacles. Foot
deep scarlet» rather darker than the body, rounded and slit transversely in front, rarely
extending beyond the body behind; the sides nearly parallel.
This animal lived with us several days. It did not possess much activity. When at
rest the cloak was occasionally much spread, giving it a rounded contour.
Of two specimens obtained, one was of a uniform scarlet; the other had a few blotches
of purple, with an edging of that colour round the branchial plumes.
Doris flammea is very nearly allied to D. tuberculata; but, besides the difference in*
colour, the tubercles and branchiae are smaller, and the dorsal tentacles larger and more
numerously laminated.
