Excerpt:... coccinea, aliquando purpureo-maculata: pallio tuberculis inequalibus, parviusculis: branchiis 9, tripinnatis, coccineis, non effnsis, intra foramen retractilibus. Doris flammea, Ald. 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 frecked with opaque yellow..Dorsal tentacles rather large, tapering, orange, with ten or eleven scarlet laminae and intermediate smaller ' ones. Theorifices strongly tuberculated at the edges. Branchize not much spreading, but turned gracefully over, rather paler than the body, composed of nine scarlet plumes imper. fectly 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.
