Fam. 1, Plate 4. 



DORIS FLAMMEA, Alder and Hancock. 



D. coccinea, aliquando purpureo-maculata : pallio tuberculis inequalibus, parviusculis : brancliiis 9, 

 tripinnatis, coccineis, non effusis, intra foramen retractilibus. 



Doris flammea, Aid.' and Hanc. in Ann. Nat. Hist. v. 14, p. 330. 



Hub. 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. Branchiae 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. 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. tubercidata; but, besides the difference in 

 colour, the tubercles and branchiae are smaller, and the dorsal tentacles larger and more 

 numerously laminated.
