112 Description of New and Little knoivn Species of 



orifice in a nipple-like process, situated between the anterior 

 and middle third of body. Foot long, and broad; terminating 

 posteriorly in a lancet shaped point, about \ inch from body ; 

 white, with a delicate light orange red line on the edge of 

 the foot ; this line is carried partially on each side of head. 

 Tentacles 2, dorsal ; short, conical, pointed ; upper half in- 

 distinctly laminated ; of a light orange red colour at tip ; base 

 colourless, transparent. Ova yellow, deposited in bead-like 

 coils. They generally deposit the coils on branches of sea 

 weed. Sometimes, this Doris resembles a miniature fantail 

 pigeon ; particularly when perched on sea weed, and the 

 small marabout plumes are elongated. 



Found on rocks and sea weed near Sober Island, 

 This elegant creature does not resemble any of the de- 

 scribed species. The form of the body is not unlike that 

 of the genus Ancula. Its nearest approach, in other par- 

 ticulars, is to Polycera. 



I venture to make a distinct genus of this Boris, and 

 dedicate it to Sir Walter Trevelyan, to whom I am in- 

 debted so much for the liberal aid he has afforded me in my 

 researches into the Natural History of Ceylon. 



Fam. Tritoniam. 



Meliboea. Bang. 



Animal elongated, with a narrow, channelled foot and long 

 slender tail ; sides of the back with pairs of tuberculated 

 lobes, easily deciduous ; tentacles cylindrical, retractile into 

 long trumpet shaped sheaths : head covered by a lobe-like 

 veil ; sexual orifices behind right tentacle ; excretory behind 

 first gill on the right side. — (Woodward)
