XXXII. — Descriptions of new and little-known species of Ceylonese 

 Nudibranchiate Mollusks. By Dr. E. F. Kelaart. 



Doris gloriosa, Kel. 



Syn. Doris marginata (?), Leuckart. 



Body nearly 3 inches long, oblong, of a pinkish colour, mi- 

 nutely dotted with red and white. Mantle large, oval, broad, 

 when expanded entirely covering the foot. Back mottled 

 with pink, red, and yellow, and] minutely punctulated with 

 red and yellow ; edged broadly with white, then with a broad 

 rich-red line; adjoining this is a whitish space; and car- 

 ried round the mantle, near the body, is a still more brilliant 

 blood-red line, with internal club-shaped prolongations of the 

 same beautiful purple-red colour. Interspace and for about 

 \ inch of breadth of the back, the mantle is again whitish, 

 with shades of purple and yellow nearer the beautifully mot- 

 tled back. The under side of the mantle has also a broad 

 white edge, the rest brilliantly variegated with dotted purple, 

 yellow, and red splashes. Branchiae seven or eight, large, 

 branched, each rising from a separate cavity in a circle about 

 half an inch from a protruding yellow-coloured anal orifice. 

 Plumes roseous, with red midribs. Dorsal tentacles large, 

 clavate ; apex pointed, slightly truncated, on inner edge lami- 

 nated ; colour pinkish and spotted with yellow ; ridge of cavity 

 spotted with yellow and red. Head large, protruding nearly 

 J inch from mantle. Mouth near the foot, situated in the centre 

 of an oval projection ; and on each side a long, broad, toothed 

 leaflet or oral appendage, red and dotted like the head. Foot 

 long, broad, with parallel sides, rounded and transversely 

 split in front. It has a broad lemon-coloured edge, with 

 transverse striae ; the rest pinkish red, not spotted ; a dark- 

 purple spot in centre, produced by the internal viscera. 



This is by far the most beautiful species of Doris or Sea- 

 nymph I have ever seen ; and none but a good artist could do 

 justice to its resplendent beauties. The large, ample surface of
