Dr. E. F. Kelaart on new species of Ceylonese Mollusca, 803 



Doris corrugata, Kel. 



Body nearly 1 inch long, oval, whitish. Mantle coriaceous, cor- 

 rugated, and studded with small tubercles ; those on the sides 

 larger, and each with a spine j of a pale watery-green colour, 

 black-spotted under surface, also greenish, and spotted with 

 small dots. Dorsal tentacles short, open, greenish, lamellated. 

 Branchial plumes grey, seven or eight, short, pinnated. Foot 

 pale green, narrow, shorter than mantle. Oral tentacles short, 

 triangular, pointed. 



I have seen only one live specimen of this curious Doris. 



Doris picta, Kel. 



Coriaceous. Body 2^ inches long. Mantle large, oval, entirely 

 covering the foot; upper surface granular, of a yellowish- 



. brown colour, splashed with large and small irregular brick- 

 red spots ; under surface white, and near the body painted with 

 small and large bright-red spots. Dorsal tentacles clavate, 

 laminated, slightly truncated ; sheaths large, granular. Oral 

 tentacles long, pointed, white, spotted with red. Foot broad> 

 shorter than mantle, white. 



This remarkably painted Doris is found in deep water. Occa- 

 sionally it burrows in the sand, where it lies for hours, its plumes 

 and dorsal tentacles alone being uncovered. 



Doris bellicosa, Kel. 



Coriaceous. Body 2 J inches long. Mantle large, oval; upper 

 surface granular and covered with small spines; of a dull 

 brick-red or chocolate colour, and irregularly streaked with 

 pale yellow ; under surface of mantle white, splashed and 

 spotted with chocolate. Branchial plumes six, large, bipin- 

 nated, of a dull rose-colour, and speckled with yellow in small 

 specimens. Dorsal tentacles with small, clavate, pointed apex. 

 Oral tentacles white, short, pointed. Foot broad, oval, of a 

 dark red colour, with a pale whitish edge. 



Found in deep water in the Inner Harbour of Trincomalee. 

 The mantle of this species much resembles that of D. picta; but 

 its spines and chocolate-coloured foot sufficiently distinguish it 

 from that species, which has a white foot and beautifully 

 painted under-side of mantle. They live for many months in a 

 vivarium. 



Doris castanea, Kel. 



Carneous. Body IJ inch long. Mantle thick, granular and 

 tubercular, of a reddish chestnut colour. Dorsal tentacles 

 red, short, laminated ; tip produced, whitish. Oral tentacles
