Dr. E. F. Kelaart on new species of Ceylonese Mollusca, 297 



Doris rufopunctata, Kel. 



Body I" inch long, oval_, compressed, of a white colour. Mantle 

 coriaceous, of a light brick-red colour, and speckled with 

 circular spots of a darker reddish-brown colour. Branchial 

 plumes five, small, bipinnate, greyish-rufous, speckled. Dor- 

 sal tentacles short, clavate, pointed, laminated, without sheaths, 

 of a rufous-brown colour. Oral tentacles white, linear. Foot 

 whitish, short, grooved and notched in front, speckled with 

 rusty. Under part of cloak whitish, and also speckled rusty. 



This stiff-looking Doris is occasionally seen in a circular form. 

 Rarely found, among pearl oysters. Very tenacious of life. 



Doris griseaj Kel. 



Body li inch long, gelatinous. Mantle of a dark ashy-brown 

 colour, closely speckled with reddish-brown and white spots, 

 and two or four longitudinal rows of larger blackish irregular 

 spots. Tentacles clavate, laminated, ashy brown, speckled with 

 white. Branchial plumes five, whitish, speckled with grey, 

 tripinnate. Mouth surrounded with a white veil (?). Foot 

 whitish, spotted with reddish brown, notched in the fore part, 

 covered entirely by the mantle. Some specimens are more 

 reddish-coloured than others. The young are nearly always 

 more ashy-coloured. 



A very common species, found from March to September at 

 low-water, on rocks surrounding Fort Frederick, and also in 

 the Inner Harbour. Lives a long time in the aquarium. Ova 

 white, in three or four white coils. This Doris can elongate 

 itself into the shape of a leech. 



Doris papulosa J Kel. 



Body I inch long, white, brown-spotted. Mantle coriaceous, 

 covered with large papillse, each rising from a circular tuber- 

 cular base or ring ; bufi", and spotted with dark reddish brown ; 

 a row of larger spots round the margin ; a dark brown line 

 runs from base of tentacles to branchiae. Dorsal tentacles 

 large; apex clavate, laminated, of a light green colour, speckled 

 white. Oral tentacles short, linear. Foot whitish, and spotted 

 with rusty brown, shorter than mantle. Branchial plumes 

 six, short, tripinnated. Three posterior plumes rusty- coloured, 

 anterior ones whitish. 



This species resembles Doris rufopunctata ; but its green dorsal 

 tentacles and papillose tubercles on mantle sufficiently distin- 

 guish it from other species. Ova white, laid in four narrow 

 waved coils.
