Dr. E. F. Kelaart on new species of Ceylonese Mollusca. 301 



mantle pinkish ; and near the body there is a broad, undu- 

 lating reddish band, terminating abruptly on each side below 

 the foot, not unlike in appearance to some cutaneous disease. 

 Dorsal tentacles long, pinkish and smooth for two-thirds of 

 their length ; apex clavate, laminated, truncated, of a pale brown 

 colour. Oral tentacles long, conical, pinkish. Branchial 

 plumes six, large, pendent, tripinnated; plumes pinkish red 

 and speckled with white ; midribs greenish. Foot much shorter 

 than mantle, deeply grooved and notched in front, obtusely 

 pointed posteriorly ; of a light pink colour, except the edge, 

 which is of a lemon-colour, with transverse strioe. 



The whole animal gives one more the idea of a horrid disease 

 than the charms of a Sea-nymph. This species is semigelati- 

 nous, and very glutinous on the surface, particularly the mantle. 

 When dead, it rapidly dissolves, and cannot be preserved in 

 spirits. The largest specimen I have seen measured 8 inches 

 long and 5 inches broad. It will not live more than a few days 

 in the aquarium. Ova of a beautiful red colour; coil | inch 

 broad and 18 inches in length. This species resembles Doris 

 carbunculosa ; but the smooth nodules and the red ova of the 

 former will always be sufficient marks of distinction. 



Doris carbunculosa, Kel. 



Body nearly 4i inches long, oblong-oval, of a pinkish-purple 

 colour. Mantle semigelatinous, broad and long, of an oval 

 form, and purplish-brown colour, studded with numerous 

 large warty nodules, and with larger ones rising from a raised 

 tubercular ringed base : nodules of a deeper brown colour ; 

 some have also a greenish tinge, and others are variegated 

 with white. Dorsal tentacles long, produced, clavate, trun- 

 cated superiorly, laminated, of a pale purplish colour. ]\Iouth 

 with a small triangular-shaped veil. Branchial plumes five, 

 large, broad and long, closely tripinnated, of a rusty-red co- 

 lour grizzled with white. Foot short, oblong-oval, of a pur- 

 plish-pink colour; sides of under surface veined, and of a 

 pink colour. 



The mantle of this inelegant Doris is not unlike some carbun- 

 cular formation. The under surface is pinkish and shaded with 

 purple. It is a very unsightly object. The edge of the mantle 

 of the young is mottled yellow. The whole animal is nearly 

 5 inches long and 3^ broad in the centre. Ova white, deposited 

 in a narrow tape-like form in four or five broad coils. The 

 white ova alone sufficiently distinguish this ugly Sea-nymph 

 from her rival, D. exanthemata.
