302 Dr. E. F. Kelaart on new species oj Ceylonese Molluscd, 



Doris intecta, Kel. 



Body IJ inch long. Mantle warty, of a dark brown colour, 

 nearly black ; on the medial line is a thick white pasty line. 

 Dorsal tentacles brown, clavate, laminated. Oral tentacles 

 long, linear, pointed, of a bright brown colour. Branchial 

 plumes six, tripinnated, of a golden-brown colour. Foot 

 golden brown, narrow, longer than mantle. 



This warty Doris is easily distinguished from others of a brown 

 colour by its rufous warty mantle and the dirty-white line on 

 the back. Even the young have the white dorsal streak. Very 

 common at low-water in the months of September and October. 



Doris lanuginosa, Kel. 



Body J inch long, of a pale green colour. Mantle green, covered 

 with short downy hair. Dorsal tentacles green, lamellated, 

 pubescent. Oral tentacles not observed. Brauchise ten or 

 twelve, small, of a sap-green colour, bipinnated. Foot shorter 

 than mantle, of a pale-green colour, transparent. 



Of this downy species I have only seen one specimen; it 

 lived only a few days. Found near Nicholson's Cove. 



Doris spongiosa, Kel. 



Semigelatinous. Body nearly 3i inches long. Mantle broad, 

 . oval, covering the foot in all parts, of a dull yellow-brown 

 colour, deeply pitted ; margin of pits granular, cavities spon- 

 giose. The whole upper surface of the mantle looks like 

 the surface of some species of sponge ; beneath of a darker 

 . yellow-brown colour. Dorsal tentacles large, with slightly 

 truncated laminated apex; sheaths large, funnel-shaped, gra- 

 nular. Oral tentacles (?). Branchial plumes five, grey, 

 drooping much, bipinnated. Foot broad, long. 



This very curiously-formed Doris is found in deep water in 

 the Inner Harbour. The young may be mistaken for a distinct 

 species, from the lateral cavities or pits being deeper. The whole 

 animal is nearly the size of Doris exanthemata, 



Doris striata, Kel. 



Coriaceous. Body 1| inch long. Mantle nearly smooth, white, 

 with light-brown wavy streaks. Under surface white, with 

 linear wavy streaks near the body. Dorsal tentacles with 

 short, conical, laminated apex. Oral tentacles white, linear, 

 pointed. Branchial plumes five or six, small, bipinnated, 

 white streaked with brown. Foot pure white, narrow, oblong. 



Found in Dutch Bay.
