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



Doris intecta, Kel. 



Body l:j 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 mouths of September and October. 



Doris lanuginosa, Kel. 



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

 with short downy hair. Dorsal tentacles gi'een, lamellated, 

 pubescent. Oral tentacles not observed. Branchias 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. 



Doins spongiosa, Kel. 



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

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

 colour, deejjly 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 wa^y 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.
