104 Description of New and Little known Species of 



covering the foot; smooth, edge semitransparent, the rest jet 

 black. Branchiae 8 ; small, of a smoky black colour, bipin- 

 nate; two sets of 4 each, all entering the same cavity round 

 anus. Foot long, narrow, rounded in front, slightly project- 

 ing behind, when in progression; of a pale smoky colour. 

 Mouth indistinctly seen. Oral tentacles linear. Dorsal ten- 

 tacles pellucid, with clavate apex; black; tips white, looking 

 like eyes set on the tentacles. Ova white, in 3 or 4 small 

 narrow tape-like coils. 



This species may prove to be either identical with Doris 

 fumata of Leuckart, or D. fumosa of Quoy el Gaym, the lat- 

 ter more probably, as the remarkable, white tipped tentacles 

 (always present), could not have passed unobserved by Ruppel. 

 The branchiae however, of D. fumata would appear to corres- 

 pond with those of the Ceylon species. The next species 

 too, which I regarded at one time as only a variety of D. 

 fumata, must, I think, be considered distinct, as it was not 

 found in April with D. atrata, but subsequently, when the 

 latter became scarce. 



Doris Atroviridis. Kel 



Body 10 lines long, of an invisible green colour. Mantle 

 broad, undulating, of a greenish black colour ; edge streaked 

 with a pale crimson line. Tentacles and branchiae as in 

 D. atrata. Foot of a pale invisible green. Ova like those of 

 the preceding species. Some of the specimens had the mantle 

 indistinctly, but regularly, spotted white ; these spots, composed 

 of several smaller spots round a centre, looked, through a 

 magnifier, like little stars. 



The young of this species is of a jet black colour, with a 

 broad brilliant crimson line round edge of mantle and foot. 

 If I had not specimens of different ages to compare with,
