like lines on the margin. I have only seen one specimen, 

 which lived for a few days. 



Doris Marmorata. Kel. 



Body inches long, oblong, convex, coriaceous; white, 

 speckled reddish brown, Mantle broad and long, covering 

 the foot; thick, hard, granular; marbled with black and red- 

 dish brown, and irregularly spotted white. Under surface 

 white, and mottled with irregular shaped purplish red spots. 

 Branchial plumes 6, united at base, superior half plumose, 

 tripinnated, grey and grizzled with brown. Dorsal tentacles 

 large, clavate, laminated ; brown and speckled white. Sheaths 

 granular. Head small ; oral tentacles long, linear, acutely 

 pointed. Foot white, deeply notched and grooved in front ; 

 spotted reddish brown, 



This large marbled Doris lived only for a few days. They 

 are found on rocks near Fort Fredrick at low water mark. 

 Some are of a darker brown colour than others. 



Doris Cerisa, Kel 



Body J inch long, convex, oval ; of a vermillion red colour. 

 Mantle of a cherry red colour, covering the foot. Branchial 

 plumes 6 or 7; very small, straight and stiff; bipinnated; 

 of a crimson red colour. Dorsal tentacles small, conical, la- 

 mellated, purplish red; speckled white, tip grey. Oral ten- 

 tacles indistinctly seen. Foot pinkish. 



I have only seen one specimen of this exceedingly pretty 

 species. It lived for several months in a finger glass. It 

 cannot be mistaken for the young of any other Ceylon species 

 herein described. Ova red, in 6 narrow tape-like coils. The 

 ova of D. rubra (inihi) are white.
