This snowy white opaline Doris, is probably only a variety 

 of Doris pallida of Leuckart, found by Ruppel in the Red 

 Sea. It has not, however, all its characters ; the cloak resembles 

 that of D. repanda in some respects. It has white, nerve-like 

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

 lived for a few days. 



Doris marmorata. Kel. 



Body 2J inches long, oblong, convex, coriaceous ; white, 

 speckled reddish-brown. Mantle broad and long, covering 

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

 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, tri-pinnated, 

 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 Frederick 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 ; bi-pinnated ; of a 

 criinson-red colour. Dorsal tentacles small, conical, lamellated, 

 purplish red ; speckled white, tip grey. Oral tentacles 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 six narrow tape-like coils. The 

 ova of D. rubra Qriihi) are white.
