No. 9,-1856=8.] CEYLON nudibranchiata, &c. 



89 



internal prolongations of the same colour ; those on sides, 

 longer, alternated with short ones. Branchial plumes 7 or 8, 

 black ; lanceolate, pinnated, few branched at tip. Dorsal tentacles 

 oblong, flattened, pointed ; apex black, lamellated. Oral 

 tentacles small, acutely pointed. Foot white, narrow, slightly 

 dilated in front, and pointed posteriorly. 



Found on coral rocks at low water mark, in August and 

 September. This singularly marked species looks, when the 

 tentacles and branchiae are retracted, like a large bean. Its 

 jet black plumes and tentacles appear very conspicuous above 

 the red margined white mantle. It is very tenacious of life. 

 Ova deposited in narrow white coils. 



Doris preciosa. Kel. 

 Body white, § inch long. Mantle pale greenish yellow, very 

 light coloured on sides, where there is also a blueish shade ; 

 closely speckled with small reddish-brown spots ; margin 

 marked with a narrow purple red line and a light orange shade. 

 Dorsal tentacles short, with reddish-purple apex, clavate, 

 laminated. Oral tentacles triangular, sharp pointed. Branchiae 

 short, pinnated ; reddish-purple. Foot white, shorter than 

 mantle. 



This gem-like elegant species, is of the same size as D. 

 Fidelis, and not unlike it in appearance. The deep blood-red 

 branchial plumes, and the red margined speckled cloak, 

 sufficiently separate it from the last species. They are both found 

 in the same locality, and at the same time. The characters 

 of the young species are also very marked, as in the adult 

 specimens. 



Doris nivea. Kel. 



Body § inch long, convex, elliptical, snowy white. Mantle 

 coriaceous, granular ; white, occasionally seen speckled 

 indistinctly with small grey spots. The purplish coloured viscera 

 seen through the opaline back. Dorsal tentacles pure white, 

 short, conical, pointed slightly, lamellated at tip. Oral tentacles 

 linear. Branchial plumes 6 or 7, white, bi-pinnate. Foot white, 

 shorter than mantle.
