INDIAN NUDIBRANCHIATE MOLLUSCA. 131 



GONIODORIS ASPERSA, D. Sp. (PI. XXXIII. fig. 2.) 



Body elongated, densely and minutely freckled with dark chocolate-brown. Cloak 

 oblong or subquadrate, with the margin slightly sinuated and turned up at the sides, 

 and also in front, where it is bent back in a rounded lobe ; the posterior end bending 

 inwards behind the branchiae : the cloak is densely freckled like the rest of the body, 

 having an irregular pale line running down each side : the margin is also pale, with a 

 few black and yellow spots ; and an irregular line of light spots runs along each side of 

 the body below the pallial margin. An obtuse carinated ridge reaches from the mantle 

 to the tail. Dorsal tentacles clavate and laminated, freckled with the same dark colour 

 as the body. Branchial plumes five, small, twice or thrice pinnated, and placed a little 

 apart from each other and from the anal nipple ; they are darkly freckled above, with 

 yellow tips; the under surface pale. Head squared in front and produced considerably 

 beyond the cloak, the sides forming two moderate-sized tentacular processes held 

 laterally. Foot yellowish, without markings, truncated in front, and rather narrow, 

 with the sides almost parallel, extending beyond the cloak for about one-fourth of the 

 whole length of the body, and terminating in a blunt point. Length nearly ^ an inch. 



Tongue minute and like that of G. nodosa, but the sides of the spines are smooth ; 

 there is a buccal collar with rudimentary jaws, as in Doris pilosa. 



Rather rare : two specimens are in the collection. 



GONIODORIS CITRINA, n. sp. (PI. XXXII. figs. 1, 2, 3.) 



Body oblong-ovate, broad in front and tapering to a point behind, lemon-coloured, 

 with the processes tipped with purple-brown. Cloak largely developed, and produced 

 at the sides into about seven rounded lobes reflected upwards and densely freckled with 

 purple-brown ; posteriorly the pallial margin appears to terminate in a well-produced 

 point on each side, but an indistinct ridge converges from thence to a fringed keel 

 tipped with purple-brown, which runs down to the tail : the rest of the cloak is pale 

 lemon-yellow, darker towards the centre, where there is a slightly elevated ridge bearing 

 obtuse points. Dorsal tentacles clavate and strongly laminated ; the laminae and tips 

 of a purple-brown colour. Head not much produced, very broad, with two shortish, 

 flattened tentacular processes, somewhat pointed, and tipped with purple-brown. 

 Branchial plumes five, large, tripinnate, yellow, marked on the under surface with 

 purple-brown, closely surrounding the anus, the two posterior plumes rising from the 

 roots of the lateral pair. Foot broad and ample, of an ovate form, truncated in front, 

 and produced into a point behind. Length upwards of an inch. 



Tongue as in G. nodosa, very minute ; the sides of the spines are extremely minutely 

 denticulated : no spinous collar was observed. 



Tolerably frequent. Only one specimen preserved.
