114 Description of New and Little known Species of 



naming this genus, closely allied to Grlaucus, if new, in honor 

 of Dr. Tenipleton, late of the Royal Artillery (brother of the 

 Belfast Naturalist) who has contributed considerably to the 

 Fauna of Ceylon. 



I have found only one specimen, on a branch of sea weed. 

 It looked at first like a piece of green weed, but on placing 

 it in fresh sea water, the lobes expanded and waved about 

 very briskly. The red tips of the lobes contrasted beauti- 

 fully with the bright green of the animal. It lived only a 

 few hours. 



POLYCERA (?) CeYLOXICA. Kel 



Body J inch long. ISFo distinct mantle. Head covered by 

 a membranous fimbriated veil ; the long filaments slightly 

 toothed. Veil continuous with a narrow membranous expan- 

 sion on side of body, which are united at the tail. Large 

 fimbriated filaments also on sides of body. A membranous 

 crest runs on the medial line of back. Dorsal tentacles re- 

 tractile in a sheath ; clavate, laminated, incurved at the tip : 

 brown, white tipped. Oral tentacles white ; broad and short. 

 Branchial plumes 5, short, bipinnated, retractile, placed in a 

 circle, in the centre of the back, near the third pair of dorsal 

 filaments. Colour above, bright orange red ; beneath whit- 

 ish, with red specks seen through the transparent foot. Ova, 

 bright red ; in narrow coils. The whole animal is scarcely 

 one inch long ; and its broadest part not more than f of 

 an inch. 



I have placed this species, very doubtfully, under the head 

 of Pctycera. I believe there is sufficient reason to make a 

 new genus of the leading characters of this pretty little 

 creature. The transparent membranous expansion is fully 

 extended when the animal swims, which it does, more freely
