CYPRIS, Miiller, &c 



{CI. Crustacea. Sect. Branchiopoda.) 



Gen. Char. Animal inclosed within two oblong- 

 crustaceous shells; antennas two^ straight^ sim- 

 ple^ terminated by a brush of hairs ; one eye ; 

 I four legs ; the head concealed ; tail small. 



JMiNUTE crustaceous animals, whose body is inclosed 

 within a pair of shell-like valves, and which possess the 

 characters above given, form this genus. It is distin- 

 guished from one or two analogous ones, which were 

 arranged with it under Monoculus by Linnajus, chiefly 

 by the oblong form of the shells, the simple antennaB, 

 and the number of the legs. In the nearest genus (Cy- 

 theriua) the legs are eight, and the antennse are pilose 

 for their whole length ; there is no tail ; and the shells 

 are more distinctly reniform. The Cytherina is an in- 

 habitant of the sea, while Cypris has only been found in 

 fresh-water.
