CYPRIS, Muller, &c 
(Cl, Crustacea. Sect . Branchiopoda.) 
Gen. Char. Animal inclosed within two oblong 
crustaceous shells ; antennae two, straight, sim- 
ple, terminated by a brush of hairs ; one eye ; 
four legs ; the head concealed ; tail small. 
Minute 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 Linnaeus, chiefly 
by the oblong form of the shells, the simple antennae, 
, and the number of the legs. In the nearest genus (Cy- 
therina) the legs are eight, and the antennae 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.
