CYPRID.E. 
139 
Family I — CYPRIDiE. 
Cypris, Muller , et auctorum . 
Cyproides (pars), M. Edwards, Hist. Nat. Crust., iii, 393. 
Cyprid^e (pars), Baird, Trans. Berw. Nat. Club, ii, 153. 
Character . — Two pairs of antennae ; superior long, with 
numerous joints, and a pencil of long filaments ; inferior 
stout and pediform. Eye single. Feet two pairs. 
Bibliographical History . — Baker is said to be the first 
author who has taken any notice of any of the animals of 
this family. In his work, ‘Employment for the Micro- 
scope/ 1753, an anonymous correspondent describes at 
some length an insect which has a bivalve shell, somewhat 
resembling a small fresh-water mussel, and gives a figure 
of it lying on its back, which is barely sufficient to enable 
us to discern that it is a Cypris. 
Straus complains that he cannot discover any mention 
made of the genus by Baker, either in the edition of 
1743 or 1744, which are the only editions he has been 
able to see ; neither is there, he says, any plate 1 5 in either 
of these editions. He quotes the wrong work, however, 
having referred to the ‘ Microscope made Easy/ instead 
of Baker’s second work, ‘ Employment for the Micro- 
scope’, in which he would have found the insect referred 
to by Muller. 
Linnaeus, in his ‘Fauna Suecica,’ 1746, describes a 
species in a few general terms; and, in the seventh 
edition of the ‘ Systemae Natura/ 1748, he mentions a 
species under the name of Monoculus concha pedata , but 
gives no description. In the tenth edition of the same 
work, 1760, he gives the description, as taken from the 
£ Fauna Suecica,’ but names it Monoculus conchaceus. 
Joblot, in his ‘ Observations d’Histoire Naturelle faites 
avec le Microscope,’ 1754, describes a species, which he 
calls poisson nomine Detouche, or Grain de Millet, from 
its resemblance in size and colour to that species of seed, 
and gives a figure of it.
