6 Cypridina. — Two eyes and two pairs of 

 feet. Appears to me to form a connecting link between the 

 OsTKACODA and the Lynceid^e ; its peculiar terminal seg- 

 ment of the abdomen, as well as its rami, being closely 

 analogous with those of many of the Cladocera. *' 



There are three genera belonging to the family Cypridse 

 in Australia. 



Cypris; — (Muller), rami provided with a pencil of long 

 setse ; animal swimming, partly on its ventral edge ; eye 

 single. 



Candona; — (Baird), rami destitute of the long setse ; 

 amimal creeping on the ground or on plants ; eye single. 



Newnliamia ; — nov. gen., rami as in Cypris; animal 

 swimming freely through the water on its back ; eyes two. 



Genus I. Cypris. 

 1. Cypris cari7iata, PI. IX. 0. 1-4. 



Shell nearly elliptical, but higher on the back ; the valves 

 are unequal, the right being produced beyond the left at the 



* Professor M'Coy, in his late work on the " British Palseozoic Eock Sand 

 Fossils,'' has expressed his opinion that " all the Cytherece of Palseozoic 

 rocks are more properly Phyllopoda than Lophyropoda." I confess that the 

 analogy of these fossils with the latter, through the recent species of 

 Cythereis, appears to me to be almost established by the discovery of 

 Newnliamia,
