On Australian Entomostracans. 63 



of fresh water insects, collected for me by my friend the 

 Eev. A. Stobart, in the vicinity of Moreton Bay. 

 Locality; — Moreton Bay. 



3. C. Bennelong. PL X. A. 



A small species, in form somewhat like carinata, but 

 of equal valves sinuated at its ventral edge ; hairy ; of a 

 greenish colour, darker on the back. The animal is large, 

 as compared with the shell. The setae at the extremity of 

 the rami are very strong. 



Locality ; — pond near Sydney Cove, close to the edge of 

 the Saltwater. 



I have named it after an Australian chief. 



4. C. Clarkii. PI. X. E. 



Shell oval, slightly reniform, the valves very convex, 

 variegated, with brown and a light reddish green in well 

 defined notches of irregular but constant shape ; the eye is 

 yellow, shell punctured, pilose. The male appears to differ 

 from the female only in having large irregular masses of a 

 yellowish substance in the abdomen, together with a consi- 

 derable quantity of red globules, such as are seen in the 

 male Daphnia. 



This species generally prefers small shallow ponds, where 

 it can have plenty of light and heat. It is sometimes seen 

 in swarms in the soft mud at the edge of the water, when 

 a pond is drying up. 



I have named it after my friend the Eev. W. B. Clarke. 

 It is one of the most beautifully- coloured of all our Cyprides. 



Locality ; — Sydney : Parramatta. 



5. C. Scottii. PI. X. C. 



In shape somewhat like C. Clarkii, but higher in the 

 back. It is much larger, (being nearly the tenth of an inch 

 in length), of a transparent green colour; the shell marked 

 with very minute reddish spots. It is thinly pilose. 



It is readily distinguished from all the Austrahan species
