On Fresh-water Entomostraca. )jl 



St. Leonard's; South Creek; Denham Court. To these local- 

 ities may now be added the followings: Waterloo Swamps; 

 pond opposite Lachlan Street; off Botany Road, near Water- 

 works Bridge. 



In all probability, the species is distributed all over 

 Europe, Asia, Africa and America, being a true cosmopolite.

Chydorus augustus, King, 1. c. p. 258, Pl. VII B. 



There cannot, I believe, be any doubt that this is the 

 true Chydorus augustus of King. This form however, as 

 shown by the figures given on the accompanying plate, is 

 undistinguishable from the well-known European species 

 C. globosus of Baird, and, as the name given by Baird is 

 much the older of the two, it ought to be retained for the 

 species. The solitary specimen here figured, which measured 

 0,65 mm. in length, was found in a sample from the Centennial 

 Park. Mr. King collected the species from a pond on the 

 Road to Botany Bay. 



Gen. Pleuroxus, Baird. 



11. Pleuroxus in er m is, G. O. Sars, n. sp. 

 (PI. 5, figs. 8, 9). 



Specific Characters. — Y Shell, seen laterally, of an 

 irregularly rounded form, and narrowly truncated posteriorly, 

 dorsal margin boldly curved, ventral somewhat protuberant 

 in front, and nearly straight behind, infero-posteal corners
