Cyprididæ here treated off, having been taken by Mr. White- 

 legge from waterholes at Bourke Street. A sample taken 

 from the same place, also contained numerous well preserved 

 specimens.

 N. Zeal. p. 20, PI. IV, figs. 3, a— d. 



As above stated, this form is evidently specifically

This species too, developed in great numbers in my 

 aquaria, and could at once be distinguished from the pre- 

 ceding one by its more tumid shell, and more uniform 

 colouring. It was also found in the sample sent by Mr. 

 Whitelegge. 



Distribution. — NewZealand, Knysna, China (G.O. Sars). 



Gen. Candonopsis, Vavra.

Specific Characters. — Shell much compressed, and 

 of slightly different shape in the 2 sexes, being, however, in 

 both, when seen laterally, more or less oblong reniform, with 

 the hind extremity rounded and broader than the anterior; 

 ventral margin distinctly sinuated, the sinus in female being 

 median, in male, occurring somewhat in front of the middle,
