anterior half marked with a fine reticulated sculpture, colour greenish, 

 clouded with bands of a darker shade. Length g-^ of an inch. 



Collected by Mr. Thomas Steel at Condong, on the Tweed River, 

 near Sydney, New South Wales. 



2. Cypris stanleyana (King). (Plate VIII. figs. 3, 4.) 

 Candona stanleyana. King, 1855, Pap. Proc. R. Soc. Van Die- 

 men's Land, vol. iii. pt. 1, p. 66, pi. x. H. 



This is very much like C. viridula, but the height is somevt^hat 

 less, the dorsum is more decidedly arched, and the extremities are 

 less obliquely rounded. The surface is marked everywhere with fine, 

 very closely set, and deep longitudinal grooves. Colour light green, 

 slightly clouded. Length gV of ^^^ \\ic\\. 



Taken in the same gathering as the preceding species. Mr. King 

 refers this to the genus Candona ; but the lower antenna is provided 

 with a brush of setae reaching about to the extremity of the terminal 

 claws. 



3. Cypris tatei, n. sp. (Plate VIII. figs. 5, 6.) 



Shell, seen from the side, broadly reniform, greatest height in the 

 middle, and equal to more than half the length ; extremities rounded, 

 dorsal margin boldly arched, sloping abruptly behind, more gradually 

 towards the front, ventral deeply sinuated in the middle ; seen from 

 above, the outline is ovate, somewhat compressed in front, widest 

 behind the middle, anterior extremity subacuminate ; posterior wide 

 and rounded ; valves unequal, that of the right side the larger. 

 Surface smooth, colour yellowish brown, with darker clouded 

 markings. Length -^-^ of an inch. 



Taken by Prof. 11. Tate in "brackish pools in a dry creek at 

 Adelaide." 



This species, though considerably more tumid, has very much the 

 general character of C. prasina, Fischer {fretensis, Brady & Robert- 

 son), and of C. incongruens, Ramdohr, especially as to the curiously 

 compressed anterior extremity. It is remarkable, too, that all of 

 these are inhabitants, almost exclusively, of brackish water. I have 

 pleasure in naming the species after Prof. Ralph Tate, by whom it 

 was found, and to whose kindness I am indebted for the opportunity 

 of describing it. 



4. Cypris mytiloides, n. sp. (Plate IX. figs. 1-3.) 



Shell, seen laterally, elongated, siliquose, highest in front, pro- 

 duced behind into a very acute, tapering beak ; height equal to less 

 than one half the length ; anterior extremity broad and boldly 

 rounded, dorsal margin boldly arched, highest near the front, thence 

 sloping at first with a gentle'curve, but more abruptly towards the 

 posterior extremity, in front of which it is deeply sinuated ; ventral 

 margin almost straight, with a shght median sinuation ; seen from 

 above, compressed, oblong, widest near the middle, about thrice and 

 a half as long as broad ; extremities acute, the posterior the more
