1886.] ENTOMOSTRACA FROM SOUTH AUSTRALIA. 89 
anterior half marked with a fine reticulated sculpture, colour greenish, 
clouded with bands of a darker shade. Length 5); 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, pl. x. H. 
This is very much like C. viridula, but the height is somewhat 
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 51, of an inch. 
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 sete 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. R. 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 slight 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
