found in New South Wales. R49 
it will remain for a considerable time. The anterior branch 
of the inferior antennz is generally kept in a curved 
position when the animal is at rest. 
I have named the species after Miss King, of whose kind 
assistance in my search for Entomostraca the discovery of 
this species was the first fruit. Localities :—This species 
is widely distributed ;—I have found it at Sydney, New 
Town, Parramatta, the Cowpastures, and in the River 
Karuah, near Stroud, Port Stephens. 
(3.) Daphnia honorata. (Plate III).—Carapace oblong, 
dorsal margin often concave, the surface reticulated in an 
irregular pentagonal manner. The spine at the extremity 
is very short. 
Superior antenne large. Inferior also large, the basilar 
joint having a crenation carrying two sete. ‘The first joint 
of the posterior branch is as long as the remaining two, 
and as long also as the first three of the anterior branch. 
Sete not plumose. 
The sixth segment of the oak has one small process, 
directed backwards. The segment itself is large, and much 
resembles the corresponding part in many of the Lynceide. 
The proportions of the joints of its inferior antennz 
readily distinguish it from D. reticulata and D. rotunda 
(Barrp), which it very much resembles. 
Male unknown. Locality :—I have hitherto only found 
this interesting species in one locality,—a small pond in the 
gardens at Varroville, near Campbell Town.

Genus Mona. (Baird.) 
Head obtuse; not produced into a beak. Superior 
antenne of considerable length; one jointed, arising from
