found in New South Wales. ay 
The male is much smaller than the female, and the shell 
narrower. ‘The superior antennz are large, springing from 
under the beak, ending in one long stout-jointed seta 
and several smaller ones. 
Its habits are not active, consequently it is generally 
covered with vorticellze, which much impede its movements. 
It never clings to the stems of weeds, or the side of the 
vessel in which it is kept, as the next species does. 
Var. B.—I have only noticed, and that rarely, in the 
swamps connected with Botany Bay. I have not seen it 
with ova or ephippia. I have almost doubted whether it 
is not entitled to be regarded as a different species. 
Var. C.—Is remarkable for the number of its eggs. 
The specimen figured had between 70 and 80. It was 
found in a small ditch near Sydney, associated with a 
multitude of Cyclops. Localities :—Ponds near Sydney, 
Parramatta, Campbelltown, &c. 
(2.) Daphnia Elizabethe. (Plate I1.)—Carapace oblong 
(in gravid females ovate); obliquely striated, the striz 
sometimes anastomozing, but seldom, if ever, crossing. 
The inter-spaces are punctured irregularly, anterior margin 
ciliated; spine none. 
The head is obtuse; beak short, a black spot close to 
the beak. Superior antennz large, consisting of a stout- 
curved joint (which is articulated to the base of the 
beak ?*) From its extremity eight or nine sete spring; an 
additional seta is placed on a short process near the base. 
The filaments of the superior antenne are jointed and 
thinly plumose. A short spine rises from the extremity 
of the second joint of the anterior branch. The basilar 
* I put a query to this, because I have not seen the joint moved, although 
I have no doubt that it does move.
