Tribe Anostraca. 
Family Branchipodidae. 
Genus Podochirus nov. gen. 
The cylindrieal body with eleven pairs of thoracic ambulatory limbs. Ab- 
domen slender and prolonged, distinetly segmented in both sexes, with paired caudal 
appendages and consisting of nine segments besides the caudal rami which are at 
least as long as the three last abdominal segments. 
In most respects this genus closely resembles the genera Chirocephalus, Strep- 
tocephalus and Branchipus. It is, howewer, in the structure of the large frontal 
appendages on the posterior antennae in the male, that the important difference 
exists between the four genera mentioned. The frontal appendages of the right and 
the left are coalesced at the base into a distinct stem inserted on the front of the 
head and very similar to that of Streptocephalus, but the distal part which resem- 
bles that of Chirocephalus except that it has no lamellar process, bears on its outer 
side outgrowths which are arranged like the spines of a comb. 
The ventral egg-sac of the female distinctly sac-formed, directed backwards 
and issuing from the 2 foremost caudal segments. This genus is distinguished from 
Chirocephalus by the width of the egg-sac, which at the base of the free part is 
somewhat thinner than the abdomen at the same height, and is therefore disting- 
uished in this point from Streptocephalus, in which the egg-sac on the mentioned 
place is much thinner than the abdomen.

Habitat. 
This species was found by Dr. MJÖBERG in a »billabong>», in this case a shal- 
low fresh-water pool, in Noonkanbah in Kimberley District of Western Australia on 
the l7th December 1910. The material of this species consists of seven spirit specim- 
ens (5 females and 2 males, of which one is defective). There is a distinct differ- 
ence in size between the sexes. 
Description of the female. 
First pair of antennae small, filiformed and reaching about the posterior margin 
of the eyes, of about the same length as the second antennae. These are rather 
long, uniramous, unjointed, flap-shaped triangular plates.
