PsEUDOCYCLOPS AUSTRALIS sp. nov. 
Occurrence. XIII, 1 female, 1 juvenile. 
Female. Length 0:78 mm. The body is of similar proportions to obtusatus; 
the urosome is 4-segmented, the anal segment being very short and partly tele- 
scoped into the pre-anal; the caudal rami are as long as wide, and somewhat di- 
vergent. The first antenna has eighteen segments and the second antenna has 
the end portion distinctly cut off as a separate segment. The mouth parts are 
much as in obtusatus. The middle segment of the endopod of the first leg has an 
elongate bulbous process distal to the outer spine. In the fifth leg both the first 
and second segments of the endopod have their outer distal corners produced into 
processes, that on the first segment being very pronounced and bearing a small 
seta; the end segment, has several distal processes, two of which are large, and 
bears four setae. The seta formula is as follows: 
endopod. exopod.

The species is not unlike simplex but differs in the armature of the swimming 
legs and in the caudal rami.

Occurrence. I, 3 females, 1 male; IT, 7 females, 5 males, 2 juveniles; III, 1 
female ; IV, 8 females, 4 males; V, 2 juveniles ?; Vil, 1 female; IX, 1 female; XIV, 
2 females, 1 male. 
Distribution. Malay Archipelago, Southern Burma, Ceylon Pearl Banks, ‘‘In- 
vestigator’’ Stations 587, 614. 
With the exception of the ‘‘Investigator’’ collections all of the places where 
this species has been taken are coastal, usually quite close to the shore, often hav- 
ing been taken while the vessel was at anchor. In the case of the exceptions men- 
tioned I have been unable to trace the localities of these stations, but from the re- 
marks made by Sewell (1929, p. 2) it would appear at least probable that these 
stations fall into line with the above. The species must, therefore, be regarded as 
a coastal form and it is interesting to find it in the present collections, which are 
all taken from the western shores of South Australia. Furthermore, although the 
genus is represented in the waters of New South Wales (Dakin and Colefax, 1940, 
p. 105) this species has not been recorded from that region.
