NICHOLLS—COPEPODA FROM SOUTH AUSTRALIA 37 
the exopods of legs two to four are strongly serrate, that of the first leg less so. 
Seta formula: 
endopod. exopod, 
p-l. 0.2.320. 1.1.323. 
p.2. 1.2.321. 1.1.423.

The fifth leg is short, sub-rectangular, not twice as long as wide and with pro- 
bably three setae, only one of which was seen. The caudal rami are less than 
twice as long as wide and about as long as the anal seement. 
The species resembles chelifer in some respects, but is more slender, has the 
second segment of the first antenna free, and lacks the inner setae on the second 
and third segments of the fourth exopod present in that species. The serrations 
on the exopods are also probably more strongly developed.
