Neiu Victorian Fresh-ivater A7)iphipoda. 49 



evenly rounded lobe bearing about eight stout faintly feathered 

 setae ; propodus a little longer than carpus, subtrigonal, 

 widening distally, anterior margin strongly curved, palm nearly 

 transverse, slightly convex and entire, meeting the posterior 

 margin in an evenly rounded narrow curve bearing a little spine, 

 posterior margin a little convex and free from setae. Second 

 gnathopoda with propodus normally large, almost as broad as 

 long, posterior margin equalling half the length of the anterior, 

 both nearly straight, palm transverse, convex and setose, detined 

 by a small rounded tubercle. Dactylus of equal length to the 

 palm, inner margin entire, and on the outer margin a plumose 

 setae. 



First two pairs of pereiopoda equal in length and form, the 

 third also of similar length, fourth longer, fifth of equal length 

 to the fourth. In each of the last three pairs the basos is 

 expanded, the last greatly so, being as wide as its length, with the 

 hind margin strongly convex and deeply and irregularly serrated. 



Uropods normal to the genus, terminal pair one-jointed. Telson 

 subrectangular, lateral angles rounded, distal margin with a 

 small rounded expansion medianly ; armed distally above, on 

 each side of the median line, with two spinules. 



Female. — Similar in form to the male, except in the second 

 gnathopoda which are, except for being rather longer, like the 

 first pair. 



Colour. — Spirit specimens uniformly yellowish. 



Length. — ? 4 mm. $ rather larger. 



Occurrence. — From Lake Hindmarsh, North- Western Victoria 

 (received from Professor Baldwin Spencer). 



Rejnarks. — This species is easily distinguished from the New 

 Zealand C. mihiwaka, by the much more slender body, and the 

 larger head and eyes ; and from C. australis, by the shorter 

 urosome, one-jointed terminal uropoda, shape of the hands, and 

 much shorter antennae. Amongst about twenty specimens there- 

 were only two males. 



Atyloides fontana, sp. nov. (PI. V.). 



In general appearance very like A. gabrieli, but with deeper 

 side-plates, the antennae not bearing fascicles of long setae, and
