In peraeopod 4, article 6 is much longer than 5 in Haswell's drawings, 

 while in the present material article 6 is much shorter than 5. 

 Peraeopod 5, article 2 has crenulations extending in a semicircle 

 from the middle of the hind margin onto the entire lower edge.

with 4 small spines along middle of upper edge. Inner ramus with 2 

 small spines along middle of upper edge. 



Uropod 2: peduncle with 2 small spines on dorsal edge and one 

 at distal end. Outer ramus with one small spine in middle of upper 

 edge. Inner ramus with 2 small spines in middle of upper edge. 



Table 12 gives the relative lengths of the several articles of the 

 three pairs of uropods. The apical tips of the rami are nonmovable 

 chitin. 



Third epimeron: rounded behind and minutely dentated, lower 

 posterior corner bears a very small tooth. 



Remarks. — The specimens obviously are different from other 

 Australian species such as P. villosus, P. pinguis, P. australis, and 

 P. rostratus and probably represent a new species. Phoxus batei, as a 

 specific category, has been fused with P. rostratus (Dana).
