of the inner margin and not reaching to the posterior margin ; 

 endopod very small and short, almost knob-like, reaching only 

 a very slight distance beyond the base. 



Colour. — DaTk slatish with light-brown markings along 

 the lateral and hind margins of the segments. 



Length. — About 15 mm. 



Remarks . — I describe this species with considerable hesi- 

 tation. In general size, surface of body, etc., it resembles 

 C. montivagus (Budde-Lund), which is found in the Samoan 

 Islands, but it differs markedly from that species in colour, 

 in having the epimeron of the first segment curving outwards 

 anteriorly, and in having the inner lobe of the split margin 

 the smaller instead of being the larger, as in C. montivagus.

Loos. — Clayton Creek, 5 specimens : Cooper Creek, 1 

 specimen. 



I have little doubt that these specimens belong to the 

 species named above, which is the only species of the genus 

 yet known from Australia. According to Spencer and Hall, 

 specimens from many widely-separated parts all belong to 

 this species. Sayce gives as the distribution: "Western Aus- 

 tralia, South Australia, northern areas of New South Wales, 

 and northern areas of Victoria." 



In the general dimensions and proportions the specimens 

 agree well with the description given by Spencer and Hall in 

 their report on the Crustacea of the Horn Expedition, though 

 according to them there are variations in the dimensions of 

 considerable extent. Similarly the number of spines on the 

 different segments show slight differences from their descrip- 

 tion, but the only difference of any importance I have noticed 

 is that in the specimens I have examined the carina on the 

 carapace is smooth and does not end posteriorly in a spine ; 

 Spencer and Hall describe the carina as being '"minutely and 

 irregularlv serrated and ending in a spine posteriorly." 



The colour of the specimens examined is olive-green 

 tending to brown at the edges, along the carina, etc.
