the 1st antennae. Frontal lamina meeting the rostrum, about as 

 broad as long, anterior margin obtusely pointed, a prominent and 

 outstanding transverse ridge across the middle, but not produced into 

 a horn. 



Peraeon and pleon segments not denticulate on posterior margin. 

 Fifth pleon segment without free margins. 



Telson a little longer than broad, triangular, lateral margins 

 straight, apex subacute, with 8 short, stout spines and a few plumose 

 setae. 



Antenna 1 reaching to end of peduncle of antenna 2, flagellum 

 13-jointed. 



Antenna 2 reaching to 3rd peraeon segment, flagellum 26- 

 jointed. 



Mouth -parts normal. 



Peraeopod 1, 3rd joint with 1 spine on inner margin, 4th with 6 

 stout apically truncate spines on inner margin, inner apex of 5th with 

 1 spine-seta set between 2 tubercles, 6th with 4 spines alternating 

 with small rounded tubercles. 



Peraeopod 2, 3rd joint with 3 apical and 2 smaller subapical spines 

 on inner margin, outer apex bluntly produced, with 3 stout spine- 

 setae, 4th with 9-10 stout blunt spines on inner margin, outer apex 

 with 1 spine, inner apex of 5th with 3 spines and a tubercle below 

 them, inner margin of 6th with 4 spines alternating with 4 small 

 rounded tubercles. 



The other peraeopods moderately slender, 2nd joint of 5th-7th 

 peraeopods not expanded or furnished with long setae. 



Uropod, inner ramus reaching apex of telson, distal margin with a 

 few short plumose setae and 8 stout spines, apex subacute, outer 

 distal margin with a few short plumose setae and 3 spines, outer 

 ramus a little shorter, ovate, apex bifid, outer margin with 6 stout 

 spines, inner distal margin with 4 stout spines and some plumose 

 setae, inner apex _of peduncle reaching half-way along inner 

 ramus. 



Length : 12-13 mm. ; breadth : 4 mm. 



Colour : Yellowish-white speckled with dark grey, eyes black. 

 Locality: Saldanha Bay. 5/9/12. (K.H.B.) 1 specimen; Dyer's 

 Island. April, 1915. (J. Drury.) 1 adult and 1 juv. (S.A.M. 

 Nos. A2465 and A3383.) 



In the shape of the frontal lamina this species closely resembles 

 C. schiodtei Miers, 1884, from the Arafura Sea, but lacks the two 

 setose tracts on the telson which are so conspicuous in Miers 1 figure, 

 although not mentioned in his description.
