Mandibles, cutting-edge 4-dentate in left, 5 in right, secondary 

 cutting-edge in left 4-deutate, in right represented by a stout spiuiform 

 process, spine-row with 7-8 spines, molar minutely denticulate, palp 

 very large, 2nd joint twice length of 1st, 3rd not quite as long as 2nd, 

 not enlarged but apical ly obtuse, setose. 



First maxilla, inner plate with 4 setae, outer plate with 11 spines, 

 2nd joint of palp elongate. 



Second maxilla with inner margin of inner plate setose. 



Maxilliped as in C. australis Stebb. 



First guathopod similar in both sexes, 6th joint not quite as long 

 as 5th, ovate, palm slightly convex, passing uninterruptedly into 

 hind margin, finger matching palm, 5th joint more strongly setose 

 than 6th. 



Second guathopod in $ , 2nd joint with a small tooth on anterior 

 apex, 5th well marked off from 6th inferiorly, but not so well on 

 anterior margin, 6th large, ovate, palm a little oblique, longer than 

 hind margin, with 2 strong pointed teeth, that near the hinge being 

 apically bifid, defining angle also with a strong pointed tooth, finger 

 as long as palm, smooth, distally rather strongly curved. In $ 

 smaller, 2nd joint without tooth on anterior apex, 6th not quite as 

 long as 2nd, ovate, narrowing distally, palm, more oblique than in <$ , 

 creuulate, with a blunt tooth, bearing 1 spine in the middle and 

 another near the hinge, defining angle with a small acute tooth, 

 finger matching palm, not strongly curved. 



First and second peraeopods, 4th joint somewhat enlarged, 6th 

 longer than 4th, 7th half length of sixth. 



Third to fifth peraeopods increasing in length, 2nd joint broadly 

 ovate, hind margin entire, with fairly numerous plumose setae, 

 anterior margin also setose, especially when near the apex, but setae 

 simple. 



First and second uropods with peduncle longer than rami in 1st, 

 only a little longer in 2nd, rami of both subequal. 



Third uropod, peduncle stout, outer ramus subequal to peduncle in 

 length but considerably narrower, apically spiuulose, a 2nd joint not 

 distinguishable, inner ramus minute, tipped with 1 spinule. 



Length : 5 mm. 



Colour : White, head yellowish, 4th and 7th peraeou segments and
