Occurrence. South of Eucla, Great Australian 

 Bright, long. 129 28' E., 250450 fathoms, type locality; 

 four males and four ovigerous females (Reg. Nos. E.3681, 

 E. 6631, E.6632, E.6633, E.6634 and E.6635) ; E.3681 is 

 the female holotype. 



S.W. of Eucla, Great Australian Bight, long. 126 

 45-25' E., 190-320 fathoms; one male (Reg. No. E.3692). 



S.E. of Eucla, Great Australian Bight, long. 130 50' 

 E., 250-300 fathoms; t\vo ovigerous females (Reg. No. 

 E.3687).

Description. With respect to the shape and toothing 

 of the rostrum, the configuration of the carapace and the 

 form of the autennal scale, the species stands near Bate's 

 C. semistriatus. 60 From the latter, however, it is strik- 

 ingly distinguished by the prominent, dorsally flattened 

 tubercle on the middle of the third abdominal somite, and 

 the prominent compressed spines projecting backward 

 from the posterior median border of the third, fourth and 

 fifth somites. 



The carapace is about as long as the first two, 

 and half the third somite of the abdomen taken together. 

 Dorsaliy it is carinated to within a short distance of the
