96 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Chelipeds of female shorter than of male, as figured by 

 Baker, the merus scarcely reaching beyond the lateral angle 

 of the carapace. The merus has a spine instead of a 

 tubercle on its upper margin. The major chela, in this case 

 on the right side, has an enlarged tooth at the base of the 

 dactylus, which is absent from the slightly smaller, minor 

 chela. The first three pairs of ambulatory legs are longer 

 than the chelipeds. 



This species was accidentally omitted from the report on 

 spider crabs, vol. v., part 1, of this series, on account of 

 its strong resemblance to Telmessus, save for the arrange- 

 ment of the basal antennal segment.
