considerably more than half of its lateral margins is set with spines; in both sexes the telson 

 has only a single pair of spines on its widened basal portion, behind these spines the telson 

 is feebly or scarcely constricted, and its end bears a single pair of very long spines, while its 

 usual three spines between this long pair are short though scarcely or slightly shorter than the 

 pair outside the long spines; in the male the lateral spines along almost the distal half increase 

 regularly but feebly in length backwards, constituting a rather close row; in the female only 

 the 5 or 6 distal spines increase regularly in length, while the remaining 2 or 3 spines are 

 irregular both as to length and the intervals between them. 



Length of a male 6.6 mm., of a female with marsupium 5.1 mm. 



Remarks. ■ — ■ The female of this species is easily separated from all other forms by 

 the dorsal protuberances on the carapace ; both sexes are distinguished by the enormous length 

 of the legs of third pair as compared with those of first pair or with the gnathopods ; telson 

 and uropods afford other valuable characters.
