Chelipedes slightly pubescent. Eight wrist broad and 

 armed with spiny tubercles, the hand broadly ovate, with 

 three longitudinal carinse on the upper surface (the two 

 marginal dentate, the central more obtuse). The intervals 

 between these carinas somewhat hollowed out and granu- 

 lated. Hand of the left chelipede hairy, with a median 

 carina on the upper surface. Length, 2 inches. 



Hcib. — Shetland in deep water (Norman) ; off the west 

 coast of Ireland, 100-169 fathoms (" Porcupine " Exped.) ;

 characterised by the greater development of spines on the carinse of the right 

 hand.
