114 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Chelipeds and legs clothed with long hair, through 

 which the surface is imperfectly seen ; arm with a large, 

 subterminal tooth above, lower and inner margins tuber- 

 culated ; carpus finely and sparingly granulate, a small 

 tooth at inner angle ; larger palm unevenly tuberculate, the 

 tubercles largest on upper surface and on lower, distal 

 portion of outer surface; proximal half of lower margin 

 tuberculate ; fingers smooth except upper, proximal end of 

 dactylus ; two grooves on outer surface of fixed finger, 

 which is slightly deflexed. Minor palm considerably 

 smaller, tuberculation continued so as to embrace the w r hole 

 lower surface, and part of the fingers, each finger -with 

 three deep grooves on the exposed surfaces. Legs almost 

 entire, the upper margin of the merus finely and obscurely 

 roughened. 



Remarks. In shape this resembles some species of 

 Heter&panope Stimpson. :o Of the species of Pilummis, it 

 has much in common with P. marginal us Stinipson 11 from 

 Loo Choo, but the carapace of the latter is wider with more 

 convergent postero-lateral borders and the hands are more 

 finely roughened. 



In P. contrarius the tubercles of the major palm, con- 

 trary to the customary rule, increase, instead of diminish, 

 in size toward the distal, lower portion, a fact to which the 

 name draws attention.
