developed as in the Pacific species, the whole outer face of the immov- 

 able fino'er is strongly tuberculated, the teeth of the lower margin are not 

 expanded into conspicuous plates, and the inner face of the chela is nearly 

 smooth. The carpus in P. hiriimanus is armed with larger spines on the 

 internal margin, is more hairy, and more coarsely granulated on its inner, 

 inferior, and outer surfaces than it is in P. rosaceus. The left chela is com- 

 paratively smaller than in P. rosacem, is more strongly toothed along the 

 internal margin of the propodite and dactylus, and exhibits, besides, most of 

 the above-specified peculiarities of the right claw. The primary branch of 

 the unpaired abdominal appendages is shorter and broader than in P. rosa- 

 ceus. The rasp on the propodus of the fourth pair of legs is uniserial as in 

 P. rosaceus. 



Length of carapace of largest male, 12 mm. ; length of cai-apace in front 

 of cervical groove, 7 ram.; breadth across the branchial regions, 9.5 mm.; 

 length of large claw, 1 1 mm. ; breadth of large claw, 7 mm.

A good deal of the color is still preserved in alcohol. The lower surface 

 of the eye-stalk is quite a deep red, while the upper surface is a pale yellow. 

 The merus and carpus of the chelipeds and all the segments of the ambula- 

 tory legs from the ischium to the dactylus inclusive are banded transversely 

 with bright red on a yellowish ground.

The anterior or gastric section of the carapace is smooth in the central 

 and hinder parts, rugose near the front, and tuberculose in the antero- 

 lateral region, where a few of the tubercles assume a spiny form ; from 

 the tubercular surface spring long slender seta3. The anterior margin of 

 the carapace is produced in the median line so .as to form an acute triangu- 

 lar rostrum which projects beyond the subacute lateral processes ; between
