CANCROIDS A. 221 



ticulate. Posterior feet sparsely pubescent, third joint above mi- 

 nutely spinulous, tarsus long. 



Plate 12, fig. 9, animal, enlarged four diameters. 



From Balabac Passage ; also a similar species from Raraka Island, 

 Paumotu Archipelago. 



The specimen from Balabac Passage is quite small, the length of 

 the carapax being 1-7 lines, and the greatest breadth, 2'6 lines; ratio of 

 length to breadth, 1 : 1-53. The Raraka specimen (a female), is two 

 and two-thirds lines long, and four broad; ratio, 1 : 1-5. The carapax 

 anteriorly is minutely rough under the microscope, especially near the 

 antero-lateral teeth ; and in this part the areolets are somewhat pro- 

 minent and pointed or scabrous. In the Raraka specimen, one or two 

 of the antero-lateral teeth have a spine on the outer side, and the 

 obsolescent tooth E is a minute spinule. The minute points or tuber- 

 cles of the hand extend half way down its inner surface. The fingers 

 are black or nearly so. 



This species resembles the P. pugil, but the front is much less pro- 

 jecting, the outline being more nearly straight, and the tubercles of 

 the hand are far smaller and more numerous; moreover, the areola- 

 tion is not as bold.

Carapax faint areolate anteriorly and short hirsute, antero-lateral 

 margin short, with four to five clusters of nearly equal spinules, 

 which are hardly seen without removing the hirsute covering.
