Diagnosis. — ^Analogous to P. depressiuscula. Body thicker, and 

 narrower, two-sevenths broader than long, depressions deeper- 

 anterior part of branchial elevation high, prominent, forming a semi, 

 detached nodule. Tubercles of carapace and chelipeds coarser than 

 in depressiuscula and marginal teeth stouter and shorter, more 

 lobiform than spiniform. While the arrangement of tubercles is 

 almost identical, there is a row of tubercles and granules in front of 

 the posterior margin, which is almost wholly absent from depressius- 

 cula. The posterior margin is a little more arcuate, and the large 

 tubercle at either end is very much larger than the intermediate 

 tubercles. Front wider, more inclined and distinctly trilobed. Basal 

 half of fingers with more numerous fine granules. 



Measurements. — Female (Ilha Victoria), length of carapace 31.3, 

 width of same 40.4, length of hand 30.3 mm.
