The 1st pair of legs are about If times, the 2nd and 3rd pairs are 

 about 2J times, the length of the carapace, while the 4th pair are about 

 as long as the carapace. 



In the male (female unknown) the first 5 abdominal terga are 

 transversely cariuated, but the 4th and 5th carinas are faint. The 

 sternum is also cariuated on either side of the abdomen, as in P. Jukesii, 

 but the crests are much lower. 



In the Indian Museum is a single male specimen from the Anda- 

 mans : its carapace is 9 millim. long and 11 broad.

Carapace with the regions well defined and cut up into a multitude 

 of symmetrical convex areolae, its whole surface is covered with crystal- 

 line granules which are enlarged on the convexities of some of the 

 areolae. 



Front cut into 4 teeth, the middle two of which, though deflexed 

 and on a lower plane, are much sharper and more prominent than the 

 others : lateral borders of the carapace posteriorly divergent, cut into 

 five ragged teeth, inclusive of the orbital angle : posterior border cut 

 into from eight to ten well spaced even tooth-like lobes. 



Upper border of orbit with 3 deep notches, lower border with a 

 notch and a fissure : eyestalks sharply granular. Ischium of the 

 external maxillipeds longitudinally grooved. 



The chelipeds of the female (male unknown) though shorter than 

 the carapace are stouter than the first pair of legs : they may be sub- 

 equal or unequal : the arm, wrist, and the upper surface of the palm 

 are sharply granular, the palm is rather fall and is not elongate, being 

 about half again as long as high and less than half again as long as the 

 fingers. 



The 1st pair of legs are about as long as the carapace : their merus 

 is sharply granular and its anterior border ends in a spine : their 

 propodite and dactylns are thin and compressed but not broadened, and 

 their posterior border is evenly serrated. 



The 2nd and 3rd pair of legs are a little over If times the length of 

 the carapace : their merus is very stout and broad, with a granular 

 dorsal surface and sharply though irregularly serrated edges : their 

 carpus has the anterior border cristiform and irregularly serrate, and 

 the posterior border subcristiform up to a terminal spine : their pro- 

 podite and dactylus are short and broadly foliaceous, with the posterior
