The spinules on the cheHpedes agree closely with de Man's description. On the 

 outer surface of the carpus there is a comparatively broad longitudinal smooth Hne 

 which separates the closely packed small spinules of the upper surface from the very 

 much larger and more sparsely distributed spinules of the lower surface. 



In the largest male there are on both chelae five teeth on the fixed finger and four 

 on the dactylus ; in the smaller individuals they are less numerous, two or three on each 

 finger. The anterior tooth on the dactylus is placed a Httle behind its middle point, 

 the foremost on the fixed finger being posterior to it. These two teeth are larger than 

 any of the others and the margin behind each of them is distinctly concave. 



The synonymy of P. nsglectus has been dealt with by de Man. In the Indian 

 Museum there are two of the specimens which he recorded from Mergui in 1888 under 

 the name P. acutirostris. These appear to be specifically identical with those described 

 above, but unfortunately all the chelipedes are missing except one, which is small. 



The specimens obtained by Dr. Annandale were found in a rapid running stream 

 in the Botanical Gardens at Penang. All of them, in life, bore a small black spot on 

 each side of the abdomen at the junction of the ist and 2nd, 2nd and 3rd, 4th and 5th 

 and 5th and 6th abdominal somites. No spot occurred at the junction of the 3rd and 

 4th somites. In the smaller individuals there was a dark slanting line near the 

 posterior margin of the carapace and another, similar to it, not far from the anterior 



Both chelipedes detached.
