The chelipeds are unequal, the larger one being not quite twice the 

 length of the carapace: the arm has 2 or 3 spines at the distal end of 

 the anterior and posterior borders ; the upper and outer surfaces of the 

 wrist and hand are covered with sharp spine-like tubercles which 

 become blunt and pearl-like in the lower part of the hand, and one or 

 two of the spines at the inner angle of the wrist are enlarged ; fingers 

 with some sharp tubercles at base. 



Legs with numerous long sharp spines (which are a good deal 

 concealed by long stiff hairs) along the upper border, — a single series 

 on the meropodites, 2 or 3 series on the carpopodites and propodites. 



Colours in spirit: yellowish or greenish brown, somewhat mottled 

 on the carapace and somewhat banded on the legs ; fingers black, the 

 colouration not extending to the hand. 



In the Indian Museum are 20 specimens, from the Andamans and 

 Mergui. 



This species is suspiciously like the Pilodius pugil of Dana. 



94. Ohio rodopsis wood-masoni, n. sp. 



Carapace with a few rather long scattered hairs, legs with similar 

 but more numerous hairs, not in any way concealing the sculpture, 

 chelipeds almost free from hairs. 



The carapace is thick, and has the regions and subregions well 

 defined, in its anterior f , by broad smooth grooves, and coarsely and 

 unevenly granular. 



The front is cut into two sharply denticulate lobes, the outer angle 

 of each of which is very distinctly isolated and spine-like. The orbital 

 margin is denticulate and has the three fissures distinct. 



The antero-lateral margin has four large procurved spines, some 

 of which (almost constantly the second one) may have an accessoiy 

 spinule near the tip. Three or four of the lobules just inside either 

 antero-lateral margin bear each a somewhat similar spine. 



The outer angle of the basal antennal joint is prolonged into the 

 orbital hiatus. 



The chelipeds are unequal, the larger one being not quite twice the 

 length of the carapace. The arm has one or two spine-like teeth at 

 the distal end of both the anterior and the posterior border ; the wrisr, 

 is studded with spine-like tubercles and has a pair of strongish spines 

 at the inner angle ; the hand has spine-like tubercles along the upper 

 surface, and close-set pearly granules along the outer and lower sur- 

 faces ; fingers with spine-like denticles at base only. 



Meropodites of legs with the upper border spinulate ; carpopodites
