spinose disially, the propodite and dactylus are spiiiose along the upper 

 surface, and the outer surface of the dactylus is longitudinally grooved. The 

 propodite of the third left leg is half as broad as long and has its outer surface 

 spinose. 



Colours in spirit : yellowish white, with faint pink cross-patches on the 

 eyestalks, and merus, carpus, and propodite of the chelipeds and legs. 



Length of carapace 15 millim. 



Inhabits broad shells, such as Strombus and Oliva.

Of two specimens taken by m5'self, at the same moment, in the lagoon 

 of a small islet of the Andaman group, one corresponds with P. euopsis, the 

 other with P. depressus. 



Pas:urus euopsis differs from P. punctulatus, which it resembles in the 

 hairiness and spinosity of its chelipeds and legs, in the following particulars : — 



(i) The carapace is more depressed, especially in the variety depressus. 



(2) The eyestalks are much longer than the anterior border of the 

 carapace, and are longer than the antennular peduncles, and are decidedly 

 broadened distally. 



(3) The antennal acicle is extremely short, not reaching to the base 

 of the last jomt of the peduncle. The joints of the distal half of the antennal 

 fiagelium have the antero-internal angle produced. 



(4) The chelipeds and legs are thickly beset with stiff, long, brownish 

 or red-and-white bristles as in P. punchilatus, but the thorn-like spines are 

 much less numerous, on the legs especially.
