3- EuPAGURUs iNvESTiGATORis, n. sp. Plate XI., fig. 2. 

 Closely related to E. zebra, Henderson. 



Rostrum broadly triangular, but acute, reaching between ophthalmic 

 scales and far beyond the antennal angles of the carapace. 



Eyestalks slender, slightly longer than anterior border of carapace, 

 reaching to distal third of terminal joint of antennular peduncle and slightly 

 beyond the antennal peduncle : eyes little expanded : ophthalmic scales 

 distant, acute or minutely spinulose at tip. 



Antennal acicle curved, setose, reaching beyond middle of terminal 

 joint of antennal peduncle : flageilum 2^ times the length of the carapace, 

 sparsely setose. 



Chelipeds setose, sufficiently so on the hands as to obscure though not 

 conceal the sculpture. 



The right cheliped, which is much the more massive, is about 2\ times 

 the length of the carapace : the merus is smooth, and its cristiform inner 

 lower border is strongly hirsute and its outer lower border distally spinose ; 

 the carpus is longer than the combined ischium and merus, and longer than 

 the palm ; its upper border is spinose, its outer surface is longitudinally 

 traversed by a spinulose carina, below which are numerous sharp granules : 

 the palm is very little broader at its distal end than at base, its length is 

 about 1^ times its breadth ; the upper and lower borders are well defined 

 and serrated; when denuded, its outer surface (as also of fingers) is thickly 

 studded with coarsish spinules which have a tendency to fall into lines ; 

 there is no oblique crest on the inner surface of the palm: the dactylus 

 IS considerably shorter than the palm, and is longer than the fixed finger, 

 but narrower. 



The left cheliped reaches to the base of the right dactylus : the lower 

 border of the merus is spinose : the carpus is about as long as the combined 

 hand and fingers ; its upper surface carries two raised longitudinal rows of 

 spines which are continued on to the palm : the fingers are longer than the palm. 



The 2nd and 3rd legs do not quite reach the tip of the larger cheliped, 

 and are smooth and very sparsely setose : the dactyli are about as long as 

 the two preceding joints combined. 



Colours in spirit : pinkish yellow, with broad longitudinal red stripes 

 on the merus-joints only of the chelipeds and legs, and a small red patch at 

 the proximal end of the upper surface of the carpal joints. 



Length of carapace about 12 millim.
