AETHEOPOD FAUNA OF THE WEST INDIES. 471 



hirsute ; the segments slightly narrowed at the base, the apical a 

 little longer than the penultimate. 



The prehasal plate just visible; the iasal plate about twice as 

 wide as long, a little narrower than the head in front, and 

 narrower than the first tergite behind. 



Coccal plate of the maxillipedes considerably overlapped pos- 

 teriorly on each side by the pleurae, about as wide as long, 

 sparsely punctured, the anterior border emarginate, considerably 

 overlapping the head-plate at the sides ; the jaws moderately 

 long, the claw a little overlapping the head-plate in front, but 

 the joint of it falling considerably short of the basal joint of 

 the antenna. 



Tergites smooth, somewhat strongly bisulcate. 



Sternites smooth, but mesially impressed. 



Anal somite : tergite wide, almost completely covering the 

 pleurae ; pleurae smooth and not porous ; sternite wide, wider 

 than long. Legs slender, hairy, not much louger than the pre- 

 ceding pair, without a claw, or at most with a very minute one ; 

 in S distinctly thicker. 



Number of pairs of legs, $ 49, S 45. 



Length up to about 31 mm. 



Locality. Mustique Island {TL. H. Smith). 



" Under rubbish in damp places." 



This species may be readily recognized from G. tenuitarsis by 

 the much smaller number of its legs, G. tenuitarsis having as 

 many as eighty-five pairs.
