It differs from G. forcipatiis Adams and White in having no 

 "dilated lobe between the eyes" and no great tooth near the end of 

 the fingers. The meros-joints of the walking-feet are less dilated 

 than in G. brevipes.

Plate XIV, Fig. 2

 1858. 



Carapax strongly convex in a longitudinal sense, its median dorsal 

 outline forming almost a semicircle. It is very broad anteriorly 

 (broadest at the prominent angles of the orbits) and considerably 

 narrowed behind. Length to breadth as i : 1.6. Branchial regions 

 not inflated. The lines bordering the anterior and antero-lateral 

 margins are sharply raised. Front very broad, somewhat truncated 

 below. The supraorbital margin is but slightly undulated, most so 

 near its exterior extremity ; both crests are minutely crenulated, and 

 the lower or anterior crest is less convex than usual. The peduncles of 

 the eyes are not very long, the eye falling a little short of the exterior 

 extremity of the orbit. The exterior angle of the crenulated inferior 

 margin of the orbit is broadly rounded, as in G. palustris. The large 

 cheliped of the male is well developed ; meros with obtuse, granu- 

 lated angles, and no very prominent tooth at the summit ; hand 

 minutely granulated, with palm about two-thirds as long as the fin- 

 gers, not strongly armed within, the inferior oblique crest prominent 

 with a single row of granules, the crest at base of fingers nearly ob- 

 solete, the superior crest not bifurcated and scarcely tuberculated ; 

 fingers slender, smooth, strongly gaping, their inner margins evenly 

 curved and minutely toothed, with two or three conical teeth a little 

 larger than the rest ; extremity of immovable finger longitudinally 

 emarginated. Ambulatory feet naked ; meros of moderate width ; 

 dactylus short, not compressed. 



Colors : The carapax is of a light opaque-blue color, transversely
