Length of carapax, seventeen and one-third lines; breadth, nineteen lines; length of front, six and three-fourths lines; breadth of front to front of præmedial areolets (which but slightly project), two and one-fourth lines. Colour, finely lined and spotted irregularly with brown-ish black or black, with intervening spaces a little yellowish.
Sides of carapax much arcuate. The species is near G. variegates; but according to Edwards’s description of that species, and the figure in Guerin’s “Iconographie.” It has the third joint of the outer maxillipeds much oblong, while in this species, the joint is not longer than broad.
The figure in the Voy. De l’Uranie, under Freycinet, pl. 76, f. 2, may be this species.”
