Geograpsus eydouxi (Milne Edwards). Chili. (This species is regarded by 
Kingsley as identical with Pachygrcipsus crassipes, Randall, but I believe 
its true place to be in the genus Geograpsus, since Milne Edwards says of 
the chelipedes “ pinces aigiies.”) 
Geograpsus (?) longipes (A. Milne Edwards). New Caledonia. 
Geograpsus hillii (Kingsley). West Indies ; Florida. 
Geograpsus grayi 1 (Milne Edwards).

Carapace subcpiadrate, depressed or nearly flat on the dorsal surface, with the antero- 
lateral margins arcuated and dentated ; the branchial regions not defined as in Vavuna ; 
in the middle of the carapace is an H -shaped impression formed by part of the cervical 
and cardiaco-branchial sutures ; the epigrastic lobes are well-defined ; the front is but 
slightly deflexed, and its anterior margin is sinuated or nearly straight. Orbits small, 
with the interior subocular lobe acute or subacute. Epistoma very short and widely 
transverse. Buccal cavity large ; the ridges of the endostome or palate not very distinct. 
Post-abdomen of the male distinctly seven-jointecl ; the basal segments do not cover the 
whole width of the sternum, between the coxae of the fifth ambulatory legs. Eye- 
peduncles short. Antennules transversely plicated. Antennae with the basal joint short 
and not markedly dilated at the antero-external angle, it sometimes does not reach the 
infero-lateral frontal process. Exterior maxillipedes with the exognath much dilated, 
as broad or nearly as broad as the ischium of the endognatli ; the merus of the endognath 
1 It is possible, as Mr. Kingsley has pointed out, that the species described by Dana as Grapsus crinipes is identical 
with Geograpsus grayi, and if so, his name having priority, must be used for the species, but I prefer to refer to it for the 
present under the designation which has been more generally adopted for it, since Dana’s description is somewhat insuffi- 
cient, and may belong to a species of Pachygrapsus.
