I now believe the Jongitarsis form to be an independent species. Beside 
the characters given in the work above cited, @. longitarsis has the anterior 
half of the carapace more tuberculous, front wider, and the ridge running 
lengthwise across the middle of the palm less distinct than in G. s : 
Although the fingers are narrower at the tip than in typical Grapsus, thea 
are much more hollowed underneath than in Geograpsus.

The width of the meropodites of the ambulatories in this and the fol 
lowing species is not a dependable character. In the U.S. National Museum 
there are specimens of G. grayi from Glorioso Id. in which the meropodite 
are less than half as wide as long, and a series from Japan in which they are 
more than half as wide as long. 
In G. ecrinipes, which have been handled (from 7 localities), the me opo- 
dites are commonly less than half as wide as long, sometimes just half as 
wide as long. }
