 There are also specimens in this 'Museum from Charles Island in the same 

 archipelago, collected during the voyage of the " Ilassler." 



Compared with the typical form from Florida, the Galapagos specimens 

 have a higher and absolutely perpendicular front, the frontal lobes projcct- 

 inf>- even further forward than in specimens from Acapulco labelled '' Grapsus 

 altifrons " by Dr. Stimpson. The spots upon the carapace and legs are fewer 

 and more definitely circumscribed than in Florida specimens, and the outer 

 face of the carpus and hand of the chelipeds is uniform red. The ambulatory, 

 leers are more robust. Carapace of a male, 63 X 69 mm.
