THE GRAPSOID CRABS OF AMERICA. 319 



hills of Jamaica. The bases between the leaf bases of the pine form 

 natural rain-water reservoirs, which do not fail even in dry weather, 

 and these aquaria are tenanted by the crabs and other small creatures. 

 The flat back of the crab (looking as if it has just passed through a 

 mangle) enables it to crawl easily in the narrow spaces between the 

 leaves. (Jarvis.)

Genus METASESARMA Milne Edwards. 



Metasesarma MILNE EDWABDS, Ann. Sci. Nat., ser. 3, Zool., vol. 20, 1853 r 

 p. 188 [154] ; type, M. rousseauxi Milne Edwards. 



Antenna excluded from orbit. Front vertical. 



Differs from Sesarma, in having the tooth at the lower inner angle 

 of the orbit meet the front near its lower angle, so as to exclude the 

 antenna from the orbit. The reticulation of the under side of the 

 carapace is finer, closer, and more confused. 



Front vertically deflexed and deep. Supra-frontal tubercles feebly 

 marked. 



Distributed through the Indo-Pacific region and the east coast of 

 Middle and South America.
