Since all of the West Indian decapods that are known to occur 

 above the high-tide line are treated here, a number of strictly marine 

 forms are unavoidably included. In the rock-strewn littoral zone of 

 the sea, particularly in the vicinity of cliffs, Grapsus grapsus is fre- 

 quently seen perched on the tops or sides of boulders protruding 

 above the water line. In company with this species in such habitats 

 and on sea walls, Plagusia depressa frequently emerges from the water 

 but remains relatively close to the tide line. 



Along cobble or rocky beaches (pi. 3a and b), Geograpsus lividus 

 and Cyclograpsus integer are common, and in some areas Petrolisthes 

 guadratus occurs among the rocks that are partially embedded in the
