S. I. Smith on American Crustacea. 



115 



The number of Anaericau species now known is quite large. Ed- 

 wards, in his review of the Ocypodoidea in the Annales des Sciences 

 naturelle for 1852, enumerates, including his Acmdhoplax insignis^ 

 eight species as appertaining to America. In 1855 Major LeConte 

 described another species [G. mmax), and in 1859-60 Dr. Stimpson 

 added three others. In the following pages nine more are described, 

 making in all twenty-one species known in the American faunce. Of 

 the species which I have personally examined none are common to the 

 east and the west coast. Edwards, however, mentions one species 

 ( G. stenodactylus) as occurring in Chili and Brazil, but even in this 

 instance there may have been some mistake. The following list will 

 illustrate the distribution of the species on the two coasts. The local- 

 ities from which I have examined specimens are followed by an !.
