The genus Ereunetes of Illiger has for its type a species, called E. petrificatus by him, from 

 Bahia, supposed to be identical with Tringa semipalmata, although the description, "smaller 

 than Actitis hypoleucus, the colors similar," leaves much to be desired. 



The bill of our species of Ereunetes is quite stout and considerably expanded, by which it is 

 readily distinguished from Adodromas wilsonii independently of the semipalmated feet. The 

 tarsus and middle toe are about equal ; the tibia denuded anteriorly for about two-thirds the 

 length of tarsus. The basal membrane of toes is more scolloped out interiorly than exteriorly ; 

 the notch externally not quite as deep as to the first joint, although the membrane extends 

 beyond the second. There is a tendency to hexagonal sub-division in the bare portion of tibia 

 anteriorly. The tail is doubly emarginate.
