Generic 



characters. 



The cleft-toed Sandpipers are very easily diagnosed. The characters of toes deft to the 

 base and difference in length between the shortest and longest primary much more than the 

 length of the bill, exclude every other genus in the family except Strepsilas and Phegornis. 

 From the former they may be diagnosed by the character nasal aperture situated within 

 the basal fourth of the bill, and from the latter by the fact that the first primary is much 

 longer than the fourth.
