COTYLE. 



319 



on inner face, and having also a small tuft of feathers attached to posterior 

 edge uear the hind toe. Middle toe with basal joint adherent externally to 

 near the end, half way internally, the claws comparatively little curved, the 

 lateral reaching beyond the base of middle. Tail slightly forked. Color dull 

 lustreless brown above, in riparia white beneatli with gray pectoral band. 



Many American birds have been referred to Cotyle, but the only 

 one really belonging to the genua is the cosmopolitan C. riparia. 

 The peculiarity of the genus consists essentially in the tuft of tarsal 

 feathers at the base of the hind toe, and the uu jal length of 

 the lateral claws, combined with the lateral nostrils overhung by 

 membrane.

Hab. The whole of North America; Bermudas; Greater Antilles; Costa 

 Bica ? Also found in northern parts of the old world. 



A careful comparison of the European specimens in the Smith- 

 sonian collection with American does not furnish any tangible 

 grounds for separation ; although the former, on the whole, appear 

 to have longer wings, and more deeply forked tail witn narrower 

 feathers. 



Specimens are in the collection from many localities throughout 

 eastern and middle provinces of United States. Only one specimen 

 from western province, and this is somewhat doubtful.
