COTYLE.

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

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

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

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

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



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

 one really belonging to the genus is the cosmopolitan G. riparia. 

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

 feathers a1 the base of the hind toe, and the unusual length of 

 the lateral claws, combined with the lateral nostrils overhung by 

 membrane.

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

 Rica ? 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 with 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.
