COTYLE, $19 
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, the 
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 Cotyle, but the only 
one really belonging to the genus 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 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.
