This is the earUest notice I have seen of the now well-known fact that immense collections 

 of the hones, feathers, and excrement of Swifts are occasionally found in hollow trees to 

 which the hirds have been wont to resort by thonsands for a series of years. A late anony- 

 mous writer (very weU known to me, however,) in the N. T. Independent of Oct. 7, 1875, has 

 a paragraph on the subject, in which he seems inclined to beUeve that our Chimney Swift 

 may not impossibly hybemate in such retreats. See also 1853, Thompson, Z.

This notable article opens with an account of the structure of the sternum and digits in 

 various species of the family, illustrated with ten figures. The family is divided into two 

 subfamihes, Gypselinm and Chceturince, the former having the tarsi feathered, and the ratio 

 of the phalanges abnormal ; the latter with the opposite of. these characters. The species of 

 Cypselince are all referred to the two genera Cyp&elus and Pamjptila, the latter exclusively 

 American. The Chceturince are divided into four genera, Chcetura, Oypseloides, CoUocalia
