This iw tho earliest notice I have seen of the now well-known fact that immense collectioas 

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

 whicli tho birds have been wont to resort by thousands for a sci'ies of years. A late anony- 

 mens writer (very well known to me, liowever,) in the N. T. Independent of Oct. 7, 1875, has 

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

 may not impossibly hybernato in such retreats. See also 1853, TiiOMi'sON, Z.

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

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

 subfamilies, Cypselinoe and Chceturince, the former having the tarsi feathered, and the ratio 

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

 Cyp««K««B are all referred to the two genera Cypselus nud J'anyplilu. ihe latter exclusively 

 American. The Chceturince are divided into four genera, Chatura. Cypscloides, Collocalia,
