unaccompanied by the eggs themselves. In order to make the 

 paper of more general interest, I have added to each species 

 mentioned, an account of its geographical distribution, as supplied 

 by Baird in his excellent quarto Catalogue of North American 

 Birds,* and hav^e given in some cases references to Brewer's work 

 on North American Oology. + 



l.J Cathartes aura (Lin.) — Turkey-Buzzard. 



A nest of 2 eggs sent, concerning which Mr Jones writes : — 

 ^' Collected in Harford county, Maryland, 8/5/70. It builds on 

 the ground, and in caverns of rocks, in which latter situation these 

 eggs were taken. They never lay more than 2 eggs, as far as my 

 information goes." 



The measurements of these eggs are as follows: — Spn. 1 is 

 2-07 in. by 2 in; Spn. 2 is 2*8 in. by 2 in. The shape of Spn. 1 is 

 nearly elliptical, the greatest breadth being at the centre, and the 

 ends equally rounded; and in Spn. 2, the greatest breadth is 

 towards one end. (K Egg-Book Mus. Feiiden and Harvie- 

 Brown, p. 186). 



The Geog. Bangs of this species is very extensive, including the 

 " whole of N. America, except the Arctic regions " (Baird).

14. Astur africapillus (Wils.) — American Goshawk. 



1 egg. " Collected at Lapwai Creek, Idaho territory, 

 25/5/71, by Capt. Chas. Bendire, 1st U.S. Cavalr}^ Nest in a 

 Cottonwood tree. I obtained 2 eggs, and send you 1. They are 

 the only eggs of this species I have ever obtained." Capt. Bendire 

 is a well-known collector, who was stationed in Arizona, and made 

 a large collection of rare eggs there. {V. Egg Bk. Mus. F. and 

 H.-B., p. 270).

 portions " (Baird). It has also occurred in Great Britain, and a
