436f?. BUTEO BOREALIS SOCORROENSIS. 



lu the "Proceedings" of the Boston Society of Natural History, 1871, p. 42, Mr. Lawrence 

 refers to a "Buteo horealis, var. montanus, Nutt." as being very abundant on the island of 

 Socorro, -where it is the only species of hawk to be found, and where it is a " constant resi- 

 dent, rearing its young, and subsisting entirely on land crabs ", etc. In the same paper, p. 

 10, Mr. Lawrence applies the same name to a h.iwk occurring abundantly on the Tres Marias 

 Islands, .ind there subsisting "entirely upon the Iguana lizard and rabbits." In "History 

 of North American Birds ', vol. iii, p. 283 (1874), I referred the Tres Marias bird to Buteo 

 tojcah'* var oo««aj'iccwsis, and described our only specimen from that locality as the young 

 of that form, although I h.id not, from want of specimens, been able to compare it with the 

 corresponding ago of the Central American bird. I now have strong doubts as to its being 

 the same as B. costaricensis, while as to the hawk found on Socorro I regard it quite certair 

 that it is, like the Caracara of Guadalupe (Polyborus lutosus), a species or race peculiar tp 

 that remote island, the birds of which arc for the most part entirely local. I therefore pro- 

 pose to n.ime, provisionally, the Socorro Hawk B. horealis socorroeiuis. 



440. Buteo ahbrcviatiis, Cabauis, in Schomb. Guiana, iii. 184S, 739.— "jB. zonocercus, Scl.", 

 Cooper, Orn. Cal. i. 1870, 479. (Coast of California, near San Diego.) 



* There is a male of this species in my collection said to have been obtained in Florida. It was found 

 with a collection of Florida birds, forming part of a dealer's stock, and was evidently the same "make" 

 of skin as the rest of the lot.
