436a\ Buteo borealis socorroensis. 



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

 refers to a "Buteo borealis, 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 hawk occurring abundantly on the Tres Marias 

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

 of North American Birds", vol. iii, p. 285 (1874), I referred the Tres Marias bird to Buteo 

 borealis var costaricensis, and described our only specimen from that locality as the young 

 •of that form, although I had not, from want of specimens, been able to compare it with the 

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

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

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

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

 pose to name, provisionally, the Socorro Hawk B. borealis socorroensis.

 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.
