 436cZ. Buteo borealis socorroensis. 



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

 refers to a "Huieo 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. 2So (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 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 certain 

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

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

 ■posc to name, provisionally, the Socorro Hawk Ii. borealis socorroensis.

* 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 skui as the rest of the lot.
