tailed Hawk {Buteo borealis umbrinus) from Florida,^ based on a single 

 specimen collected at Myakka, Manatee County. He thinks it may be only 

 a straggler to Florida from Cuba. Mr. Bangs has also described a new 

 subspecies of Stclgidopteryx {S. ruficollis cequalis) from Santa Marta, 

 Colombia,"^ and passed in review the other members of the ruficollis group, 

 namelv, 5. tiropygialis Lawr., and 5. fnlvipennis (Scl.), which he looks 

 upon as merely subspecies of >S. ruficollis. 



In conjunction with Mr. Brewster, he has also distinguished a new form 

 of Ailhurus from Jamaica,^ which these authors have named Aithurus 

 scitulus, distinguished from A. polytmns by smaller size, darker colors, and 

 a much shorter, wholly blnck bill. — J. A. A- 



Bangs on Birds from the Liu Kiu Islands.^ — A collection of 107 speci- 

 mens recently received by the Museum of Comparative Zoology, was found 

 to comprise 56 forms, of which six are described by Mr. Bangs as new. 

 The paper forms an important addition to our knowledge of the ornithol- 

 ogy of these little known islands. — J. A. A. 



Chapman on New Birds from Peru." — A small collection of birds made 

 by Mr. H. H. Keays, for the American Museum of Natural History, at 

 Inca Mines, southeastern Peru, proved of exceptional interest, containing, 

 besides several rare species, six forms that Mr. Chapman has charactei"- 

 ized as new. These are C/doroc/irysa ftilgeHtissima, M«lacothraupis cas- 

 taiieiceps, Euphonia xanthogastra bruiineifrons, Chlorospingusjiavigularis 

 purvirostris, Ochthccca keaysi^ and Terenura xanthonota. — J. A. A. 



Grinnell on New California Birds. — In recent numbers of 'The Con- 

 dor' Mr. Joseph Grinnell continues to distinguish local forms among the 

 birds of California, characterizing in the May-June issue (pp. 65, 66), two 

 new forms of the Yellow-throat, under the names of Geothlypis trichas 

 scirpicola and G. t. sinuosa, the former being a "permanent resident " of the 

 fresh-water tule beds of Los Angeles County and the latter a "permanent 

 resident " of the salt marshes about San Francisco Bay. G. t. sinuosa is 

 thus a further refinement of G. t. arizela Oberh., which Mr. Grinnell 

 allows a wide range on the Pacific slope in the breeding season, — from 

 "Central California to British Columbia."
