Bangs on New Birds.' — In several recent papers in the Proceedings 

 of the New England Zoological Club Mr. Bangs presents some important 

 contributions to the ornithology of North and Middle America. He finds 

 that the Paroquets which formerly ranged over the interior of the United 

 States from Texas and Illinois to Colorado and the Great Lakes, differ 

 materially from the South Atlantic and Gulf Coast birds in having 

 the yellow paler and the green of a decided bluish tint. This form he 

 names Conuropsis carolinensis interior (p. 94), type locality Bald Island, 

 Nebraska. 



A new race of Calocilta, C. formosa poinpata is described (p. 102) in the 

 same publication from Bolson, Costa Rica, and a third race of Scaled 

 Quail is separated (p. 100) as Callipepla squamata pallida Brewster from 

 Arizona, etc., true C. squamata being restricted to southern Mexico. — W. S. 



Oberholser's Monograph of the Nighthawks.- — While some orinthol- 

 ogists wiU not agree with Mr. Oberholser's views as to the amount of sub- 

 specific subdivision that is desii'able there cannot, we think, be any differ- 

 ence of opinion as to the excellence and thoroughness of treatment that 

 mark this, the latest of his systematic monographs. The thoroughness of 

 the descriptions and technical discussion and the fullness of the synonymy 

 and lists of specitnens and localities leave nothing to be desired. 



Mr. Oberholser comes to the conclusion that the Nighthawks including 

 the genera Chordeiles, Nannochordeiles, Nyctiprogne, Laurocalis and Po- 

 dager represent a family distinct from the Caprimulgidse which he here 

 names Chordeilidse. Incidentally he finds differences between the Whip- 

 poor-will and Chuck-wills-widow which seem to him to warrant their generic 

 separation and Setochalcis (p. 11) with Caprimulgus vociferus Wils. as 

 its type, is proposed for the Whip-poor-wills. Of the genus Chordeiles, 

 three species are recognized, C. rupestris comprising three subspecies, C. 

 acutipennis, with five subspecies and C. virginiensis with nine. The new 

 forms are as follows, C. v. howelli (p. 57), Lipscomb, Texas, C. a. micromeris 

 (p. 100), Xbac, Yucatan, C. a. inferior (p. 109), Triunfo, Lower California, 

 C. r. xyostidus (p. 116), Bogota, Colombia, and C. r. zaleucus (p. 118), 

 Pebas, Peru. Six plates illustrate the palatal structure of Chordeiles, 

 Capriimdgus, Antrostomus and Setochalcis and the geographic range of the 

 various races of Nighthawks. — W. S.
