ORNITHOLOGY. — Annotated catalogue of a collection of birds made 

 by Mr. Copley Amory, Jr., in northeastern Siberia. J. H. Riley. 

 Proc. U. S. Nat. Mus. 54: 607-626. 1918. 

 Mr. Copley Amory, Jr., who accompanied the Koren Expedition 

 to the Kolyma River of northeastern Sibera in 19 14, made a collection 

 of 228 birds. These were obtained at localities ranging from near the 

 mouth of the Kolyma River to the Tomus Chaja Mountains, and are 

 referable to 76 species and subspecies. This paper is an annotated cata- 

 logue of these, and includes the localities and dates where each species 

 was observed or collected, together with remarks on plumage and the 

 status of races, and Mr. Amory's field notes on habits and distribution. 

 Some of the interesting results of the study of this collection are the sub- 

 stantiation of Mr. G. M. Mathews' division of Canutus canutus into 

 three subspecies ; of the recently described Budytes flavus plexus Thayer 

 & Bangs; and of Otocoris alpestris euroa Thayer & Bangs. It is also 

 worthy of note that the Lapland longspur occurring in the Kolyma dis- 

 trict is much nearer Calcarius lapponicus alascensis than to Calcarius 

 lapponicus coloratus. Harry C. OberholsER. 



ORNITHOLOGY. — Description of a new subspecies of Cyanolaemus 

 clemenciae. Harry C. Oberholser. Condor 20: 181-182. Sep- 

 tember, 1918. 



Examination of a series of Cyanolaemus clemenciae discloses the 

 existence of a hitherto unrecognized subspecies, which will stand as 

 Cyanolaemus clemenciae bessophilus. It differs from Cyanolaemus 

 clemenciae clemenciae in its shorter bill, duller upper parts, and paler 

 lower surface. It ranges from southeastern Arizona, southwestern 

 New Mexico, central western Texas, south to the State of Chihuahua, 

 Mexico, and in winter to Vera Cruz. H. C. O. 



ORNITHOLOGY. — Description of a new Lanius from Lower Cali-

 fornia, including the adjacent islands, proves to be subspecifically dis-
