690 Recently imhl'ished Ornithological Works. 



It is not possible to go more fully here into the obser- 

 vations and into the results contained in this very careful 

 piece of work, which is a grand example of the logical method 

 and clearniindedness of the French intellect, and we can 

 strongly recommend all avIio are interested in the scientific 

 study of moult, as well as breeders and others who wish to 

 be able to fix the age of game-birds, to read the work in the 

 original French. 



Cory on neiv Neotropical Birds. 



[Descriptions of twenty-eight new Species and Subspecies of Neo- 

 tropical Birds by Charles B. Cory. Publ. Field Museum of Nat. Hist., 

 Oniith. ser. vol. i. 1913, pp. i>83-292.] 



The greater number of the new forms here described 

 were collected by Mr. N. Dearborn in 1908, and by Mr. W. 

 II. Osgood in 1911, in Venezuela and Colombia. One new 

 species — Urochroma costariensis — was obtained in 1910 near 

 Limon in Costa Rica, by H. F. Raven ; while in 1912 

 Mr. Osgood was collecting in Peru, whence came another 

 new species — Laticauda riihriyinosa — from an altitude of 

 10,000 feet. 



We presume that Mr. Cory will give some further account 

 of these collections at a later date. 



Deivar'^s Sketches of British Birds. 



[Wild Birds through the Year. By George A. B. Dewar. Pp. xn-\- 

 248, 8 photo-plates. London (Herbert Jenkins). 1913. 8vo.] 



This is a series of short chatty popular sketches on British 

 Birds, many of them reprinted apparently from daily and 

 weekly journals. Though containing little that is novel 

 they form pleasant reading. The observations seem to have 

 been made chiefly in Hampshire and other southern English 

 counties. The work is illustrated by eight reproductions 

 of photographs by various artists, though some of these do 

 not seem to have any very obvious connection with the 

 text.
