Chapman on the Birds of Eastern North America. 



[Handbook of Birds of Eastern North America, with Introductory 

 Chapters ou the Study of Birds in Nature. By Frank M. Chapman. 

 Pp. xxx + 'jSO, 24 pis., 13G text-figs, ffevised edition. New Yorlt and 

 London (D. Ajipleton & Cumpauy) : 1912. &'m. Svo. P;-ice S3. 50.] 



This new edition of Mr. Frank Chapman^s well-known 

 handbook lias been thoroughly revised, and contains several 

 new and valuable features. The introductory portion has 

 been increased to one hundred and sixteen pages, and contains 

 chapters on migration, song, nesting-habits, colour, structure, 

 and food, which may be read with considerable profit. The 

 space given to the description of each bird has not been mate- 

 rially increased, but has l)een revised, especially as regards 

 nomenclature and distribution. In these matters the last 

 (1910) edition of the B. O. U. Check^list has been closely 

 followed. Other new features are a zone-map of North 

 America, adapted from that of the Biological Survey, and 

 a useful colour-chart. 



We can thoroughly recommend this little work, the first 

 edition of which was published so long ago as 1892, as the 

 most useful guide to the study and identification of North 

 American birds.

Mr. Chapman describes an interesting new Ibis resembling 

 in a general way Hugedashia hagedash, but which differs iu 

 having a very distinct nape- crest of rounded feathers and 

 the orbital and loreal space bare of feathers. For this he 

 proposes the name Oreuihis akleyorum, gen. et sp. nov. 



The bird Avas discovered and obtained by the Avell-knowu 

 American taxidermist Mr. C. E. Akeley, who, with his wife, 

 has been recently collecting in various parts of British East 

 Africa. The examples obtained were met with on the southern 

 slopes of Mt. Kenia, at an altitude of about 9000 feet, 

 while other specimens were observed at similar altitudes on 

 Mt. Elgou and iu the Aberdare mountains. The species
