Schaub on the Nest-doivn of Birds. 



[Die Nestdimen cler Vcigel unci ihre Bedeutung fiir die Phylogenie der 

 Feder. Von S. Scliaub. Verliandl. naturf. Ges. Basel, xxiii. 1012.] 



In this paper the author combats the views of Mr. Pycraft 

 and endeavours to uphold those of Gadow. He believes that 

 the first or neoptile plumage is always developed from the 

 same papilla, and in direct continuity with the second down 

 or deuteroptile and the definitive feather or teleoptile, and 

 it is not possible to consider the three successive feather- 

 coverings as separate generatiuus, and further that the 

 neoptile is not primitive, but a secondary development, and 

 cannot be used to trace the connection between repiiliau 

 scales and definite feathers. 



Sclater on the Ornithological Literature of 1911. 



[Zoological Record, vol. xviii. Aves. By W. L. Sclater, M. A. London, 

 October 1912. Pp.115.] 



The Report on ^Aves' from the volume of the Zoo- 

 logical liecord for the year 1911 is by the same author 

 as the preceding Record (for 1910), and follows nearly 

 the same plan. The list of titles of zoological works and 

 papers with which it commences, contains 1536 entries, 

 the corresponding number for 1910 being 1721. The 

 systematic arrangement followed is, as in the last report, 

 that of the late Dr. Rowdier Sharpe.
