51. Bent on the Birds of the Aleutian Islands, 



[Notes on Birds observed during a visit to the Aleutian Islands and 

 Bering Sea in 1911. By A. C Bent. Smiths. Misc. Coll., Washington, 

 vol. xxxvi. No. 32. 1912.] 



Mr. Bent gives us an account of the birds collected on 

 a voyage up the chain of the Aleutian Islands in the summer 

 of 1911, during which Atka, Kiska, Attu, Tanagra and 

 Alak and the western end of Unalaska were visited. The 

 specimens of birds obtained are referred to about sixty species, 

 and there is a new '^ subspecies " of Ptarmigan from Tanagra 

 Island. Examples of two other species new to the North 

 American Fauna were collected {Calliope camskatchensis 

 and Emberiza rustica). The Rustic Bunting, as is well 

 known, is an occasional straggler to the British Islands. 



The subspecies of Ptarmigan, Lagopus rupestris sanfordi, 

 has been described by j\Ir. Bent in another paper (Smiths, 

 Misc. Coll. vol. xxxvi. No, 30). 



52. Berlepsch'' s Revision of the Tanngers. 



'"Revision der Tanagriden. Von Hans, Graf von Berlepsch. Sonderabr. 

 aus Ber, d. V. Intern. Orn.-Congr. Berlin, 1910, pp. 1161.] 



This is a reprint of one of tiie papers read (or taken as 

 read) at the International Ornithological Congress at Berlin 

 in 1910. 



In Sclater's ' Tanagrinarum Catalogus Specificus/ pub- 

 lished in 1854,238 species of this Family were included, and 

 referred to 41 genera. In the eleventh volume of the 

 ' Catalogue of Birds in the British Museum ' (188G) 380 

 Tanagers were admitted, and placed in 50 genera. In the 

 present work Graf v. Berlepsch recognises 555 species, 

 and arranges them in 69 genera. These numbers shew the 

 gradual and satisfactory increase of the number of species of 

 Tanagridae met with as the progress of discovery has advanced.
