Recently published Ornithological Works. Ill 



species are mentioned^ such as Phasianus satscheunensis, Ph. 

 tarimensis, Ph. strauchi, Ph. vlangalli, Sitta eckloni, Pyrgi- 

 lauda kansuensis, and Rhopophilus deserti, which, so far as we 

 know, have not yet been described. Anser indicus was found 

 breeding in the oasis of Sat-schen, north of the Nan-schan 

 (p. 64). 



29. Radde's ' Urfiis Caucasica.' 



[Omis Caucasica. Vou Dr. G ustav Radde. Lief, i.-xvi. 4to. Kassel : 



1884.] 



The first three parts of this long-expected work are now 

 before us and carry on the general subject to the middle of 

 the Laridse. The introduction, giving an account of how the 

 author was induced to undertake the task, and of his views 

 on species are worth perusal. Dr; Radde is a decided " lum- 

 per ^^ as regards species. For him Garruli glandarius, kry- 

 nickii, melanocephalus , and hyrcanvs are all one. Sturnus 

 unicolor is not specifically distinct from St. vulgaris, much 

 less ^t. pujyurascens, St. nitens, and St. poltarutskyi, and the 

 same plan is pursued in similar cases. Dr. Eadde acknow- 

 ledges 367 species and 66 varieties of Caucasian birds. We 

 observe that he calls the Caspian species of Porphyrio '' P. 

 veterumJ" But it has been pointed out by Sclater (Ibis, 

 1879, p. 195) that this name originated in error, as will be 

 seen at once by those that will take the trouble to refer to 

 S. G. Gmelin^s ' Reise; ' and, as regards the validity of the 

 species, it has been shown by Mr. Seebohm (Ibis, 1881, p. 429) 

 that the Caspian bird is the same as the Indian P. polio- 

 cephalus.
