 Part III. On the Longitudinal Distribution of the Birds of 

 the Southern Division [betiveen 64^° N. and 58°-60° N.) , 

 and a Comparison of the Faunas of the Two Divisions 5 

 with Summaries. By J. A. Harvie Brown, F.Z.S., 

 Member of the British Ornithologists' Union. 



In the last part of this paper ('Annals/ July 1877, p. 1) I 

 have treated of the distribution of species recorded by authors 

 in the Northern Division. I now propose to work out, 

 as far as my materials permit, and upon the same plan, the 

 distribution of the species recorded in the Southern Divi- 

 sion. 



The Southern Division, as I have before indicated {I. c. 

 p. 2), is that portion of North Russia south of 64^^° N. lat. 

 extending to 60° N. lat. in the S.W., to the southern boun- 

 dary of the Vologda Government, or about 59° N. lat., 

 in the S.C., and including part of the Perm Government, 

 south to 58° N. lat. and east to its eastern boundary in Asia, 

 in the S.E. I have found this southern boundary the most 

 convenient in consulting the various records of authors. It 

 would doubtless have made it more regular in appearance to 

 have included the Government of Novgorod and the northern 

 half of that of Viatka ; but at present the materials to which 

 I have access do not admit of ray doing so. Moreover, if we 

 consult the map lately issued in Mr. Mackenzie Wallace's work 

 on Russia, vol. ii.*, which shows the '^ Zones of Vegetation," 

 it will, I think, be acknowledged that Novgorod will more 

 naturally come to be entered in comparing a more southerly 

 belt of land. Should it, however, be considered by any as 

 belonging naturally to my Southern Division, the records 

 can at any time be added when the materials are forth- 

 coming. 



When Dr. A. Brandt has completed a list of the books and 

 papers treating of the fauna of Russia, upon which, he in- 

 forms me, he is engaged, the materials, I have no doubt, 

 will become more accessible than they are at present, and 

 the minutiae of distribution will be more easily worked out. 



I propose to subdivide this Division in a similar way to 

 that adopted for the Northern Division, viz. into Three 

 Districts^ which I proceed to name and define as follows : —
