In this paper Major Godwin- Austen gives tke result of an 

 examination of the type of Pellorneum tickelli, Blyth. He 

 refers it to the genus Alcippe, and shows that the species is 

 quite distinct from P. subochraceum, Swinh., to which it had 

 been united. But on this question see Lord Tweeddale^s paper, 

 Ibis, 1877, p. 451, and Major Godwin-Austen^s remarks, 

 postea, p. 115. 



The note on Pomatorhmus refers to P. hypoleucus,B\jth,var. 

 {=P. tickelli, Hume), and to the bird described by Mr. Hume 

 as P. inglesi, which seems doubtfully distinct from the true P. 

 hypoleucus, of which the types are in the Calcutta Museum. 



The Chleuasicus noticed by Major Godwin- Austen, having 

 a black eyebrow, not present in Blyth^s type of C. riijiceps, 

 is considered a variety of that species, and is described under 

 the name of C. ruficeps, var. atrosuperciliaris. The specimen 

 is from Saddya, Assam. 



7. Harvie Brown on the Distribution of Birds in North 

 Russia. 



[Ann. & Mag. Nat. Hist. ser. 4, vol. xix. p. 277, et vol. xx. pp. 1, 180, 

 494.] 



These papers give an analysis of the distribution of Russian 

 birds found north of 58° N. lat., the district being divided into 

 two — a northern and a southern division. The data concerning 

 the birds of the northern division are mainly derived from 

 the author's and Mr. Seebohm's paper published in the volume 

 of this Journal for 1876. For the data relating to the birds 

 of the southern division a list of authorities is quoted. 



Lists of the two sets of birds are given with columns 

 attached filled in with symbols denoting the rarity or reverse 

 of the birds observed, and other matters relating to their 

 distribution and migration ; and one of the chief objects of 

 the paper is to endeavour to establish a kind of geographical 

 nomenclature, which shall serve to reduce observations to a 

 common notation, and thus render more easy and more 

 certain generalizations on geographical distribution. 



The attempt is a very laudable one ; and the extreme diffi- 

 culty of rendering the manipulation of the subject at once
