gone so far as to produce genera distinct from their conti- 

 nental allies. As has been frequently asserted, the effect of 

 a residence in an oceanic island upon birds is to increase the 

 size of their bills and feet, to shorten the wings and tail, and 

 to darken the colours ; this rule appliess strictly to the birds 

 of Guadalupe Island. The change, as Mr, Ridgway points 

 out, has not as yet proceeded far ; but enough is seen to show 

 that the law at work in most parts of the world is in action 

 here also. 



5. Godwin- Austen on three new Species of Birds from 

 Assam. 



[Description of tliree new Species of Birds of the Genera Pellorneum, 

 Actinura, and Pomatorhinus, lately collected in the Neighbourhood of 

 Saddya, Assam, hy Mr. M. J. Ogle, of the Topographical Survey. By 

 Major H. H. Godwin-Austen. J. A. S. B. xlvi. pt. ii. p. 41 (1877).] 



The three species here described are : — 



(1) Pellorneum pectoralis (p. 41), from Saddya. — In his 

 notes on this species Major Godwin- Austen refers to the 

 vexed question of Pellorneum tickelli, Blyth ; but his views 

 here expressed are altered in his subsequent paper. 



(2) Actinura oglei (p. 42) : shot on Manbum Tila, on the 

 Tenga-Pani river, near Saddya, at an elevation of 800 feet. — 

 The species is compared with Turdinus guttatus, Tickell, a 

 bird which Major Godwin- Austen considers to be incorrectly 

 placed in the genus Turdinus. 



(3) Pomatorhinus stenorhynchus (p. 43) : Manbum Tila, on 

 the Tenga-Pani river, near Saddya (800 feet). — This species 

 has a slender bill approaching that of Xiphorhamphus , its 

 coloration recalling P. ferruginosus. 



In the same collection are other new species, the names of 

 which are given here, but the description of which is reserved 

 for a future paper.
