25. Thanner on the Birds of Grand Canary Island. 
[Beitrage zur Ornis Gran Canaria’s. Von Rudolf v. Thanner. Orn, 
Jahrb. xxi. Heft 3 (1910).] 
A few years ago it was supposed that the Birds of the 
Canary Islands were identical with the Birds of Europe, or 
nearly so. Only a few well-marked species were allowed 
to be distinct from their European representatives'— 
Fringilla teydea, Columba laurivora, C. bollii , &c. 
Nowadays, however, all is changed, and a large number 
of the Canarian forms have been separated as subspecies. 
Herr von Thanner, who, we believe, is a resident in Tenerife, 
passed four months in 1909 in Grand Canary, collecting for 
Dr. Koenig, and now gives us some of the results of his 
observations, which are well worthy of study, though we may 
not accept all the subspecies which he recognises. In his 
list of 50 species, representatives of which Herr v. Thanuer 
collected or observed, no less than 23 have a third subspecihc 
name attached to them. These, however, have not, in most 
cases, been given to them by Herr v. Thanner, but by Koenig, 
Madarasz, Hartert, Polatzek, and other recent writers on 
Canarian Birds. 
26. Van Oort on new Birds from New Guinea . 
[Description of Eight new Birds collected by Mr. II. A. Lorenz in

Mus. xxxii. p. 211.] 
Mr. Lorenz has brought back a collection of nearly one 
thousand bird-skins from his successful expedition to the 
snowy mountains of New Guinea. A report on the whole 
collection will be published in a work called f Nova Guinea/ 
Meanwhile, Dr. Van Oort gives us descriptions of eight new 
species from the higher ranges. These are Anurophasis 
monorthonyx , gen. et sp. nov. Gallinarum ; Psittacella lorenzi , 
sp. nov., Poecilodryas quadrimaculatus , sp. nov.; Poecilodryas
