Under the name Micronesia the author designates the 

 Pacific Islands lying between 130° and 180° W. long., i. e. 

 the Pelew Islands^ Yap, the Mariannes, and the Carolines. 

 After quoting Wiglesworth's ' Aves Polynesise/ he mentions 

 recent additional authorities on this A\'ifauna and discusses 

 its various relationships. Most of the genera not endemic 

 are apparently Papuan, Tables of distribution arc given, 

 and it is shown that Micronesia may be divided into five 

 smaller Avifaunas — Pelews, Yap, Mariannes, and Western 

 and Eastern Carolines. 



The same subject is pursued in the popular article in 

 Westermann^s 'Illustrirte Deutsche Monatshefte,^ and i.s 

 illustrated with figures of some of the more remarkable birds 

 of Micronesia, and with a map, which shews the proposed 

 divisions of its Avifauna very plainly.

 Kasuare. Von Paul Matschie. J. f. O. 1901, pp. 265-269.] 



The publication of Mr. Kothschild's elaborate memoir on 

 the Cassowaries in the ' Transactions of the Zoological 

 Society of London ' has induced Herr Matschie to prepare 

 a series of notes on various points in the distribution and 

 systematic arrangement of these birds. Amongst these he 

 calls attention to the fact that the figures given by Mr. Roth- 

 schild of Casuainus uni-appendiculatus do not agree accurately 

 with Blyth^s original description of this species. Herr 

 Matschie therefore believes these figures to represent a
