to northwestern Colorado in 1909, under the auspices of the University of 

 Colorado Museum, chiefly in Garfield, Rio Blanco, and Routt counties. 

 As the work of the expedition was mostly done between 5,500 and 8,000 

 feet altitude, very few alpine forms are recorded. A large number of 

 the species are entered on the authority of Mr. R. S. Ball of Meeker, who 

 has a private collection of birds and mammals. This number of the 

 'University Studies' (pp. 101-153, with numerous illustrations) is devoted 

 to an account of this expedition, and consists of ten papers on different 

 subjects including itinerary, climatology, botany, mollusks, insects, 

 vertebrates, fossil plants and fossil invertebrates, and a bibliography of 

 the geology and natural history of the region, the reports on the birds and 

 mammals being by Mr. Felger. The expedition was under the direction 

 of Prof. Junius Henderson, and appears to have been fruitful in results. —

Wood on Bird Migration at Point Pelee, Ontario, in the Fall of 

 1909.1 — This is a detailed daily record of observations made from September 

 14 to October 16. The advantages of Point Pelee as an observation point 

 for bird migration is due to the fact that here "the migrating hords are 

 concentrated in a small area that can be readily covered by a single ob- 

 server." The observations are given in the form of a diary, noting the 

 changes from day to day in the relative abundance of the prevailing spe- 

 cies. The great fall flight of hawks passed this point mainly during 

 September 18, 19, and 20.— J. A. A. 



Jouy on the Paradise Flycatchers of Japan and Korea.- — As ex- 

 plained in an introductory note by Dr. Stejneger, this is a fragment of man- 

 uscript left in his hands, with other memoranda and note-books, by the late 

 Pierre Louis Jouy shortly before his death in 1894, with the request that 

 Dr. Stejneger should work up his collection of Korean birds and publish 

 the results. This having proved impossible of accomplishment owing to 

 the pressure of other duties, the present paper, nearly as left by Mr. 

 Jouy, is now published, and serves to indicate how elaborately he had 

 planned the work. 



The two species here treated are Terpsiphone atrocaudata (Eyton), 

 found in southern Japan and southern Korea, and Terpsiphone oivstoni 

 sp. nov., inhabiting Hondo Island and parts of China. The descriptions 

 are very detailed, and accompanied by extensive tables of measurements. 

 Dr. Stejneger explains in a footnote the use of Terpsiphone in place of 

 Tchitrea, under Article 30 of the International Code of Zoological Nomen- 

 clature. — J. A. A.
