To anyone travelling or sojourning in Switzerland, we can 

 thoroughly recommend this work as a reliable guide, not 

 only to the birds but to the otiier groups of Vertebrates 

 inhabiting central Europe. 



Grinnell on a new Red-winged Blackbird. 



[A new Red-winged Blackbird from the Great Basin. By Joseph 

 Grinnell. Proc. Biol. Soc. Wash, xxvii. 1914, pp. 107-108.] 



Mr. Grinnell adds one more form to the large number of 

 already named subspecies of Agelaius phceniceus. He calls 

 it A. }j. nevadensis, and states that it inhabits the State of 

 Nevada and parts of north-eastern California which lie 

 between the Rocky Mountains and the Sierra Nevada, where 

 the climate is dry and desert-like. 



Mathews on Australian Birds. 



[The Birds of Australia. By Gregory M. Mathews. Vol. iii. pt. 6, 

 pp. 445-512, pis. 190-199 (June 1914) ; vol. iv. pt. 1, pp. 1-80, pis. 200- 

 209 (October 1914).] 



In these parts, concluding the Ardeiformes and proceeding 

 to the AnseriformeSj Mr. Mathews continues his careful 

 researches into the synonymy of the various forms, and, as 

 usual, gives an admirable summary of their life-histories, 

 for the elucidation of which he has been successful in 

 enlisting a still greater of correspondents. The illustrations 

 leave little to be desired. 



Only two new genera are proposed, and no new species or 

 subspecies, but our readers should consult in this connexion 

 the ^ Austral Avian Record ' and the author's last ' List of 

 Australian Birds,' besides 'Novitates Zoologicse.' The new 

 genera are Ctenanas for Leptotarsis Eyton, preoccupied 

 under the form Leptutarsus Guerin, and Hemigarzetta for 

 Herodias eulophotes ^winhoe; but the former had been more 

 doubtfully suggested in the Austral Avian Record (vol. ii. 

 p. 90). Mr. Mathews also accepts Radjah Rchb. for the 

 White-headed Sheld-Duck, and Casarca Bp. for the Mountain 

 Duck, giving in both cases the differences which he thinks 

 entitles them to be separated from Tadorna. Similarly he
