Cory on American Birds. 



[Catalogue of Birds of the Americas. Part II. No. 1. By Charles 

 B. Cory. Publ. Field Museum Nat. Hist., Zool. Ser., Chicago, xiii. 

 1918, pp. 1-315 ; 1 pi.] 



It is the intention o£ Mr, Cory to catalogue all the birds 

 of the New World from Alaska to Cape Horn, and the 

 present volume, though not the first in classification, is the 

 first in time to appear. It deals with the Owls, Parrots, 

 Nighthawks, Swifts, and Humming-birds and their imme- 

 diate allies, and forms a stout volume of over 300 pages. 



The classification follows generally the lines laid down in 

 Sharpens Hand-list, and the nomenclature and arrangement 

 is based largely on Eidgway's ' Birds of Middle and North 

 America,' and on Brabourne and Chubb's ' List of the 

 Birds of South America,' though differing from the latter 

 work in the adoption of a trinomial grouping of the species. 

 Where any species is not described in Kidg way's great 

 work or in the Catalogue of the Birds in the British Museum, 

 a short definition of the species or subspecies is given in a 

 footnote, thus enabling a worker to identify any American 

 bird hitherto described with the aid of the three works. 

 Full references are given to tlie original descriptions of 

 both genera and species as well as to such works as contain 

 coloured plates or monographs of groups or important 

 papers on geographical distribution and taxonomy. There 

 can be no doubt that Mr. Cory's Catalogue will be of the 

 greatest value to all writers on American ornithology, and 

 we are greatly indebted to him for having undertaken so 

 laborious and useful a task. 



We find the following new forms characterized for the 

 first time, and would suggest that in future parts or volumes 

 a list of these should be prefaced to the beginning of the 

 work as it is difficult to disinter them : — Speotyto cuni- 

 cularia minor, Aratinga cactorum perpallida, Eupsittula 

 pertinax margaritensis, Amazona amazonica tobagensis, 

 Urospatha martii olivacea, Nephoeceies niger guadeloupensis, 

 Lepidopyga goudoti zuUcb, Colubri iolatus hrevipennis. 



The misprints appear to be rather more numerous than
