geographic variation, individual variation, distribution and life-history, 

 the last including field notes by Prof. Muller. There are also a bibli- 

 ography and a historical introduction, an annotated list of Macedonian 

 birds not contained in the collection and finally a nominal list of the 261 

 species recorded from the country with page references to the main text. 



The study of the collection has been carried on with great care and a 

 vast amount of detailed description and measurements is presented. The 

 attention that has been given to the molts and plumages is deserving of 

 especial commendation and it will interest American ornithologists to 

 know that the comprehensive terminology proposed by Dr. Jonathan 

 Dwight in this connection has been largely followed. 



The nomenclature is up to date in every respect and includes references 

 to the original description of every species as well as to the subspecies 

 where it does not happen to be the "typical" race. 



We notice only two new names proposed by the author: Galerida cris- 

 tata muhlei (p. 62) for Alaiida ferruginea Miihle 1844 (nee A. ferruginea 

 Smith 1830); and Budytes flavus macronyx (p. 76), a new form from Vladi- 

 vostok allied to B. f. thunbergi. 



There are eight excellent views of Macedonia reproduced in half-tone 

 and a number of diagrams showing variation in wing length in various 

 species. 



Dr. Stresemann is to be congratulated upon producing a report that 

 is a model of its kind and in providing us with a thoroughly up to date 

 work of reference upon the avifauna of a country about which we knew 

 but little.— W. S. 



Wood on the Eyes of the Burrowing Owl. — Dr. Casey A. Wood 

 has published a valuable paper on the eyes of the Burrowing Owl 1 with 

 a full technical description of their structure compared with that of other 

 owls and a plate of the fimdus oculi. 



His conclusions are of especial interest to ornithologists. He says: 

 "In spite of the fact that Bendire and Hudson refer to the animal as a 

 diurnal owl, their accoimts of its habits really bear out the writer's con- 

 tention of a nocturnal animal with fairly good day vision, yet distinctly 

 embarrassed, uncertain, and confused when the eyes are exposed to bright 

 sunlight. Stress is laid by a number of observers upon the fact that 

 this owl is seen at all times of day standing guard often on a little mound 

 of earth in front of his burrow entrance, forgetting that as a much more 

 interested householder, he also watches from the same post all hours of 

 the night." Dr. Wood finds the eye structure similar in every respect 

 to that of nocturnal animals.
