Following out these lines the author presents a number of interesting 

 ami readable chapters describing the beauties of field and forest in his 

 State; fishing and hunting experiences and anecdotes of white man and 

 Indian; and through it all is brought out the necessity for united effort in 

 cultivating a proper appreciation of nature and in saving the wild life from 

 rmination. Beside chapters on Water-fowl and Wild Turkeys there 

 is a ' tentative list ' of the birds of Oklahoma compiled by Prof. George W. 

 Stevens of t he Northwest Normal School and Oklahoma Geological Survey, 

 which consists of 227 species with brief notes as to the character of their 

 occurrence. This we believe constitutes the first Oklahoma ' state list.' —

Craig on the Stimulation of Ovulation in Birds.' — Largely from a 

 Study of pigeons the author finds that egg-laying can be induced without the 

 true sexual stimulus and comes to the conclusion that it is the result not of a 

 Bingle .stimulus but of a complex in which environmental conditions play 

 an important part. He cites the mating of two female pigeons with ovu- 

 lation by both, and the influence of the nest and eggs in restraining the 

 incubating pigeon from further sexual activity, in presenting his conclu- 

 sions. — W. S. 



Laubmann on Birds from Thian-Schan. 2 — This paper is based upon 

 a collection of 1234 skins obtained by Dr. Gottfried Merzbacher in the 

 Thian-Schan Mts., Turkestan in 1907-8. 198 species are listed with notes 

 as to their relationship, distribution, etc. and synonymic references to other 

 papers dealing with the same general region, a list of which is given in a 

 bibliography. No new forms are described, but the paper forms a valu- 

 able contribution to the ornithology of the Chinese Empire. — W. S. 



Stresemann, on East Indian Birds.' — Mr. Stresemann in a recent 

 contribution to the ' Novitates Zoologicae ' continues his miscellaneous 

 notes on [ndo-Australasian birds. These are as follows, numbering con- 

 tinuously with his previous instalment. XIX. The forms of Artamus leu- 

 corhynchos (L.); A. I. humei subsp. n. from the South Andamans. XX, 

 Some forms of Hypothymii azurea (Bodd); H. a. symmixta Alor Island,
