18 BULLETIN No. 32. 



November 14, 1896, thus bridging the gap between the summer 

 and winter observations previously made. Following this cal- 

 endar the author proceeds to discuss the general subject of 

 migration as illustrated by the movements studied , and to draw 

 a conclusion : " It is held that bird migration is a habit evolved 

 by education and inheritance which owe their origin and per- 

 petuation to winter with its failure of food." The last six of 

 the forty-five pages are devoted to an annotated list of the 

 forty-two species observed during this series of studies. The 

 paper is printed in large clear type on good paper, and the 

 typography is above reproach. — L,. J. 



Our Comino7i Birds. By C. F. Hodge, Ph. D. 



This is number 2, of the Biology Series of Nature Study 

 Leaflets issued from Clark University. It consists of thirt}'- 

 five pages and thirteen illustrations. The subject matter of 

 this leaflet is another of the earnest pleas for the preservation 

 of our native birds through the medium of education. The 

 suggestions for introducing the subject of bird study into the 

 school room as well as the out door studies, are admirable. 

 The birds are estimated at their true value, while sentimental 

 exaggeration is absent. The pages are plentifully sprinkled 

 with apt quotations of prose and verse, and frequent direct 

 references to careful investigations by experts, and, foot notes 

 add value to the paper. It is a leaflet which teaches of Nature 

 Study in schools would find useful. Prof. C. F. Hodge, Wor- 

 cester, Mass., is prepared to supply copies at five cents each.

Notes on Birds Collected by Doctor W. L. Abbott in Central 

 Asia. By Harry C. Oberholser. From the Proceedings of 

 the U. S. National Museum, Vol. XXII, pages 205-228. (No. 

 1195). 



This collection of 142 specimens, representing sixty-two 

 species and twenty-three families, was collected by Dr. Abbott 

 in Cashmere and Ladak in 1895 and 1897- The annotations 

 give the altitude range of most of the species, with some 

 notes on plumage and habits. We notice that the systematic 

 arrangement departs from that adopted by tlie American 

 Ornithologist's Union committee, following instead the British 

 system, which appears to us the more logical. — L. J.
