92. Langille on North- American Birds. 



[Our Birds in their Haunts : a popular Treatise on the Birds of Eastern 

 North America. By Rev. J. Ilibbert Langille, M.A, 8vo. Boston: 



1884.] 



The object of this work, as the author tells us, is to '' render 

 as popular and attractive as possible, as well as to bring 

 within a small compass, the sum total of the bird-life of 

 Eastern North America.''^ No systematic arrangement is 

 employed, but the narrative " follows in the main the order of 

 the seasons, and groups itself about certain interesting loca- 

 lities, such as the Niagara river and St. Clair flats." The 

 book is written " almost entirely from personal observation." 

 It is dedicated to Dr. Coues, whose scientific nomenclature 

 is followed throughout. 



93. Lawrence on new Species of Tyrannidse, Cypselidae, 

 and Columbidse. 



[Description of supposed new Species of Birds of the Families Tyran- 

 nidje, Cypselidae, and Columbidae. By George N. Lawrence. Ann. 

 N.Y. Acad. Sci. iii. p. 15G.] 



Mr. Lawrence describes in the present paper three sup- 

 posed new species from specimens collected in Yucatan by 

 Mr. Geo. F. Gaumer during his recent (second) expedition in 

 1884. These are Contopus albicollis, Chatura yucatanica, 

 and Engyptila gaumeri. Mr. Salvin [supra, p. 193) has 

 already stated his opinion that the last-mentioned specimen 

 is not different from E. Jamaicensis. 



94. Menzbier on the Blue Tits.

 anestes, Kaup). Par Michel Menzbier. Bull. Soc. Zool. France, 1884,
