Bulletin of the U. 8. National Museum. — The Bulletin of the National 

 Museum, the publication of which was commenced in 18 75, consists of 

 elaborate papers, frequently monographs of groups of animals, which 

 for special reasons it is considered more desirable to publish separately 

 than as papers in the "Proceedings." 



Five bulletins have been published duriug the year, aggregating 

 1.321 octavo pages of text, with 120 figures in the text and 240 plates of 

 illustrations. 



Bulletin 34; The Batrachia of North America, by E. D. Cope, was issued 

 July 6, 1889. It contains 525 pages of text, with 120 text-figures and 

 81 plates. This work is the result of an exhaustive study of the char- 

 acters of the species of Batrachians of North America, with their vari- 

 ations, and has been rendered effective by the very full collections in 

 the National Museum. A thorough discussion of the osteology of the 

 class is presented, based on material contained in various museums in 

 the United States and Europe. These results are expressed largely in 

 systematic form, in the belief, as the author says, that descriptive zool- 

 ogy will never be complete until the structure is exhausted in furnish- 

 ing definitions. Wherever practicable, reference is made to the relations 

 between the extinct and living forms. Many of the manuscript descrip- 

 tions used by Professor Cope in the preparation of this bulletin were 

 written by Professor Baird and Dr. Girard many years ago, with such 

 a publication as the present one in view. Some of the illustrations 

 were drawn by Professor Baird.
