Report on the Reptiles and Batrachians of North America. — The Smith- 

 sonian Institution may claim the credit of having done more than any 

 other organization or any individual in furnishing to the students and 

 naturalists of the country convenient and effective text-books for the 

 determination of the natural history of the United States and North 

 America. In proof of this itis suflScient to point to what has been done 

 in the way of systematic treatises on mammals, birds, fishes, certain 

 groups of mollusks, &c. 



Although a number of monographs of reptiles have been published 

 more or less directly under its auspices, such as that of the serpents 

 and other groups, there is still lacking a compact manual of both the 

 reptilia and batrachia ; and arrangements were accordingly made with 

 Professor Cope, of Philadelphia, to supply this want. This gentleman is 

 well known for his professional acquaintance with these groups as studied 

 by him in the collections in the Museum of the Academy of i^Tatural Sci- 

 ences of Philadelphia, the National Museum of Washington, and else- 

 where. An agreement was therefore made with him for the preparation 

 of a much-needed manual on the reptiles and batrachians of North Amer- 

 ica ; a year's time being allowed, at a suitable compensation, for the final 

 and critical examination of the collections of the National Museum and 

 the preparation of the report. In this way the entire field of the ver- 

 tebrates of North America will have been completely covered. 



Proceedings of the National Museum. — This series, somewhat allied to 

 the series of ''Bulletins," comprises papers relative to the collections —
