plying of important data. In the division of reptiles and batrachians

 nection with studies of fossils; Remington Kellogg has continued 

 his work on an economic and systematic study of the toads ; Dr. G. K. 

 Noble has paid special attention to the frogs of the Dominican 

 Republic and has borrowed some of our material ; K. P. Schmidt 

 has written some interesting reports on the herpetology of Lower 

 California, making use of our collections; A. I. Ortenbnrger has 

 identified snakes, and Dr. E. R. Dunn has identified salamanders. 

 Dr. Henry W. Fowler has cooperated with Mr. Bean in preparing a 

 report on the fishes of the Wilkes Exploring Expedition.

 here. The following names may be mentioned in this connection:
