List of Plants and Insects of Surveyed Area. 



On account of the expense connected with the printing of long 

 lists of scientific names, it was necessary to omit from this paper 

 the detailed list of the plants and insects found or noted during the 

 survey. However a typewritten copy of this list together with a 

 'copy of this paper have been deposited in the library of The Ameri- 

 can Museum of Natural History, New York, N. Y.
