 R. Ridgway of the Smithsonian Institution, and J. A. Allen of 

 the American Museum of Natural History of New York, for loan of - 

 material for the identification of specimens, and to Mr. Witmer Stone 

 of Philadelphia, for the care of the collections during my absence, and 

 aid in their identification. I wish further to particularly acknowl- 

 edge the kindly loan of 200 specimens collected by my companions,
