While the collection is fairly representative, it is probably 

 by no means complete, as it was made at odd times when oppor- 

 tunity offered, our main object beins, r the collecting of birds, 

 mammals and botanical specimens. 



The identification of the specimens, which constitutes the 

 'real value of the paper, is entirely the work of Dr. Henry Skin- 

 ner, to whom my sincere thanks are due. My contribution con- 

 sists merely of the field notes. The entire collection of several 

 hundred specimens has been presented to the Academy of Xat-
