162 BULLETIN OF THE 



in the vicinity of Jacksonville, at which point one of his assistants, 

 Mr. Charles Thurston, remained during April and a portion of May, 

 collecting, among other tilings, the later arriving birds. Nearly all the 

 birds ami mammals collected by these gentlemen, and by Mr. J. F. Le- 

 Baron, a third member of Mr. Maynard's party, have been added to 

 the collection of the Museum of Comparative Zoology, and are accom- 

 panied by measurements carefully taken before skinning. 



Mr. Boardman's observations were continued through three suc- 

 cessive winters, during which he spent considerable lime at the follow- 

 ing points : St. Augustine and Fernandina on the coast, Jacksonville, 

 Green-Cove-Springs and Enterprise on the St. John's River. Al- 

 though the numerous specimens he collected at these and intermediate 

 points were presented by him to the Smithsonian Institution, I am 

 indebted to him for an annotated manuscript list of the species he met 

 with. I am also indebted to the Rev. Thomas Marcy, who accompa- 

 nied me on my Florida trip, for valuable assistance in collecting, and to 

 Mr. J. E. Brundage for similar aid. 



Having made use of the reports of previous visitors on the faunae of 

 this region, the following lists are believed to embrace all the species 

 of mammals thus far known from East Florida, and all the birds regu- 

 larly present in winter, of nearly all of which I have examined speci- 

 mens from Florida. A few other birds not included in my list doubt- 

 less occasionally visit this region from the North, and others may lin- 

 ger here which usually pass the winter further south. In order to 

 increase the value of the bird li>t as a fatinal record, those species 

 known to be resident throughout the year have been indicated by 

 an asterisk (*), and those known only as winter visitors by an obelisk 

 (f). The date of the first appearance of the strictly spring visitors is 

 also noted, so far as such arrivals were observed. 



The specimens on which the investigations detailed in Part III are 

 based, as well as tin' revisionary notes of Parts II and IV, are mainly 

 those of the Museum of Comparative Zoology, which embrace, among 

 Others, nearly a thousand specimens of birds from Florida.* 



The topics discussed in Part III, namely, individual and climatic 

 variation, necessarily involve the question of the nature of species, 

 as well as the validity of various diagnostic characters. Many details 



* I have also made use of measurements, taken by Mr. Wm. Brewster and Mr. C. J. 

 M;iyiiurd, of hundreds of specimens not in the collection of the Museum.
