or over a portion of our- state. 1st. The Carolinian Zone, lying 

 mainly south of us, occupies a large section of the southeastern 

 and southwestern parts of the state, and is characterized by an 

 abundance of such birds as Tufted Tit, Cardinal, Acadian Fly- 

 catcher, Worm -eating Warbler, Yellow -breasted Chat, Louisiana 

 Water-Thrush, Kentucky Warbler, Carolina Wren and Blue-gray 

 Gnatcatcher. 2nd. The Alleghanian Zone, which meets the 

 Carolinian belt in the lower foot hills on the east and west oc- 

 cupies the whole of the Appalachian Mountains— except some 

 of the higher peaks and ranges—and spreads over perhaps two- 

 fifths of the state, including several counties lying west of the 

 mountains. Some of the characteristic birds of this belt are 

 Black-capped Chickadee, Wilson's Thrush, Chestnut-sided War- 

 bler and Rose-breasted Grosbeak. 3rd. Some of the high moun- 

 tain ranges and most of the northern counties lie in the Cana- 

 dian Zone and is the home of many birds characteristic of a more 

 northern latitude. Among them may be mentioned Blackburn - 

 ian Warbler, White-throated Sparrow, Winter Wren and Olive - 

 backed Thrush. 



About one hundred and sixty species and subspecies of 

 birds have been known to breed within the boundaries of Penn- 

 sylvania, and of this number the collection under consideration 

 embraces one hundred and forty varieties. These were carefully 

 selected from a large collection of series of sets of the various 

 species, and with the exception of the Birds of Prey, sets con- 

 taining as nearly as possible, the common type specimens were 

 used. In the selection of eggs of the Birds of Prey the largest 

 and handsomest sets were taken. Only one set of each species 

 was shown, as the space allotted to the exhibit would not per- 

 mit of a large collection showing the variations to which the 

 eggs of many species is subject. 



The collection was exhibited in connection with Dr. B. H. 

 Warren's collection of birds and mammals of Pennsylvania, and 

 was located in the eastern gallery of the Anthropological Build- 

 ing. Three cases, each eight feet long, were occupied by the 

 eggs which were labeled and arranged according to the classifi- 

 cation adopted by the American Ornithologists' Union. 



The * Catalogue of the Exhibits of the State of Pennsylvania 

 devotes several pages to this combination display, and in addi- 

 tion to a list of the species represented, says on page 164 under 

 the head of Miscellaneous State Exhibits.
