 several genera, vultures, caracaras, kites, barn and burrowing 

 owls, parrots, aiiis, ivory-billed woodpeckers; chuck-wills-widows, 

 cardinals, blue grosbeaks, yellow r -breasted chats, mocking birds,

Thirty out of the above 37 genera breed also in the West 

 Indies. 



No less than nine Tropical American genera of birds inhabit 

 the subtropical belt of Florida, namely, Zenaida, Geotri/yoit, 

 Stamcenatii Rostrhamus, Polyborus, Crotop/i</n. Euetheia, Oilli- 

 chelidon, and Cwreba. The following Antillean species and sub- 

 species occur in the same area and are not known from any 

 point further north: Colinm mrginianuB ctibanensis, ("olurnba 

 leucocephala, Zenaida zencdda, Gcotrygon martinica, Starnosncts 

 cyanocephala, Rostrhamus sociabilis, Falco dominicm#is, tfpcotyto 

 cunicularia floridana, Polyborus cheriway, Crotophaga ani, ("occyzut 

 minor maynardi, Agelaius phceniceus bryanti, Enetheui b (color, 

 Euetheia canora, Progne cryptolcuca, Pctrocliclldon _//(/rc/, CoJUi- 

 chelidon cyanoviridis, Vireo altiloguus ba/rbatuluSj Coereba baJm- 

 mensis. In addition to these species, the following are restricted, 

 so far as known, to southern Florida : Mdeagris gallopavo ow.nla, 

 Chordeiles virginiamis chapmani, Cyanocitta cristatct Jt&rincolo,,

That there are corresponding differences among insects is 

 evident from an important paper by Mr. E. A. Schwarz on 

 the Insect Fauna of Semitropical Florida. Mr. Schwarz states : 

 " I have come to the conclusion that it [the semitropical fauna 

 of Florida] is entirely of West Indian origin, and that the region 

 I shall hereafter circumscribe as Semitropical Florida does not 

 contain any endemic forms. In other words, the distinctive 

 fauna of southern Florida is a permanent colony of AVest 

 Indian forms, much more numerous in species than it has 



*The following 37 genera of birds breed in Florida, but none of them 

 range north to " frigid Canadd," though 30 out of the 37 are known 

 to breed in the West Indies: ( 'oil mi*, Meteqgris, Colwnba, Zenaidura,
