It will he observed that the ab()\c' list of fiflx-ninc sjjecies is com- 

 posed \cry hirgeK' of water-birds and a few others of more or less 

 general distribution in tropical America. Deducting the above from 

 the list of l)reeding species leaves fort>-one forms whose distriI)ution 

 within the group is more or less restricted, and these again may be 

 di\idcd into two cate ories. In the first are plced thirty-one forms 

 which arc in general confined to the more ndrthern and western 

 islands: 



Phalacrocorax aurilusfloridaniis 

 Geotrygon chrysia 



* Chcvmepclia passerina bahamensis 

 *Speotyto cunicidaria cavicola 

 *Saurothera bahamensis bahamen- 

 sis 



*Saurothcra bahamensis andria 

 * Dryobates villosus maynardi 

 *Dryobatcs villosus piger 



* Centurns nyeanus n yean us 



* Centurns nyeanus blakei 



* Centurns nyeanus bahamensis 



* Nesophlox evelyncE 



* Riccordia ricordii bracei 



* Riccordia ricordii ceneoviridis 



* Tolmarchus bahamensis 



* Blacicus bahamensis 

 Mimus polyglottos polyglottos 



* Minwcichla phtmbea 

 Sitta pusilla 



* Callichelidon cyaneoviridis 

 *Dendroica flavescens 



* Dendroica pityophila 



* Dendroica vigor sit achrustera 

 Seiurus aurocapillus 



*Geothlypis rostrata rostrata 

 *Geothlypis rostrata tanneri 

 *Geothlypis rostrata coryi 

 * Agelaius pha'niceus bryanti 

 *Icterus northropi 

 *Spindalis zena zena 

 *Spindalis zena townsendi 



Ten species, on the other hand, are more or less restricted to the 

 more southern and eastern islands, as follows: 



Sula cyanops 

 Sula leucogastra 

 Phalacrocorax vigua mexicanus 

 Oxyechus vociferus rubidus 

 Chccmepelia passerina exigua 



*Speotyto cunicularia bahamensis 



* Nesophlox lyrura 

 Tyrannus cubensis 

 Mimus polyglottos orpheus 

 Margarops fuscatus ftcscatus 



Of course, no hard and fast line, geographically speaking, can be 

 drawn between the Inaguan Fauna, as it may be called, and the 

 Bahaman Fauna proper, some species of each group having a much 

 more extensive distribution than others, resulting in an overlapping 

 of the two faunas in certain of the intermediate islands. Indeed, 

 three species, Chccmepelia passerina bahamensis, Nesophlox evelyncE, 

 and Mimus polyglottos polyglottos, might be referred to our first list
