CHAPTER XXV. 



WHALES AND MANATEES. 



(Cetacea: Sirenia.) 



WING to the enormous extent of coast-line belonging 

 to the United States, washed as it is by the Arctic 

 Seas, the Atlantic and Pacific Oceans, and the Gulf 

 of Mexico, it permits of adding to the fauna of the 

 country many of the order Cetacea, or those marine mammals 

 known as whales, dolphins, and porpoises. Outside of the few 

 who have especially studied these great oceanic animals, of more 

 or less fish-like form, it is but a limited number who realize how 

 numerous are the species we can lay claim to as having occurred 

 some time or other upon our coasts. 



Some years ago the United States National Museum of Wash- 

 ington, D. C., published a provisional list of these highly interest- 

 ing mammals, and this I here present, simply in order to give 

 some idea of what an extensive group the Cetacea really is :
