 Based on Cuvier's (1809, Ann. Museum, XIII, pp. 294-296, PL xix, figs. 4-5) 

 description and figures. Though currently accepted as the correct name of the 

 African manatee, Desmarest's name must be considered a homonym of Link's.

It is convenient to state at the outset my conclusion that Hartlaub 

 was quite right in the recognition of but three full species of manatees, 

 though geographical representatives may, in some cases, be worthy of 

 subspecific recognition. The correct names for these manatees are: 



Trichechus manatus manatus Linnaeus 

 Range. — The West Indies, the borders of the Caribbean Sea, the 

 coast and lower reaches of the rivers of northeastern South America. 



Trichechus manatus latirostris (Harlan) 

 Range. — The coast and coastal rivers of the United States from 

 Beaufort, North Carolina, to the Florida Keys and the coasts of the 

 Gulf of Mexico. 



Trichechus senegalensis Link 

 Range. — The west coast and coastal rivers of West Africa from the 

 Senegal to the Quanza, the upper reaches of the Niger, and probably 

 the Lake Chad drainage. (See pages 554 to 560.) 



Trichechus inunguis (Natterer) 



Range. — The rivers of northeastern South America, particularly 

 the Amazon and Orinoco systems. 



The only changes from the nomenclature applied by most modern 

 writers are the replacement of Trichechus senegalensis Desmarest, 1817, 

 by Trichechus senegalensis Link, 1795, and the adoption of latirostris 

 as a valid race of manatus instead of as a synonym of manatus or the 

 name of a species distinct from the latter.
