CHAPTER XIII 



DISTRIBUTION OF THE CETACEANS AND 

 SIRENIANS 



In a previous chapter on this subject (Chapter VIIL, p. 197) 

 I have already stated the principal facts known respecting 

 the distribution of these two marine orders of mammals 

 and need not now repeat them. But I append a list of 

 the genera with the approximate numbers of the generally 

 recognized species and some general indications of their 

 ranges, and I add some general deductions. 



Table of the genera of the Order Cetacea, showing the 

 approximate number of valid species and their distribution.
