The Manatees and their alhes are now hichided in the Cetacea [cf. 

 Ilhger]. 



The general impression of this classification is that it is conservative 

 in form but transitional and confused in principle. Cuvier's former confi- 

 dence in the worth of the general characters of the extremities as primary 

 ordinal criteria had evidently been shaken as shown by the substitution of 

 "Insectivores" for "Plantigrades," of "Marsupiaux" for "Pedimanes," 

 by the reduction of "les Solipedes" to subordinal rank, by the association 

 of odd- and even-toed forms under "les Pachydermes," etc. The numer- 

 ous supposed transitions from Carnivores to Marsupials, from Marsupials 

 to Rodents, and from Edentates to Monotremes and even Ungulates, are 

 stated, but also the opposing views of the total distinctness of the INIarsupials 

 and of the Monotremes.
