 The "Bellua?" of Storr thus includes the same assemblage as the "Pachy- 

 dermes" of Cuvier. 



1779. Blumenbach (p. 46, above) distributes the ungulates in the 

 orders Solidungula, Bisulca, Belkue. 



1792. Vicq d'Azyr (p. 55 above) dividing the mammalia into 15 "pri- 

 mordial groups," distributes the ungulates as follows: 



9. Chevaux d'eau. Hippopotamus. 



10. Elephans. 



11. Tapiriens. 



12. Porcini. 



13. Ruminans. ' 



14. Solipedes. 



1795. Geoff roy and Cuvier (p. 58 above). 



Ordre X. Pachydermes. Elephantus, Rhinoceros, Hippopotamus. Tapir, 

 Sus. 

 Ruminans. [Ti:ie Ruminants.] 

 Solipedes. Equus. 



This seems to be the first use of the term "Pachydermes," which, as 

 noted above, is practically synonymous with Storr's usage of "Belluse." 



1800. Cuvier (p. 66 above). In this classification the number of digits 

 is again emphasized as a basis of classification.
