In my paper describing some little-known Mammalia, in the first 

 volume of Charlesworth's ' Magazine of Natural History,' p. 579, 

 published in 1837, 1 used the forms and number of the pads on the 

 feet of Mephitis to divide it into three genera, and also showed the 

 importance of observing the size of the bald parts of the soles of 

 the feet in distinguishiug the species of Otters ; and in the ' Pro- 

 ceedings of the Zoological Society' for 1864 I have used the excellent 

 character which the form of the bald part of the sole affords for the 

 separation of the genera of Viverridoe. 



The only naturalist who seems to have followed up the subject is 

 Mr. Hodgson, who, in his paper " On the Tibetan Badger " in the 

 ' Journal of the Asiatic Society of Bengal ' for 1847, has given, in 

 t. 31, figures of the under part of the feet, showing the form and 

 disposition of the pads, of eight species of Indian Viverridce, Muste- 

 lidce, and UrsidcB.
