Mangusta Levaillantii, Smith, Zool. Journal, No. xvi. 

 Mangusta, penicillata, Cuv. Reg. Animal, 2d ed. 



Obs. This little animal is very common in the eastern districts of the 

 colony, and in 1826 was labelled in the South African Museum, by me, 

 as Le Vaillant's Mangouste. Mr. Ogilby however has the merit of bar- 

 ing discovered peculiarities in its structure which required it to be made 

 the type of a new genus, and he will doubtless be pleased to know that 

 its manners and habits are in support of the propriety of the separation. 

 The advantages of effectually commemorating the type of a genus, has 

 induced me in this instance, as well as in many others, to substitute for 

 the specific name applied in the first instance, one, which if continued, 

 yrill readily effect it.

Ohi. It might with justice and advantage be established as a rule, 

 that the second species discovered shculd bear the name of the indi< 

 Tidual who indicated the genus.
