THE LONG-NOSED AGOUTI. 
Dasyprocta Aguti. Illig. 
The Agoutis and Pacas were first separated by M. F. 
Cuvier in the Dictionnaire des Sciences Naturelles in 
the year 1806 ; but by some oversight he then neglected 
to distinguish the former by a generic name. In 181], 
Illiger supplied this deficiency by applying to them the 
term Dasyprocta, for which M. F. Cuvier has since 
endeavoured to substitute that of Chloromys. We are 
compelled, however, while we acknowledge that the 
genus was of his formation, to reject his name and adopt 
that of Illiger, which has the unquestionable advantage 
of priority. When a right of this description has been 
waved in the first instance, and subsequently exercised 
by another, it cannot be resumed by the original pos- 
sessor without creating that confusion in nomenclature
