unnumbered, 1827. 
Type: Rattus donovani, from the Cape of Good Hope. Description (genus): 
'* Upper fore-teeth cuneated; grinders three, rarely two each side each jaw; 
clavicles or collar bones perfect." (Species): ‘‘ Tail moderate and somewhat 
hairy; body varied with fuscous, black and cinereous, and three pale dorsal

Rattus Donovan antedates Arvicanthis Lesson, 1842, and is entitled to recognition 
if Rattus Frisch, 1775, is not a valid name. Donovan does not appear as the 
author of the genus in the description, but he was editor of the Repository.
