Diagnosis

Reference	Diagnosis
D. M. A. Bate 1942	A Rattus about the size of R. norvegicus. Zygomatic plate not thrust far forward as generally in Recent Rattus ; distance from anterior border of alveolus of M1 to anterior basal angle of zygomatic plate very short, equalling about two-thirds of the length of M 1 ; anterior ascending border of plate slightly receding, posterior border short, anterior base of plate unusually low. Cheek-teeth narrow, M1 three-rooted, internal tubercles not strongly salient, anterior root not projecting forwards above the alveolar border. t3* is present in M 2 ; the maximum length of M 3 is about half that of M1
