COMMENTS: Subgenus Nannomys . In body size and morphology, M. bufo superficially resembles the large-bodied M. triton , but the two are distinguished by dental features and tail length ( Petter and Matthey, 1975) as well as karyotypes ( Robbins and Baker, 1978), and both occur together in the Kivu region of E Zaire (specimens in the American Museum of Natural History). Chromosomal data for Burundi samples reported by Maddalena et al. (1989).
