Praomys morio (Trouessart, 1881) . Bull. Soc. Etudes Sci. Angers, 10:121.

TYPE LOCALITY: Cameroon, Mt. Cameroon, 7000 ft; see Rosevear (1969:399) .

DISTRIBUTION: Mt. Cameroon.

SYNONYMS: maurus (of Gray, 1862, not Waterhouse, 1839).

COMMENTS: A member of the P. tullbergi complex. We restrict P. morio to Mt. Cameroon, although Eisentraut (1970) recorded it from Bioko, and Petter (1965) discussed samples from the Central African Republic. The species requires definition; alledged distinctions between it and P. tullbergi may not reflect specific differences (Hutterer, in litt.). Our study revealed that series from outside of Mt. Cameroon identified as morio are either tullbergi or an undescribed species of Praomys (the series from Central African Republic, for example).
