Morphological characters

Five specimens of a rather large Mus ( Nannomys) species have been captured on Mt Oku. Only one individual was previously collected at Lake Oku at 2100 m ( Eisentraut 1968). Owing to a HF length greater than 15 mm and their short tail, the new Oku specimens fall within the range variation of M. setulosus , whose holotype is from Limbé (Victoria) in SW Cameroon. Two of our new specimens were captured at an altitude of 2550 m on the Oku slope, while the others (three) were brought in by local people. The species is also reported from Manengouba crater lake ( 1800 m), from Mt Cameroon at 2200 m and from the Gotel Mountains around 1900 m ( Eisentraut 1973; Hutterer et al. 1992). The morphological variability of this species is not well known but the five newly collected Oku specimens have a longer tail than other CVL specimens ( Table 9). Their skulls and molars display the typical features of M. setulosus .
