. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Notes on Mastomys pemanus 227 All specimens with dry skin and skull with the exception of NHM (skin only). Measurement definition and descriptions follow Van der Straeten & Van der Straeten-Harrie (1977) and Van der Straeten & Dieterlen (1987). External body measurements were recorded from the specimen labels. External characters: The soft pelage has all characters mentioned by Rosevear (1969) as typical Mastomys. Kershaw (1921) gives a comprehensive and exact description of the skin. The hairs of the belly are grey with white tips giving the belly its greyish aspect. In most of the specimens the belly is slightly washed with buff and some specimens have a small completely white speck on the chest. There is a very prominent spot of white hairs behind the ears. Due to preparation, these characters are not so clear in the specimens of the KBIN. The hairs in the middle of the thickly clothed tail are 1,5 mm long. The mammary formula is not known, as the only female specimen is a juvenile. The specimen from Dakawa has some aberrant characters. It lacks an ochraceous stripe between the flanks and the underparts and has a 18,4 mm long foot, whereas the average footlength of the other adult specimens is 15,75 mm (15,00—17,00), n = 6. Measurements: see table 1. Skull: The anterior palatal foramina reach from just between the molars up to the beginning of the middle root of M1 and the palatine bone from the junction of M1 and M2 to the middle of M2, both as in typical Mastomys. The interorbital region also has the typical Mastomys structure. The mesopterygoid fossa is very narrow on the posterior margin of the palatine, becoming relatively wide towards the end; as a result this fossa has a triangular aspect (fig. la).
