Fig. 2: Gazella rußfrons, female from Bandiagara (photo by the author). Rodentia: Muridae: Gerbillinae Gerbillus cf. gerbilliis (Olivier, 1801) The species lives in the isolated soft-sand-belt southeast of the Falaise de Bandiagara (Teli, 29 December 1993, no. 1465; Tireli, 12 February 1995, no. 1787). Up to now it was known only from the North of Mali (Musser & Carleton 1993). On the leeside of the Falaise, sand from the northwind Harmattan falls down and fomis a narrow band of soft-sand-dunes of 50-200 m in diameter close to the cliffs. This is the only suitable habitat for the sand-dwelling species in the area. Measurements (no. 1465 o^, 1787 ?): HB: 93,90; T: 106, 110; HF: , ; E: , ; CB:-, Tatera guineae {lhom?iS, \9\Qi) A female was trapped in a thorn-scrub area near Bla (20 January 1994) (no. 1463 ?). Measurements: HB: 118, T: 179, HF: 34, E: 19, CB: , ZBr: Further specimens were found in the owl pellets (Tab. 1). Tatera cf kempi (Wroughton, 1906) One animal was found in an owl pellet in the Falaise de Bandiagara near Nombori. This constitutes the second record of the species for Mali (Wilson 1987). Taterillus ci. pygargus (F. Cuvier, 1838) A female was collected near Kemeni, Arrdt. Bla (21 January 1994). The animal lived in an area near a dry riverbed. The place was nearly without any vegetation except some sparse grass nests. As no chromosomal data have been taken the differentiation of T. pygargus and the following T. gracilis is based on the geograohic finding places. Measurements (no. 1464 ?): HB: 120, T: 151, HF: 28, E: , ZBr: Taterillus cf gracilis (Thomas, 1892) Two females were trapped in a hedge near Bandiagara, together with Mastomys cf. natalensis (15/16 February 1995). One animal (no. 1788) was carrying three embryos (2/(1)) with a crown-rump length of
