303:. The upperparts are yellowish brown, becoming lighter towards the sides; this coloration is sharply delineated from the whitish underparts. The external ears (pinnae) are small and rounded and have a patch of white hair behind them. The tail, which is dark above and white below, is relatively short. The feet are fairly long and narrow and are covered above by white hairs. In two specimens from Capitão Andrade, the head and body length is 86 to 112 mm (3.4 to 4.4 in), the tail length is 75 to 85 mm (3.0 to 3.3 in), the hindfoot length is 21 to 22 mm (0.83 to 0.87 in), the ear length is 16 to 18 mm (0.63 to 0.71 in), and the body mass is 25 to 35 g (0.88 to 1.23 oz).
