Description

The mountain spiny pocket mouse is a dark gray rodent with a white underbelly. The ears are black with white edging. The tail is black on top and at the base with a white underside (excluding the base) and a white tip. Collected adult specimens have ranged from 30.4 — 35.3cm long and weighted between 64.0 and 98.0g. The mountain spiny pocket mouse is distinguished from other Heteromys species by the bristles of its coat which are soft in H. oresterus but stiff and spiny in the other species.
