Descriptive notes. Head-body 109-118 mm, tail 55-60 mm, ear 17-18 mm, hindfoot 27-28 mm; weight 53-5-60 g. The Chilean Long-clawed Mouse is medium-sized and mole-like, with elongated front claws (more than 6 mm), thick pelage, and short tail; fur is long, soft, nearly uniform grayish brown above, and grayish white below; chest has brown mark; and tail is uniformly brown.

Habitat. Probably originally associated with arid Mediterranean thornscrub, an environment almost eliminated by human modification; reported in dense mesophitic forest and shrubby coastal areas; one individual was captured between shrub and cactus at the foot of a long steep slope. Recent records of the Chilean Long-clawed Mouse were obtained in dense thickets of the thorny bush Trevoa trinervis ( Rhamnaceae ) on eastern slope of Chilean coastal range in central valley of Chile.

Status and Conservation. Classified as Near Threatened on The IUCN Red List.
