The long-nosed Scolomys is a small rodent recorded from lowlands of northwestern South America and the western Amazon. Its short, broad head and nearly naked tail are distinctive.
The head is short and broad, with a pointed snout. The very short tail is nearly naked. The back ranges from reddish brown to dark reddish black, with black streaks.
In a study along the Juruá River in western Brazil, animals were caught in dense understory in undisturbed terra firme rainforest. The embryos recorded in pregnant females numbered 1–3.
