(1862) H. linteatus. v Tail of Heterocercus linteatus from beneath. This is a very singular type, remarkable for the peculiar form of the tail and the nearly smooth rictus.

The three known species of Heterocercus are confined to the forests of Amazonia. Key to the Species. A. Sides of head black; coronal patch 1. linteatus, p. 824. B.
