One specimen, similar to Guiana and Brazilian specimens, but the back distinct rufous brown without darker dots along the shafts. In this respect it resembles more T. leucauchen, Scl. (P. Z. S. 1855, pl. LXXIX.), which seems to be closely allied. This species has been overlooked by Dr. Leotaud, but is noticed from Trinidad by Mr. Taylor. FORMICARIIN^E. 46.

One specimen has the under tail-coverts dark chestnut, the other mixed with bright rufous feathers. Dr. Leotaud gives an excellent description of this species.
