In spite of the late Dr. Sharjae's doubts there can be no 

 question that T. t. dagihce is a perfectly distinct form, though, to 

 my mind, its relations are more correctly exjaressed by a trinomial 

 appellation. Compared with a good series of T. tristis cnej^hosa 

 Bangs, from Ohiriqui and Western Costa Rica (Miravelles), the 

 Colombian birds have shorter wings and tail, a much shorter, 

 slenderer and darker (blackish-brown) bill, and difler also in 

 coloration. The upper parts are deep reddish sepia-brown (instead 

 of greyish olive or olive-brown), the breast and sides dark 

 rufescent brown (instead of pale brownish grey), and the sides of 

 the head deep sepia-brown (instead of sooty black). 



T. t. daguce is peculiar to Western Colombia and N. W. Ecuador, 

 whence Miketta and Flemming sent numerous specimens to 

 Mr, Rosenberg. Ecuadorian skins are practically identical with 

 the topotypes forwai'ded by Mr. Palmer. This Thrush is an 

 inhabitant of the humid lowlands and does not occur in the 

 mountainous parts of the interior.

Identical with other specimens from Bogota, Ecuador, and 

 Venezuela (Merida).
