_I have two specimens of a Bogota thrush allied to 7. fumigatus, 
Licht., which I cannot yet satisfactorily determine. 
169. Turpus minimus, Lafr. R. Z. 1848, p: 5. 
Prince Bonaparte considers this the same as the northern T. minor 
(Notes Orn. p. 26, note). 
' 170. Mimus 
I have a Bogota skin of a bird of this difficult genus, possibly re- 
ferable to M. colombianus, Cab. or M. melanopterus, Lawrence.

176. CoamM&ZA MARGINATA (Max.)? 
A single skin in the British Museum does not seem distinct from 
Brazilian specimens. It may perhaps be more strictly referable to 
the Peruvian C. olivacea, Tsch., with which I am not acquainted.

178. Formicarrius niGrirrons, Gould, P. Z.S. 1855, p. 68. 
Very similar to Formicarius cayanensis, Bodd. (Pl. Enl. 821), but 
with a permanent black front.

A Bogota skin in the British Museum is identical with a type- 
specimen of Tschudi in my own collection, but I rather doubt whether 
Tschudi has rightly assigned it to d’Orbigny’s Bolivian species. 
181. ConopopHaca NANA (Lafr.).—Grallaria nana, Lafr. R. Z. 
1842, p. 334.—(Mus. Bnit.) 
Seems more of a Conopophaga than a Grallaria, as placed by 
Lafresnaye.
