TURDUS IGNOBILIS, Sel. 
COLOMBIAN DUSKY THRUSH. 
Turdus ignobilis, Sclater, Р. Z. S. 1857, р. 273; Seebohm, Cat. Birds Brit. Mus. v p. 214 
(1881). 
T. plagà gulari albá nullá: pectore et corporis lateribus cinerascenti-brunneis: gutture quoque cinerascente, 
obsoleté brunneo striato : rostro nigricante. 
ALTHOUGH in some respects closely allied to T. leucomelas and T. maculirostris, the Colombian 
Dusky Thrush must be recognized as a distinct species. It is to be told by its dingy throat from 
both of the above-named forms, as the characteristic dark streaks, very pronounced in 7. leucomelas, 
less so in T. maculirostris, become almost obsolete in 7. ignobilis. Added to this character, there is 
а second one of prime importance, viz. the black bill. This never seems to get yellow, and in the 
Salvin-Godman Collection is a breeding female procured by Salmon at Medellin, * with eggs." This 
has a black bill, and practically proves that 7. ignobilis never has a yellow bill in the breeding- 
season. 
The range of the species seems to be confined to Colombia. The type came from Bogotá, and 
Salmon obtained specimens from Antioquia (Scl. € Salv. Р. Z. S. 1879, p. 491). All the references 
to 7. ignobilis from other localities undoubtedly belong to some other species. 
A female from Medellin in the Salvin-Godman Collection measures as follows :—Total length 
9:3 inches, culmen 0:8, wing 4:69, tail 5:7, tarsus 1:25. (К. B. 5.]
