TURDUS MACULIROSTRIS. 
Dr. HELLMAYR gives a review of this species and its allies, 7. ignobilis, «с. (J. f. O. 1902, 
pp. 53-70). Не considers 7. maculirostris to be a good species, which never gets an entirely 
yellow bill, and is found in Western Ecuador. In the British Museum we have this form from 
Pallatanga and the Balzar Mountains.

TURDUS IGNOBILIS. 
T. IGNOBILIS is considered by Dr. Hellmayr to belong to a distinct group from T. maculirostris, 
which rather inclines towards 7. gymnophthalmus as its natural ally. Of T. ignobilis he recognizes 
four races, which after the manner of present-day nomenclaturists, he indicates as follows :— 
1. T. ignobilis ignobilis. Bogota. 
2. T. ignobilis goodfellowi. Салса Valley, Colombia, Castilla. 
3. T. ignobilis debilis. Е. Ecuador, Peru, and W. Brazil. 
4. T. ignobilis murinus. Guiana. 
The true T. ignobilis we have from Bogota and Antioquia. T. goodfellowi, Hart. & Hellm., does 
not appear to be in the Museum Collection. 7. debilis of Hellmayr we have from Xeberos, Yquitos, 
and the Lower Ucayali in Upper Amazonia, Guayabamba and Chirimoto in Peru, Sarayacu and 
Zamora in Ecuador. | 
The bird from Mapiri in Bolivia mentioned above (I. p. 240) has an entirely yellow bill, as stated 
by me, and it is certainly not 7. leucomelas, as Dr. Hellmayr suggests. lt may belong to a yellow- 
billed species, but the colouring recalls 7. debilis and 7. ignobilis.

TURDUS COLOMBIANUS, Hartert $ Hellmayr. 
Turdus columbianus, Hartert & Hellm. Nov. Zool. viii. p. 492 (1901). 
This species is said by the authors to be “ nearly allied to 7. nigrirostris, Lawr., from the West Indies, 
but differs in its smaller size, slender bill, and in the more rufous colour of the back." They 
add :—* It is perhaps of no more than subspecitic value, but as long as we are not acquainted with 
intermediate specimens, T. columbianus may stand as a species. Hellmayr has compared the type 
with specimens of 77. obsoletus, killed in April, September, and October. The example obtained by 
Mr. Stolzmann at Chimbo, N. Ecuador (cf. T. obsoletus, Tacz. & Berl. P. 7. S. 1883, p. 539; 1885, 
p. 122), apparently belongs also to this new species." 
Тһе type-specimen was obtained at Cali, Cauca Valley, Western Colombia, by Mr. W. F. 
H. Rosenberg.
