Chemepelia rufipennis cauce subsp. nov. 
Chemepelia rufipennis rufipennis Topp (nec Bonaparte; Cauca Valley specimens 
only), Ann. Carn. Mus. VIII, 1913, pp. 586, 602. 
Char. subsp.— Male not certainly distinguishable from the male of C. r. rufi- 
pennis but averaging paler below and browner above; female conspicuously different 
from the female of that race; the upperparts rather light Saccordo’s umber, practi- 
cally without trace of vinaceous, except upon the rump and upper tail-coverts where 
it is much less pronounced than in C. r. rufipennis; the crown usually concolor with 
the back; the rectrices, upper wing-coverts and inner wing-feathers externally, the 
underparts, particularly the flanks and lower tail-coverts, with less vinaceous tawny 
than in C. r. rufipennis. 
Type.— No. 108688, Am. Mus. Nat. Hist. 9, La Manuelita, near Palmira, 
Cauca Valley, Col., April 15, 1911; F. M. Chapman; W. B. Richardson. 
Range.— Tropical Zone in the Cauca Valley (and arid upper Dagua Valley ?), 
Colombia; ranging upward to the lower border of the Subtropical Zone at about 
6300 feet. 
Remarks.— Four females from the Cauca Valley (Cali, La Manuelita and 
below Miraflores) and the slopes rising from it all show, on comparison with 
an-adequate series from Santa Marta, the excellent characters on which 
this form is based. 
THE Races oF LEPTOTILA RUFAXILLA. 
The name Leptotila rufaxilla (Rich. & Bern.) is currently applied to a 
common Dove which ranges over northern South America east of the Andes. 
In attempting, however, to identify our Colombian specimens, I find that 
our forty-four specimens of this species from north of the Amazon apparently 
represent no less than four forms of which two appear to be undescribed. 
This species has also been recorded from south of the Amazon, but 
beyond indicating that these records are not based on true rufazilla, my 
material from this region is too limited to warrant the forming of conclu- 
sions. |

Char. subsp.— Darker above (olive-brown with more or less iridescent natal-
