rufous below than the female of C. s. sparverius, the outer rectrices, quill-markings 
and outer border of outer feather more rufous, the crown darker and with less or with 
no rufous. 
Type.— No. 108740, Am. Mus. Nat. Hist., % ad., La Manuelita (near Palmira), 
alt. 3500 ft., Cauca Valley, Colombia, April 12, 1911; F. M. Chapman and W. B. 
Richardson. | 
Range.— Western Colombia, from the western slopes of the Central Andes 
westward; south into subtropical and tropical western Ecuador (and western Peru’). 
Remarks.— This form is based on four males and five females. I also 
refer to it a male from Gualea, in the Subtropical Zone of Ecuador and two 
males from Huigra (alt. 4000 and 5000 ft.), in southern Ecuador. A male 
from the junction of the Chanchan and Chiguancay rivers, is nearer @qua- 
torialis in size but resembles cauce in color. | 
The Colombian males appear to be adult but all have the sides conspicu- 
ously spotted with black. Not one has the terminal white areas on the 
second or third outer primaries fused, while in fifteen of eighteen males 
of ochracea these markings are confluent. 
The male from Gualea, as the appended table of measurements shows, 
slightly approaches e@quatorialis in size, but although apparently adult, it 
has the sides heavily spotted; whereas, if I am correct in my assumption 
that the spots on the underparts of equatorialzs are due to immaturity, that 
form has the underparts with but few spots in the adult. 
Specimens examined.— Colombia: Laguneta, 1 2 ; Miraflores, 1 0,1 @ ; 
a Manuelita, 1-6, 1.9. Cah, lo: la Florida, 1 co’; Popayan, 1 9; 
Ecuador: Gualea, 1 0; Huiera, 2 oc}: Peru: lama, 1 2. 
Cerchneis sparverius equatorialis (Mearns). 
Falco sparverius equatorialis Mrarns, Auk, IX, 1892, p. 269 (“‘Guayaquil,’”’— 
errore — Ecuador). 
Char. subsp.— Size large; tail long; color much as in C. s. ochracea, but the sides 
in the male with usually a few, small elongate spots, the nape darker; terminal white 
areas in the second and third outer primaries usually fused. 
Range.— Temperate Zone in Ecuador and southward.! 
Remarks.— Insufficient material and the fact that both the male and 
female specimens designated by Dr. Mearns as types of this form are with- 
out locality, make it difficult to treat the Sparrow Hawks of Ecuador satis- 
factorily. 
- Since their measurements indicate that the types represent different 
11 have only two males from this zone in Peru, taken at Cuzco. They average larger 
than cinnamomina and have the underparts more deeply colored. They, however, agree 
with that form in having the underparts spotted and the tail tipped with rufous.
