In two skins from Parida Island on the Pacific coast of western Panamé 
one measures 276 and one 290 mm., while three from nearby Gober- 
nador Island range from 256 to 272. The great variation in size in 
this bird is evident from these figures. 
Herpetotheres cachinnans quervbundus Bangs and Penard: 
Herpetotheres cachinnans queribundus Banes and Penarp, Bull. Mus. Comp. 
Zo6l., vol. 68, 1919, p. 23 (Pernambuco, Brazil). 
Similar to cachannans, but more grayish brown above; similar also 
to chapman, but more grayish above; light areas averaging whiter, 
with less buff than in the other two races. 
Range: Kastern Brazil and eastern Bolivia south to the Territory 
of Chaco and Corrientes, northern Argentina. 
The southern form has the wing about as in the typical form in 
Brazilian examples, but in the southern part of its range averages 
larger. Birds from Brazil have the wing 266 to 273 mm., one from 
Bolivia measures 263 mm., and skins from Paraguay and Argentina 
vary from 289 to 299 mm. The “type” locality through the chance 
of the original description has been set in a region where approach to 
cachinnans begins, as I consider that larger size and paler color are 
the characters of this race. These have their maximum development 
farther south. 
MICRASTUR RUFICOLLIS INTERSTES Bangs 
Micrastur interstes Banes, Auk, 1907, p. 289 (La Estrella de Cartago, Costa Rica). 
On November 14 in the heavy forest of Cerro Santa Maria I shot 
a male of this hawk as it came flying in to rest on a low perch and peer 
about while I was trying to decoy some small birds. This individual 
had the tail in molt. 
FALCO SPARVERIUS SPARVERIUS Linnaeus: Northern Sparrow Hawk 
Falco sparverius LINNAEUS, Systema naturae, ed. 10, vol. 1, 1758, p. 90 (South 
Carolina). 
In open fields around Liberia, and in the pasturelands of the Hacienda’ 
Santa Maria, the sparrow hawk was common from October 18 until 
my departure. One was seen near San Ramon on October 16. From 
this it appears to be an early arrival from the north in fall. It is” 
called chameleén by the country people. The two taken are of the 
typical form.

On my first day afield at the Hacienda Santa Maria in the dense 
forest above the house I encountered a small flock of these wood-quail
