North America, C. frontalis, should be separated from that of the Pacific Coast-region, 
C. rhodocolpus, but it seems now to be generally admitted by American ornithologists 
that if there are two forms they pass insensibly one into the other. We have not 
nearly a sufficient series of skins of these birds to form an independent opinion, so we 
pass to what must ultimately be the technical result of the blending of the two forms 
and call them by a common name, C. frontalis. C. mexicanus of the Mexican high- 
lands we think we can distinguish, so we treat this form as distinct, at least until the 
barriers are broken down between it and C. frontalis and their differences are no longer 
capable of definition. 
C. frontalis is admitted into this fauna on the authority of Mr. L. Belding (we have 
no Mexican examples), who obtained specimens, determined as of the race rhodocolpus, 
at Guaymas®. But we are uncertain as to the correct position of the birds from Frontera 
and Monterey secured by the naturalists of the Mexican Boundary Survey. We have 
doubtfully referred them to C. mexicanus, but they may belong here. 
C. frontalis is a very familiar bird in the country in which it is found, frequenting 
houses as well as the open country. It has a pleasant song, and builds its nest in all 
sorts of places—trees, and crevices and ledges, in houses, a Swallow’s nest, in fact just 
as our Sparrow (Passer domesticus) does. The materials of its nest consist of grasses, 
with the lining of finer dried roots and hair. ‘The eggs are pale bluish marked, chiefly 
near the larger end, with specks and lines of blackish brown.
