North America, C. frontalis, should be separated from that of the Pacific Coast-region, 

 C. rJiodocolpus, 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.
