Having only three European examples of (Eik- mia before us, the material at our loniinand for a satisfactory comparison with (K. amerkana is not a>< extensive as could be desired. Two of these specimens, a male and a female received from Schliiter, appear to be the genuine (E. nigra, since they differ very decidedly from all American speci- mens ; but the third, an adult male (No. 15584, Feb. 8, 1844), from Baron von Miiller, is entirely identical with the American bird, and may be an American specimen. Setting aside this latter ex- ample, the diffi-runces between the two species are very obvious, consisting of the following points : The male of CE. nigra has the bill black, including the basal knob, the culmen having a shiehl-shaped patch of yellow, extending back to the base of the knob, and reaching forward neai'ly to the nail ; the end of the bill is altogether more depressed than in (E. aviericana, the top of the nail being nearly Hat, instead of very strongly convex. The female also the bill conspicuously flattened terminally, as in the male, and also at the base, the maxilla Ixjing only about .55 instead of .70 deep. (See accompanying outline figures of the maxillx- of the females of the two species.) There is scarcely any difference in plumage, in either sex, between the two Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Baird, Spencer F. , 1823-1887; Brewer, T.
