 of scapulars and llauk featliors. and concealed portion of greater coverts, deep black ; pri- 

 maries blackish dusky: tail dull slate; sides of the anal region behind the Hanks clouded 

 with grayish. Bill black; iris bright yellow: feet orange -yellow, with dusky webs. A'lull 

 female: Similar to that of (;. islandicn, but head and nock hair-brown or grayish brown, 

 rather than purplish sepia or snuff-brown; and white on the wing usually not interrupted 

 by a di.stinct black bar. 



Jiowny uouiifj. Upper parts generally, including the whole upper half of the head, to 

 the rictus, and considerably below the eyes, the chest, sides, and thighs deep sooty brown, 

 lighter and more grayish on the chest ; the bro\vn of the upper parts relieved by about eight 

 spots of grayish white, as follows: one on the posterior bonier Isocondary region) of eai'h 

 wing; one on each side the back; one on Ciich side the rump, at the base of the tail; and one 

 on eaeh Hank just before the brown of the thighs. Chin, throat, and cheeks pure white, in 

 abrupt and decided contrast to the brown, which entirely surrounds it: remaining lower 

 parts grayish white. Bill brownish; nail yellowish.

As stated under the hftad of G. ixlandicu (p. 109), wc arc un- 

 able to discover, in the material at our command (consisting- 

 of ujiward of twenty specimens, including six unquestionable O. 

 Ulatidica and many more equally undoubted 6'. c/«m(/«A< ainerkanx) 

 positive points of distinction between the female of the common 

 and that of Harrow's Golden-eye. All specimens, however, pos- 

 sessing no dusky bar across the ends of the greater wing- 

 coverts, interrupting the white wing-patch, should prcjbably 

 be referred to the present species. The females of both species 

 are so variable in everj' character we have tested that it is quite 

 im|)ossible to say to which some exani))les should be referred. 



U))on comparing a .series of two males and as many females 

 of the European Golden-eye {G. (■luiujula) with a very large 

 number of American specimens, we are unable to detect any dif- 

 ference in coloration. The difference in size, however, is so great, 

 and, moreover, constant, as fully to justify their separation as 

 distinct races. 



The Golden-eye is a winter visitant to Illinois, its broediiig 

 range extending, "from the the 42d parallel northward"' 

 (HuEWEK), while its winter home is from about the same lat- 

 itude southward. 



"On Long Island, as Mr. Girautl states, the Golden-eye is 

 better known among the hunters as the 'Whistler,' from the 

 peculiar noise produced by its wings when flying. My others it 

 is also called the "Great-head," from its beautifully rich and 

 thickly crested head. On that island it is said to be a not very
