Subgenus FULIGULA Stephens. 



38. Aythya marila nearctica (Stejn.). AMERICAN SCAUP DUCK. 



Bare migrant, appears to be more common in the Wabash Valley, where it 

 has been noted on several occasions, in Vigo County, by Professors O. P. Jenkins r 

 B. W. Evermann and Dr. J. T. Scovill. It has also been noted by Mr. H. W. 

 McBride, in Dekalb County ; Mr. C. A. Stockbridge, in Allen ; Prof. Evermann, in 

 Monroe ; Dr. Raymond, in Franklin. 



*39. Aythya affinis (Eyt.). LESSER SCAUP DUCK. 



Common migrant and rare summer resident. Breeds. Mr. Ruthven Deane 

 informs me that he has reliable authority for saying a pair bred at English Lake 

 in 1886, where they were seen with their young. They were supposed to be " crip- 

 ples." He also informs me of a flock of thirteen seen there June 5, 1888. Mr. J, 

 G. Parker says *' they are the most common of all the ducks" during migrations, 

 and afford the main duck shooting in the vicinity of Chicago. 



40. Aythya collaris (Donov.). RING-NECKED DUCK. 



Migrant ; generally recognized as rare, but in the northern part of the State 

 tolerably common. Occasionally found in winter in the southern part of the 

 State. 



GENUS GLAUCIONETTA STEJNEGER. 



41. Glaucionetta clangula americana (Bonap.). AMERICAN GOLDEN-EYE. 

 Migrant and winter resident. Said to be common about Lake Michigan. 



(Parker.) 



42. Glaucionetta islandica (Gmel.). BARROW'S GOLDEN-EYE. 



Rare visitor in winter and spring. There are, so far as I know, but two records 

 of the occurrence of this species in the State. Dr. F. Stein took it on the lower 

 Wabaeh River, Gibson County, December, 1874, ("Bull. Nuttall Orn. Club," July, 

 1876, p. 41,) and Prof. B. W. Evermann near Camden, Carroll County, March ]9 r 

 1885, (" The Auk," October, 1888, p. 347.) " Winter resident on Lake Michigan," 

 (Brayton). 



GENUS CHARITONETTA STEJNEGER. 



43. Charitonetta albeola (Linn.). BUFFLE-HEAD; BUTTER DUCK; BUTTER BALL. 

 Common migrant and winter resident. Some winters they are present through- 

 out the entire State; others, when the northern streams and lakes are ice-bound, 

 they are only found along the southern border. This is, however, true of most of 

 the ducks that spend the winter in the State. 



GENUS CLANGULA LEACH. 



44. Clangula hyemalis <Linn.). OLD SQUAW. 



Winter resident and migrant, not generally common throughout the State, but 

 found occasionally on the larger watercourses. Mr. J. W. Byrkit informs me that 

 they are very " abundant in the lake (Michigan) off Michigan City and are caught 

 in abundance in the gillnets in twenty to thirty fathoms of water." It has been re- 

 ported from the mouth of the Great Miami River (Dearborn* County), Feb. 24, 

 1880, where one was taken by Mr. T. J. Baum. (Journ. Cin. Soc. Nat. Hist., Dec, 

 1S81, p. 341); from the Whitewater River (Dury), and a specimen in my collec-
