standing in plain view. This, however, was a rare occurrence. Ar- 

 rives the last of October or first of November, and departs the first 

 of April. 



276. B. islandiea Bd. BARROW'S GOLDEN-EYE DUCK. A winter 

 resident upon Lake Michigan, and found irregularly throughout the 

 state at that season. A specimen was obtained at Mt. Carmel, on the 

 Wabash River, in December, 1874, by Professor F. Stein, and I have 

 observed it at Chicago. Dr. Hoy writes that a specimen was shot at 

 Racine during the winter of 1860. They are probably not uncommon 

 upon the Lake in winter, but owing to the great difficulty experienced 

 in collecting ducks on perfectly open water at this season, a definite 

 knowledge of the numbers in which this and several other aquatic 

 species visit us during winter has not been obtained. 



277. B. albeola Bd. BUFFLE-HEAD DUCK. The most abundant 

 species of the genus. Frequents the rivers and other inland waters 

 in greatest abundance. Immense numbers are sent to the Chicago mar- 

 ket each season. Although abundant with the preceding upon Lake 

 Michigan, it is still more numerous on the inland waters. Winter 

 resident. Arrives the last of October and sometimes remains until 

 the first of May. 



Genus Harolda Leach. 



278. H. glacialis {Linn.}. OLD-WIFE DUCK. An exceedingly 

 abundant winter resident upon Lake Michigan and sparingly dis- 

 persed throughout the state during that season. It was obtained by 

 Professor Stein at Mt. Carmel, in December, 1874. A few stragglers 

 make their appearance the last of October, but the main body do not 

 arrive until about the first of December. The last of March or first 

 of April nearly all depart for the north, but a few are found until the 

 last of the mouth. Just before they migrate they unite in large flocks 

 and make a great gabbling and noise. At all times while here they 

 are very shy and difficult to obtain. 



Genus Histrionicus Lesson. 



279. H. torquatus (Linn.). HARLEQUIN DUCK. Rather rare 

 winter resident upon Lake Michigan. Dr. Hoy has secured several 

 specimens at Racine. 



Genus Somateria Leach. 



280. S. mollissima Leach. - EIDER DUCK. Not a very rare winter 

 resident upon Lake Michigan and probably occurs in suitable places 

 throughout the state. In my collection is an immature specimen, ob- 

 tained near Chicago in December, 1874, and Dr. H. B. Bannister has 

 several times noted them at Evanston. Dr. Hoy informs me that a 

 specimen was shot at Racine in January, 1875.
