SYSTEMATIC REPORT. 
1. Hichmophorus occidentalis (Lawr.). [729.] Western Grebe. ; 
An inhabitant of western North America, coming eastward to Mani- 
toba. Twenty years ago Donald Gunn discovered this Grebe breeding 
abundantly at Shoal lake and Lake Manitowaba, Manitoba (Smithson- 
ian Report for 1867, pp. 429-430). More recently Prof. John Macoun, 
botanist to the Geological and Natural History Survey of Canada, found 
it breeding “in thousands” on Waterhen river; and still more recently 
Mr. Ernest E. T. Seton (now E. E. Thompson) has recorded specimens 
from Long lake, Manitoba (The Auk, Vol. II, 1885, p. 314). 
2. Colymbus holbcellii (Reith.). [731.] Holbell’s Grebe; American Red-necked 
Grebe. 
A northern species, coming south in winter irregularly to the northern 
half of the Mississippi Valley; has been taken as a rare visitant at’ 
Alda, Nebr. Said to breed in northern Manitoba. 
3. Colymbus auritus Linn. [732.] Horned Grebe. 
Winters over most of the Mississippi Valley and breeds from northern 
Illinois northward; reported by various observers in Missouri, Ne- 
braska, and Wisconsin. In 1885 it arrived at Lake City, Minn., April 
23. 
4. Colymbus nigricollis californicus (Heerm.). [733a.] American Eared Grebe, 
Occurs throughout the western row of States in the district; breeds 
from Texas northward, and winters from Texas southward; was noted 
by observers at Saint Louis, Mo., Manhattan, Kans., Ellis, Kans., and 
Vermillion, Dak. In the spring of 1885 it was first reported from Em- 
poria, Kans., April 14, and again April 30. At Saint Louis, Mo., the 
first, a male, came April 24. In the fall of 1885 it was seen at Emporia 
September 8 and at Saint Louis September 22. It remained at Saint 
Louis until October 7. - 
5. Colymbus dominicus Linn. [734.] St. Domingo Grebe. 
This is a tropical species, coming north to the valley of the lower 
Rio Grande in Texas. Near Fort Brown it is a “ rather common resi- 
dent” (Merrill, Proc. U. 8S. N. Mus., 1878, p. 172). It occurs at least as 
far up the river as Lomita ranch, above Hidalgo (Sennett, Bull. U. 8. 
Geol. and Geog. Sur. Ter., Vol. V, No. 3, 1879, p. 440).
