6. Podilymbus podiceps (Linn). [735.] Pied-billed Grebe ; HellDiver ; Dabchick. 
Winters wherever there is open water, from Illinois southward, and 
breeds from southern Indiana, Illinois, Missouri, and eastern Kansas 
northward. The records for 1884 are so irregular that it can only be 
said that during the last of April and first of May the Dabchick was 
migrating on both sides of the forty-third parallel, and appeared May 
6 at Portage la Prairie, Manitoba. In the fall of 1884 it was first seen 
at Emporia, Kans., September 20 and was common the same day. 
The records for 1885 are scarcely more regular than those for 1884. 
Its arrival was noted at Laporte City, Iowa, April1; Lanesboro, Minn., 
April 3; Saint Louis, Mo., April 6; Paris, Ill., April 19; Heron Lake, 
Minn., April 9, and Shell River, Manitoba, May 3. In the fall of 1885 
the first came to Emporia, Kans., September 16, and to Shawnee- 
town, Ill., October 3. The last left Lanesboro, Minn., November 9, and 
Saint Louis, Mo., October 27. Mr. Lloyd states that it is tolerably 
common in winter in Tom Green and Concho counties, Texas (The Auk, 
Vol. IV, 1887, p. 184). 
7. Urinator imber (Gunn.). [736.] Loon. 
Breeds from northern Illinois and Minnesota northward. Occurs in 
winter at suitable localities over most of the Mississippi Valley, even 
as far south as San Angelo, Tex. (Lloyd), Corpus Christi bay (Sen- 
-nett), and Waverly, Miss. (Young). During the first eleven days of 
April in 1884 it was recorded at various places from latitude 39° to 
latitude 45° 25’, and May 1 it reached Oak Point, Manitoba. 
In the spring of 1885 two sets of notes were contributed. The first 
was as follows: Laporte City, Iowa (lat. 42° 18’), March 31; New Cassel 
Wis. (lat. 43° 40’), April 4; Excelsior, Minn. (lat. 449 55’), April 5; 
Emmetsburg, Iowa (lat. 43° 8’), and Saint Louis, Mo. (lat. 38° 40), 
April 6; Heron Lake, Minn. (lat. 43° 48’), April 8; Lanesboro, Minn. 
(lat. 43° 43’), April 9. The second set was: Luck, Wis. (lat. 45° 35/), 
April 20; Des Moines, Iowa (lat. 41° 36’), Ferry, Iowa (lat. 419 14’), and 
Lake Mills, Wis. (lat. 43° 6’), April 21, and Shell River, Manitoba, May 
4. The last left Saint Louis, Mo., April 11, and Ferry, Iowa, April 29. 
In the fall of 1885 the last left Heron Lake, Minn., November 7. 
9. Urinator arcticus (Linn.). [738.] Black-throated Diver.

Lakes. 
11. Urinator lumme (Gunn.). [740.] Ied-throated Diver. 
A northern species; breeding about the larger lakes in Manitoba, and 
thence northward; dispersed in winter irregularly over the northern 
half of the Mississippi Valley. 
21. Synthliboramphus antiquus (Gmel.). [753,759.] Ancient Murrelet; Black- 
throated Guillemot. 
Inhabits the islands and shores of the North Pacific; accidental once 
on Lake Koshkonong, Wis. (Sennett, Auk, Vol. I, 1884, p. 98).
