I wish to call attention to a circumstance which Daleau does 
not mention. The finely chipped "perfected Chelleen" implement, 
with white patine on one side and yellow patine on the other face, 
would indicate that its owner pursued his game on the surface of 
the yellow tertiary bed of sand and that the implement assumed 
the yellow tint on its under side from the yellow sand which had 
become fine enough to hold it in place during the time that the 
earliest quaternary deposit was forming. This seems to justify 
the idea that the implement in question was made and deposited 
during the Tertiary, before the Quarternary sands were deposited.

KING EIDERS AT ^riLWAUKEE. A CORRECTION. 
^ly attention has recently twice been called to a misleading 
statement on p. 113, Vol. IV of this Bulletin in my Notes Of 
(should read On) the Herring Gull and Caspian Tern, where, 
writing of the ducks coming into the river between the factory 
lined docks in winter, I mention them as being "principally Old 
Squaws, Lesser Scaup and King Eiders." This is an error, and 
as the sentence stands American Golden Eyes should be substi- 
tuted for King Eiders. I have an imperfect recollection of hav- 
ing left the third place open for reference to some misplaced 
notes on the comparative numbers of the ducks and intending to 
record the king eider as occasional. 
I know of only three specimens of king eider actually and 
certainly taken at this point. Two of these are recorded by 
Hollister in The Birds of Wisconsin, Wis. Xat. Hist. Society, 
Bull. Nos. I, 2 and 3 of A'ol. HI, i. e., a female taken Dec. 25, 
1899, and a male Jan. i, 1900, both in the Copeland-Russel col- 
lection in this city ; and a female taken within the harbor Xov. 28, 
1903, and now in the Public ^Museum. The museum also pos- 
sesses two other specimens, an adult and an immature male 
received by gift from the Wis. Xat. Hist. Socy. about twenty-five 
years ago, at the time of the founding of the museum. The only
