RANGE OF THE Geococcyx CALIFORNIANUS.—I am advised, by 
letter from my friend, Dr. A. Woodhull, of the army, of the occur- 
rence of this species on the Arkansas river near Ft. Lyon, Colorado, 
a fact which carries the known range of the species considerably 
eastward. Excepting Mr. C. E. Aiken’s recent quotation from the 
mountains of Colorado (Proc. Bost. Soc., xv, 206), the U.S. record 
has hitherto been only from Texas, New Mexico, Arizona and Cal- 
ifornia to the Sacramento valley. The bird appears to be rare in 
the locality, where my correspondent says only two or three were 
seen in the course of over two years. He says it is known as the 
“war bird” or ‘‘ medicine bird,” because prized by the Indians for 
its plumage, which is used to ornament their regalia of ceremony.

Tue CARIBOU on Lake Superior.— During a recent visit (May 
1873) to Isle Royale, Michigan (Lake Superior), interesting evi- 
dence of the former presence of the Caribou (Rangifer Caribou 
Aud. and Bach.), long extinct there, was brought to my observa- 
tion. Ihave now in my possession two relics—the greater parts 
of the horns of this animal — which were picked up at different ` 
points on the island. The antlers are much decayed, one being 
a mere shell, and, beside, they had been gnawed by rodents. 
Such specimens, often of a great size, are frequently discovered 
of late at this isolated place.—Henry Gitiman, Detroit, Michigan. 
CHIMNEY SWALLOW; CHANGE IN PLACE OF Nestinc.— About 
June 15, 1871, a pair of chimney swallows (Chetura pelasgia) 
commenced building a nest in the barn in close proximity to the 
nests of the common barn swallow (Hirundo horreorum). The 
nest was finished by the 4th of July, and four eggs were laid. In 
1872 there were two nests built in the barn, and this year two 
more were built, one of which I took down on July 8th and sent, 
with the four eggs which it contained, to the Peabody Academy of 
Science. The nest that I removed was replaced by a new one 
about the 20th of July. As this is a remarkable variation in the 
habits of the chimney swift, I send you this note with the nest. 
I shall watch for the appearance of the birds in the barn next 
year with interest. As they have now built in the barn for three
