species, and one or two are cireumboreal. (See Annals of 
the New York Lyceum, Vol. vii.) 
I do not undertake here to enumerate nearly all the spe- 
cies of animals seen or collected, as Dr. Hayden has made 
a much fuller collection of them than I could do in so hasty 
a journey. 
Rattlesnakes (Crotalus confluentus?), some small Lizards 
(Sceloporus and Plestiodon), and the curious Horned Toad 
(Phrynosoma Douglassii) were all the reptiles observed = 
this dry season, though several others doubtless occur m 
spring. 
Young Curlews ( Numenius longirostris) and Field Plovers 
CActiturus Bartramius) were common on the plains. The 
Mountain Plover ( ZEgialitus montanus) appears on the driest 
plains among the villages of the Prairie-dog ( Cynomys Lu- 
dovicianus). I also shot some immature Buntings (Plectro- 
phanes), of which three species are found in Nebraska, and - 
confined to the Great Plains east of the Rocky Mountains. 
Near Sun River, which is a clear swift mountain stream, 
observed some middle-sized Squirrels ( Spermophilus Frank- 
linii?), but they were so exceedingly shy that I did not suc- 
ceed in getting any. Here the Rocky Mountains became 
fully visible, and mountain trees line the banks of the rive? 
I noticed here the first of Lewis’ Woodpecker (Melanerpes 
torquatus), which never leaves the neighborhood of the 
mountains. On the east side of the Missouri high range? 
are also visible, and the road now commences to ascend over 
rolling and often rocky hills, with pine woods on the — 
parts. August 13th two eggs of the Night-hawk were foun“ 
nearly hatched, laid as usual on the bare ground. t : 
. mouth of Prickly-pear Creek the Dusky Grouse (T — "d

Sharp-tail (Pediacetes phasianellus) , which we had found : 
along the Missouri River. ee
