Agosia nubila carringtoni (Cope). 
The examples of Agosia taken in the Malheur, Oregon Lake, and Upper Sacramento basins are all 
provisionally included under the above name. In the recognition of this form, and also of A. klama- 
thensis, the size of the scales seems to be the only distinctive character that has been observed. The 
specimens from the Malheur basin have 60 to 79 scales in the lateral line, thus agreeing with examples 
of A. nubila carringtoni from the upper Snake River. Those from the Oregon Lake system have 66 
to 81 scales, resembling the Klamath form, A. klamathensis, and differing from a recently described 
Lahontan species which has 56 to 77 scales.b> Examples from Goose Lake and its tributaries have 61 
to 74 scales in the lateral series and are apparently indistinguishable from those of the upper Snake 
River and Malheur basins; but the matter is not simplified when specimens from other parts of the 
Sacramento basin are found to have as few as 50 scales, thus resembling A. nubila nubila of the Colum- 
bia River. 
The Agosia from the Klamath basin is said to have the barbel constantly present. In specimens 
from the Oregon Lake basin it is usually present, although it may be absent in many cases. It will 
be noted in the following table that specimens from Silver Creek (Malheur basin) have barbels, while 
those from Warm Springs have none. 
Specimens were taken in the following localities: Cottonwood Creek, Drew Creek, Muddy Creek, 
and Goose Lake, Oregon; Joseph Creek, Burney Creek, and Rush Creek, California; Warner Creek, 
Honey Creek, Chewaucan River near Paisley and at mouth, Silver Creek, in Lake County, Bridge Creek, 
Buck Creek, Silver Creek, in Harney County, and Warm Springs.
