284 SCIENCE SKETCHES. 
ally taken a trout which the Indians call No-Shee,! 
or Nissuee, and which must resemble the original 
stock of the San Joaquin even more closely than 
the Kern trout does. It has the small scales of 
the Kern River fish, but the red cut-throat mark is 
gone, and the spots are few and sparse. It is a 
large trout, and is but rarely taken, the specimens 
now known being from the McCloud. 
The common trout of the Upper Sacramento 
may be descended from this; but its scales are 
larger, its body deeper, the red band on the sides 
more distinct, and there is at least a trace of the 
cut-throat mark, showing where its tribe came 
from. This trout is the one distributed from 
the hatchery at Baird as the California Rainbow 
Trout,? and planted, often ineffectively, in many 
Eastern rivers, — ineffectively, I say, because of its 
bad habit of dropping down with the current and 
losing itself in unwholesome waters on its way to 
the sea. The true Rainbow Trout is, however, 
somewhat different. That name belongs to the 
common trout of the Coast Range; smaller, with 
large scales, white throat, and varying much with 
streams and food. The large scales seem to mark 
a change on which we make, provisionally, a divi- 
sion of species. The little trout of the Coast 
Range? is likewise an offshoot of the Steel-head. 
1 The No-Shee Trout is Salmo gairdneri stonei Jordan, named 
for its discoverer Livingston Stone, the veteran fish-culturist of 
the U. S. Hatchery at Baird, California. 
2 The Rainbow Trout of the Upper Sacramento is Salmo gaird- 
neri shasta Jordan. 
3 The Trout of the Coast Range is Sa/mo iridexs Gibbons; the 
type locality of the species being San Leandro Creek, in Alameda 
County.
