Specimen No. 155 was found dead on the shore at head of lake; specimens Nos. 113 
and 155 with undeveloped sexual organs. 
24. Salvelinus malma (Walbaum). Dolly Varden Trout; Western Charr ; Bull Trout. 
Obtained in Alturas, Pend d’Oreille, and Wallowa lakes, where it is abundant and affords good 
sport for the angler. At Alturas Lake during July a great many were caught about the mouth of the 
inlet and many large examples were taken in Lake Pend d’Oreille. The charr is a voracious fish and 
preys largely upon other species of fishes. In the stomachs of some of those examined at Lake Pend 
d’Oreille were numerous specimens of Leuciscus balteatus, Ptychocheilus oregonensis, Myloclieilus eaurinus 
and Coitus. All of these except M. eaurinus were found in the stomach of one fish. Some specimens 
from this lake were infested about tho axils by a small crustacean of the genus Lernwopoda. 
Measurements of a number of specimens of charr are given in the following table:

tiFrom Alturas Lake, Idaho. c From Wallowa Lake, Oregon. 
b From Little White Salmon River, Washington. d From Lake Pend d’Oreille, Idaho. 
25. Salmo mykiss clarkii Richardson. American Cut-throat Trout. 
Numerous specimens obtained. Particularly abundant in Lake Washington, Siuslaw River, and the 
lakes near its mouth, Wallowa and Alturas lakes, Upper Klamath Lake, and in Des Chutes River. A 
comparison of many specimens indicates that it will be necessary to recognize more species or 
varieties of Salmo in the northwestern portion of the United States than have hitherto been admitted ; 
but it seems best to hold the matter open for additional data and consideration.
