BULLETIN OF THE UNITED STATES FISH COMMISSION. 
specimens of the present collection agree most nearly with the Spokane group, as may he seen from 
the following table. The barbel is, however, oftener present in these Idaho specimens. 
The following table gives comparative measurements of 19 specimens from the three localities:

11 . Agosia Umatilla Gilbert & Evermann. 
The only species of Agosia found at the Eedfish lakes agrees well with the tyj>e and description 
of A. nmatilla. Our collection contains 28 specimens from Pettit Lake Outlet and 19 from Alturas 
Lake, all collected in .Inly and August. It does not appear to be at all common and is not among the 
collections made at the Payette lakes. 
12 . Agosia falcata Eigenmann. 
The collection made in Snake River near Weiser, Idaho, September 22, 1894, contains 66 examples 
of this species. It is now known from the following localities : Boise River at Caldwell, Idaho (type 
locality); Payette and Snake rivers at Payette; Mill Creek near Walla Walla, and Columbia River 
at Umatilla and Pasco. 
13 . Coregonus williamsoni Girard. Koclcy Mountain TVhiteJish; “Mountain Herring.” 
This whitefish seems to be a common species in all suitable Avaters in Idaho. It was found by us 
in Snake River at UpiAer and Lower Salmon Falls, Glenn Ferry, and Weiser; Little Weiser River at 
Indian Valley; Big Payette Lake and Payette River; Redfish, Pettit, and Alturas lakes; Alturas and 
Pettit lake outlets, and Salmon RiAmr. The following information Avas given by different xmrsons with 
whom Ave talked concerning this fish : 
Charles Harvey, Lower Salmon Falls : “Common at this place ; attains a weight of three-fourths 
of a pound, though half a j)ound is the usual Aveight ; it is a very fat fish, and readily takes a hook 
baited Avith a grasshopper or grub; it proljably spawns late in September.” 
John W. Smith, Council Valley : “There are millions of mountain herring in Payette Lake; they 
spawn in October, going far up the inlet aboA'e Avhere the redfish spaAvn. A few years ago we caught 
2,200 at one haul of a 75 or 80 foot seine. These fish Aveigh about half a ijound undressed, or one-third 
of a pound dressed.” 
F. C. Parks, Sawtooth : “The mountain herring are common in the Redfish lakes and connecting 
streams. They usually weigh about one-fourth of a pound, though I have caught them in Salmon 
River weighing 2 pounds. They take the hook readily in the spring and early summer.” 
Thomas McCall, Lardo : “The whitefish are very abundant in Big Payette Lake. Their spawning 
time is in October, Avheu they run up the inlet in astonishing numbers. In October of the iiresent 
year ( 1895) they were more abundant than usual. Ten wagonloads were caught AA^ith seines and pitch- 
forks, and as many more might have been taken Avithout causing any appreciable decrease. They 
began spawning almut the middle of October and the run lasted about two weeks, Avhen the fish 
returned to the lake. They would average about three-quarters of a pound undressed. Many of 
those caught we found ready sale for in Warren and Boise at 10 to 15 cents a pound.”
