BULLETIN OF THE UNITED STATES FISH COMMISSION. 
lu most of the streams seined by Mr. Woolman and the writer in western Montana, 
Idaho, and Washington the yoniig, parr-marked whitelish Avas taken. These young 
fish were obtained in several quiet streams, almost sluggish, so weak was the current. 
In Siiokane Eiver at the city of Spokane large numbers of adult whitefish could be 
seen from the city bridges. They would lie or swim close to the bottom, keeping in the 
shade of the bridges, and would bite at grasshoppers. The artihcial fly seemed to have 
no attraction for the tish. 
This whitefish grows to a length of 15 inches, has excellent flesh, and is by many 
confiised with the grayling, ThymaUns. The Columbia Eiver chub, Mylocheilus cau~ 
riiiiis is often called ‘‘whitefish.” The type of Coregonus wilUamsoni was obtained in 
the Des Chutes Eiver, Oregon, and described by Dr. Girard in the Proceedings of the 
Philadelphia Academy of Sciences in 1850, and again in 1858 in the Pacific Eailroad 
Survey reports. Later recorded localities are: Willamette and Columbia rivers, 
Oregon ; the Columbia and its tributaries in Washington ; Lake Tahoe, Trout Creek and 
Truckee Eiver, California ; lakes and streams of Idaho, Montaua, Wyoming, Colorado, 
and Utah. The species ranges north into British America and eastward to the moun- 
tain tributaries of the Upper Missouri, several of the localities given by Prof. Evermaun 
being east of the Continental Divide. 
ANNOTATED LIST OF REPTILES AND BATRACHIANS. 
[By .John Denburgh, student, Lelaud Stanford Jnnior University.] 
But few reptiles and batrachians were observed by members of the exifedition, 
partly because no special effort Avas made to collect them, and partly because they 
were not abundant in most of the region traversed. Both lizards and snakes seemed 
to be rare on the barren lava plains of the Snake Eiver, where Sceloponis gyaciosus, 
Phrytiosoma douglassi, and Fhrynosoma platyrhiims Avere the only species seen. The 
case was different in the bottom lauds of the Snake Eiver below Shoshone Falls, Idaho. 
Here lizards were extremely abundant and in considerable variety. Species of Uta, 
Crotaphytus, and Gnemulopihorus Avere as numerously represented as on the hot deserts 
of southern California. Two species of Sceloporus were also seen, but of these no 
specimens Avere secured. The richness of reptilian life on the sandy floor of the valley 
contrasted strongly Avith the reverse condition on the lava i)lains immediately bordering 
the valley and but a few hundred feet above it. 
1. Crotaphytus wislizenii Baird & Girard. Two fall-grown specimen.s collected in the bottom lands 
of the Snake Biver near Bliss, Idaho, August 8. AA'ith the exception of Cnemidoyhorus tiyris, 
this was the most abnndaut s|)ecies observed. 
2 Uta stansburiana Baird & Girard. A single badly mutilated specimen from Snake Eiver bottoms, 
near Bliss, taken August 8. The species rvas not rare, and was usually observed on rocks. 
3. Sceloporus graciosus Baird & Girard. Six si)ecimeus from near Poc.'itello, Idaho, August 3; two 
specimens from near Idaho Falls, Idaho, August 5; three specimens from near Umatilla, Oreg., 
August 11. This species was always observed on the ground, and was seen both among the 
coarser basalt and on the finer sands and gravels. 
4. Phrynosoma douglassii (Bell). This pygmy horned toad seemed by no means abundant. The 
largest specimen, 68 mm. long, was taken at Pocatello, Idaho, August 4. Two other specimens 
were captured: one on the Clearwater River, 7 miles above Lewiston, August 15; the other 
at North A'akima, AA'ash., August 23.
