INVESTIGATIONS IN THE COLUMBIA RIVER BASIN. 
195 
Numerous specimens (83) obtained in 1891 in the Snahe River at President Camp and in a 
small creek at the head of Jackson Lake, Wyoming,* have 11 or 12 anal rays, 12 being the number 
in most of the examples counted. In 1892, Dr. Eigenmann obtained specimens at Idaho Falls, 2 
of which have 12, 14 have 13, and 4 have 14 anal rays each. Putting these with the 13 col- 
lected by us, gives an average of 124 anal rays for that locality. This species was obtained 
also by Jordan A Gilbert in 1889 in Heart Lake and Witch Creek, in Yellowstone Park.t The 
specimens examined by them had 13 anal rays. In specimens from Idaho Falls the scales of 
lateral line range as follows: 52, 53, 53, 53, 55, 55, 57, 57, 58, 61: from Port Neuf River, 51, 51, 
51, 52, 53, 53, 55, 57. Head from 4 to 4 i in length, eye 3f to 3| in head. The maxillary scarcely 
reaches front of eye, and is 3 to 3^ times in head. 
19. Leuciscus lineatus (Girard). 
Tiyoma Hneata Girard, Proc. Acad. Nat. Sci. Phila. 1856, 206. Type locality: Not delinitely 
known, but jirobably somewhere in the Utah basin. 
Tiyoma atraria Girard, 1. c., 208. Type locality: “A spring in the Utah district, near the desert.’’ 
Tiyoma ohesa Girard, Proc. Acad. Nat. Sci. Phila. 18.56, 206. Pyiie locality: Salt Lake Valley. 
Tiyoma sqiiamaia Gill, Proc. Bost. Soc. Nat. Hist. 1861, 42. Type locality: Salt Lake Basin. 
(Sg'HaZiHs cr«o)Y'«s Jordan & Gilbert, Proc. U. S. Nat. Mus. 1880,400. Tyjie locality : Utah Lake; 
young specimens. 
r/(oi»i«?c«s Jordan & Gilbert, 1. c., 461. Type locality : Utah Lake; large specimens. 
Siboma atraria ionyiceps Cope. Zool. Wheeler Surv., v, 667, 1876. Type locality : Snake Creek, Nev. 
This sjiecies was obtained at the following places: Idaho Falls; Port Neuf River at 
Pocatello; Payette River at Payette. Others were seen at American Falls, in Snake River. 
Besides the localities given in the above synonymy, this llsh has been rejmrted from the fol- 
lowing additional points in the Snake River basin : Heart Lake and Witch Creek, in Yellow- 
stone Park (.Iordan & Gilbert, 1889); Snake River at President Camp; Jackson Lake and a 
small creek at upjier end of Jackson Lake, Wyoming, (Evermann &. Jenkins, 1891); Snake 
River at Idaho Falls, Idaho (Eigenmann). In the Columbia basin it seems to be entirely 
confined to the Snake River, and in that stream its occurrence below the falls is exce]itional. 
It is an excessively abundant lish in the Great Salt Lake basin, particularly in Utah Lake. 
In the canal at Idaho Falls we easily caught this and the preceding species by placing dough 
inside a small dip net and allowing it to rest a short time on the bottom ; great numbers of the 
two species, particularly of L. hydrophlox, would soon begin feeding on the dough, when they 
could be easily secured by lifting the net. In all recent papers this species has been listed 
under the name Leuciscus atrarius, but it seems quite certain that Tiyoma Jineuta Girard is the 
same fish; and this, being the older name, must take the place of atrarius. 
20. Leuciscu.s aliciae Jouy 
Tiyoma yracilis Girard, Proc. Acad. Nat. Sci. Phila. 1856, 206; not Cyprinus {Leuciscus) yracUis 
Richardson. 
SquaJius copei Jordan A Gilbert, Proc. U. S. Nat. Mus. 1880, 461; not Leuciscus copei Giinther. 
Leuciscus aliciw Joay, Proc. li. S. Nat. Mus. 1881, 10. Type locality: Utah Lake. 
This species was found ver5^ abundant in Little Wood River at Shoslione, where 86 sjieci- 
mens were obtained. Slight differences are found on comparison of these specimens with 
others from the Sevier River, Utah, but these differences are not likely to prove constant and 
are not more extensive tlian are frequently found on comparing specimens from adjacent 
tributaries of the same sti’eam. The eye is a trifle larger, the caudal peduncle rather more 
slender, the pectoral and ventral tins seem to average a little shorter, and the dorsal may be 
a little more anterior in position. 
This species has been previously known only from Sevier River, Beaver River, and Provo 
River in Utah. Its occurrence in the valley of the Upper Snake River is one more evidence of 
the identity of the two faunas. At least 8 of the species of our collection from the Upper 
Shake River are also found in the Great Salt Lake Basin of Utah. They are Catosfomus ardcus, 
Lihinichthys dulcis, Ayosia nubila carrinytonii, Leuciscus hydrophlox, Leuciscus alicue, Leuciscus 
lineatus, Coreyonus wiUiamsoni, aud Cottus punctulutus. 
The following is a detailed description of our specimens from Little Wood River: Head, 
4 (3f to 44); depth, 4 to 44; eye, 3f to 4; snout, 3f to 4. D. 8; A. 8, in .52 specimens, 9 in 34. 
Scales, 18-79 to 83-13. Body elongate, moderately compressed; head short and heavy,
