River, Nevada ; perhaps identical with L. lyrcijiiifi, Imt thu type specimen 

 is much deeper than any c(irci/iii>: we have seen. (Named for Alexander 

 von Humboldt.)

■574. LEUf ISCUS EGREGIUS (Girard). 



Head 3f to 4J ; depth 3| to 4J-; eye 4ir. D. 8; A.9; scales 12 or 13-52 to 56-6 

 to 8. Teeth 2, 4-5, 2, without grinding surface. Eye large. Body ratlier 

 robust, compressed. Mouth oblique, the jaws equal, the maxillary about 

 reaching front of eye. Fins all high, the anal shorter than in L. hydro- 

 phlox. Back blackish, with a broad blackish vertebral streak ; usually 

 two parallel dark bands along anterior third of sides, separated by alight 

 streak one-half width of pupil. In life this light interspace is flushed 

 with red. Posteriorly the two dark bands merge into a single median one 

 on caudal peduncle and the lower is sometimes wanting ; belly golden, with 

 some red in males. A broad red streak nearly as wide as orbit bordering 

 the dark lateral streak and extending to opposite front of anal. Top of 

 head, snout, chin, and an irregular band behind eye blackish ; axil scar- 

 let; a golden crescent on cheek; fins unmarked. Length 3^ inches. 

 Nevada to northern California, known from the Humboldt and Truckee 

 basins and from Napa Valley ; extremely common in Lake Tahoe and 

 Truckee River. Here described from specimens from the Humboldt River 

 at Winuemucca, sent by Frank Germain. These have been compared 

 with the type of L. clevelandi, which seems to be identical with them. 

 This species may ultimately stand as Leuciscns humboldti. (egregius, sur- 

 prising.) 



Tigoma egregia, Girarb, Pac. R. R. Surv., x. 291, 1858, locality unknown, but probaljly Great 

 Basin of Nevada, the drainage of Lake Lahontan. (Coll. Kreuzfeld.) 



Gila ardesiaca* Cope, Zoiil. Wheeler Surv., v, Cfid, pi. xxx, figs. 1, lo, 1875, (1876), locality un- 

 known, probably Nevada. (Type, No. Ui'Mi. Coll. Yarniw & Hensliaw.) 



Sipialiiis gaUia;,j- Cope, Proc. Ac. Nat. Sci. Pliila., 1883, 148, Pyramid Lake, Nevada. 



Phoximis cleL-eJaHdi,X C. II. and R. S. Eigenmaxn, West American Scientist, 1889, 149, iEtna

SquaUus ardesiaciis, Jordan & Gilbert, Synopsis, 235,1883. 



Squalnis egregius, Jordan & Gilbert, Synopsis, 236, 1883. 



* Gila ardciiaca, Cope. Head 3%; depth 4J ; eye 4. D.8;A.8. Scales 17-G3-8. Teeth 2, 5-4, 2. 

 Body rather stout, compressed ; head heavy, muzzle short ; mouth short, very oblique, the jaws 

 about equal, the miixillary reaching past front of the large eye. Pectoral fin long, nearly 

 reaching veutrals. Olivaceous above, a narrow plumbeous lateral band concurrent with the back. 



tS/Ko/JHs gallia:, Cope. Heiiil 4; depth i}-^; eye 3 in head. P. 8; A. (probably) 8. Scales 

 12-00-5. Teeth 1,4-5,1, without grinding surface. Dorsal inserted a little behind front of 

 ventrals ; muzzle short; mouth oblique, without prominent chin, the end of the maxillary 

 reaching a little beyond front of orbit. Intcrorbital region gently and regularly convex, iis wide 

 as eye. Olive above, as far as a plumbeous band, which extends from the operculum to base of 

 caudal; below this line, sides and belly silvery, excepta broad band of crimson from the gill 

 opening to front of anal ; side of head with a dusky band. Pyramid Lake, Nevada; abundant. 



iPhoxiuHS clevelandi, Eigenmann & Eioenmann, Head 4}^; depth 4VC; eye 4]4- T>. 9; A. 9 or 10. 

 Scales 10-59-6. Teeth 2, 4-5, 2. Mouth oblique ; jaws equal ; maxillary reaching front of eye or 

 slightly beyond ; eye 1)^ in intcrorbital space; pectorals reaching ventrals in males, shorter in 

 females. Dark brown above, bordered by a darker stripe ; a black band from tip of snout to 

 base of caudal, a pale band between this and dark of li.ack ; fins mostly dusky. Length 4 

 inches. JEt .. Springe, Napa Cminty, California. One of the ty])es received from Dr. Eigen- 

 mann seems to agree fully with /.. egregim. In general, however, the fauna of the Sacramento 

 Valley has little "in common with that of the Lake Lahontan drainage to which the Humboltd 

 and Trucrikee vers belong.
