River, Nevada ; perhaps identical with L. eyreylm, but the type specimen 

 is much deeper than any cyrvyiux we have seen. (Named for Alexander 

 vou Humboldt.)

374. LEUCISCUS EGREOIUS (Girard). 



Head 3f to 4 J ; depth 3 to 4J ; eye 4J. 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 rather 

 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 Winnemucca, sent by Frank Germain. These have been compared 

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

 This species may ultimately stand as Leuciscus hiimboldti. (egregiua, sur- 

 prising.) 



Tigoma egregia, GiRAnD, Pac. R. R. Surv., x, 291, 1858, locality unknown, but probably Great 

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

Squalius ardesiacus, JORDAN & GILBERT, Synopsis, 235,1883. 



Squalius egregius, JORDAN & GILBERT, Synopsis, 236, 1883. 



* Gila ardesiaca, COPE. Head 3%; depth 4 ; eye 4. D.8;A.8. Scales 17-63-8. Teeth 2, 5-4, 2. 

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

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

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



i&jualius galtife, COPE. Head 4; depth 4% ; eye 3 in head. D. 8; A. (probably) 8. Scales 

 12-GO-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. Interorbital region gently and regularly convex, as 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, except a broad band of crimson from the gill 

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



IPJioxitms clevelandi, EIOENMANN & EIGENMANN, Head 4%; depth 4%; eye 4%. D. 9; A. 9 or 10. 

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

 slightly beyond ; eye 1% in interorbital 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 aud dark of back; fins mostly dusky. Length 4 

 inches. Jilt ... Springs, Napa County, California. One of the types received from Dr. HfpB* 

 mann seems to agree fully with L. egregius. 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.
