989. CYPRINODON BAILEYI (Gilbert). 



To this species are referred 11 immature specimens from Pahranagat 

 Valley, Nevada, none of them showing trace of ventral fins. They are 

 olivaceous above, bright silvery on the lower half of sides and below, 

 and have 2 lengthwise series of coarse black spots, 1 along middle line of 

 body, the other on a level with the lower edge of caudal peduncle. The 

 anal fin is larger than in typical macularius, the 11 specimens having each 

 13 rays instead of 10 or 11, as constantly in the latter. Pahranagat Val- 

 ley, Nevada. (Gilbert.) Perhaps a variety of C. macularius. (Named for 

 Vernon Bailey, its discoverer.)

 Valley, Nevada. (Type, No. 46110. Coll. Merriam & Bailey.) 



990. CYPRINODON ELEGANS, Baird & Girard. 



Head 3|; depth 2| to 3. D. 11 ; A. 10; scales 26-12. Body more elongate 

 than in any of the preceding ; the upper putline of the head less depressed, 

 so that the profile is continuous ; fins low, the dorsal quite small ; its rays 

 scarcely extending to the beginning of the caudal peduncle. Head large. 

 Bluish black, sides somewhat variegated with'darker, the males somewhat 

 spotted ; dorsal fin speckled at base ; edge of caudal fin black in the male ; 

 a black patch on last rays of dorsal in the female. Length 2-& inches. 

 Tributaries of the Rio Grande; specimens apparently belonging to this . 

 species from Rio de los Conchos, at Chihuahua. This species may prove 

 inseparable from C. bovinus. (elegans, elegant.)

991. CYPRINODON MARINE, Steindachner. 



Head 3 ; depth nearly 4 ; eye 3 in head ; snout 3. D. 9 ; A. 10 ; V. 7 ; 

 P. 16 ; scales 26-9. Body rather elongate ; snout blunt ; teeth tricuspid, 

 in 1 row ; top of head broad ; dorsal and anal very high in male, the 

 height of dorsal 2 times its base, the last rays reaching beyond base of 

 caudal ; insertion of anal under middle of base of dorsal ; insertion of 

 dorsal nearer that of caudal than tip of snout by half length of head ; 

 ventral as long as head, equal to pectoral; caudal weakly concave; scales 

 largest about shoulder and nape. Back grayish ; sides silver white ; male 

 with anterior margin of dorsal dusky; last 3 or 4 rays of dorsal and anal 

 banded, for their whole length, with light and dark in alternation, the 

 others more faintly marked and only toward their base ; 2 or 3 dark" bands

 on the Caribbean coast of Colombia, near the mouth of Rio Magdalena.
