interorbital space. Origin of dorsal in female midway between tip of 

 caudal and front margin of orbit, opposite seventh or eighth anal ray ; 

 origin of dorsal in male in middle of the total length ; anal process of 

 male shorter than head ; pectoral fins not quite reaching as far as ven- 

 trals; length of base of anal fin of the female i its distance from caudal. 

 Upper half of body and dorsal fin with series of black dots. Rivers of 

 Cuba; very common ; our specimens from Rio Almendares. (punctatus, 

 speckled.)

Head 4; depth 3|; eye 3 in head. B. 6 ; D. 9; A. 11; V. 6; scales 30; 

 vertebrae 13 + 19. Lower jaw projecting beyond the upper. Origin of 

 dorsal in female midway between extremity of caudal and center of eye, 

 opposite middle of anal; in male origin of dorsal in the middle of total 

 length; anal process of male longer than head; pectoral and ventral fins 

 short ; free portion of tail rather deep. Body with scattered black dots ; 

 an oblique blackish band below the eye; dorsal and caudal fins with 

 transverse series of black dots. Streams of Cuba. (Poey.) (puncticu- 

 latus, dotted.)

 999. GAMBUSIA INFANS, Woolraan. 



Head 4|; depth 4i. D. 8; A. 8; scales 26. Body slender. First rays 

 of dorsal midway between snout and end of caudal, or midway between 

 the posterior margin of opercle and end of scales ; insertion of anal 

 almost directly beneath first rays of dorsal ; base of dorsal very short, 

 slightly more than length of orbit; diameter of orbit a little greater 

 than length of snout, about 2 in head; modified anal of males about 1^ 

 times length of head, or about equal to the distance from insertion of 

 dorsal to end of scales; ventral fin short, not reaching vent. Back 

 light olive green; but few scales with dark edges or other marking 

 except a very narrow hair line along the middle of the caudal peduncle 

 from the dorsal to end of scales, and another line of about equal length 

 and breadth, but more distinct, which extends along the lower edge of 

 the caudal peduncle from the last rays of anal to the caudal fin ; color- 

 ation of types very pale, probably a result of life in muddy water. 

 Length 1 inches. Rio Lerma, about Salamanca, Mexico; only male 

 specimens known, (infans, infant, from the small size.)

(Top MINNOW.) 



Head 3 to 4; depth 3 to 4. D. 7 to 9; A. 8 to 10; scales 29 to 32, 

 usually 30-8 to 10. Body rather plump, large specimens becoming deep. 

 Head moderate, very broad and much depressed ; teeth in broad villi- 

 form bands; eye moderate, 1 to If in interorbital width, 3 to 3| in head.
