9 , sometimes nearly x)laiii silvery, dusky olive above, and with much 

 minute dark specking on lower Lalf of sides ; sides usually showing 

 traces of from 12 to 15 narrow, silvery, vertical bars, less than one half 

 as wide as the dusky interspaces ; no white spotting on body or fins ; 

 fins all nearly plain dusky olive, with some yellow; top of head blackish. 



This species is very closely allied to F. heteroditus^ but differs con- 

 stantly in the much lower fins ; the interorbital width is slightly less, 

 and the fins show some slight differences in coloration. F. grandis was 

 found very abundant in the Laguna Grande at Pensacola, and was also 

 found at Galveston, Tex. 



23. Fundulus ocellaris sp. nov. (29667, 29667, 30853.) P. 



Head comparatively small and narrow, with short depressed snout, 

 and weak jaws; body rather slender; lower jaw but little longer than 

 upper; eye small, 4 in head. If in interorbital width, equaling snout, 

 which equals length of mandible; teeth all villiform, in narrow bands 

 in each jaw, the outer series but little enlarged, but projecting appre- 

 ciably beyond the others; i^reorbital narrow, less than half diameter of 

 orbit. 



Dorsal fin (in $ 3 inches long) much elevated, reaching, when de- 

 pressed, beyond base of rudimentary rays of caudal ; much shorter than 

 this in females and young males. Origin of dorsal midway between tip 

 of caudal and tip of snout, or slightly nearer snout; the base of the fin 

 li in height of longest ray, which is contained 1;^ in head; outline of 

 fin rhomboid, the upper edge straight, the last rays highest. Anal fin 

 similar to dorsal, but narrower and sliglitly lower, not reaching caudal 

 when depressed ; its origin under second ray of dorsal and distant from 

 caudal half as far as from tip of snout; base half height of lonjjest ray; 

 greatest height of caudal peduncle two-thirds its length and half length 

 of head ; oviduct not attached to first anal ray, but forming a low sheath 

 along base of first six rays. Caudal short, rounded, 1;^ in head ; pecto- 

 rals slender, reaching base of ventrals, Ij in head ; ventrals (in adult,?) 

 extending beyond front of anal, half length of head. 



Scales moderate, in somewhat irregular oblique series, of which there 

 are 35 between gill opening and base of caudal; 15 scales in an oblique 

 series from vent forwards to middle of back; about 18 cross series 

 between nape and front of dorsal; humeral scale not enlarged. 



Female with somewhat deeper body, and different coloration; the 

 fins smaller, tlie last ray of dorsal shorter than those preceding, and not 

 reaching halfway from its base to rudimentarj- caudal rays; length of 

 longest ray greater than base of fin; ventrals not nearly reaching vent; 

 front of dorsal nearer tip of caudal than end of snout. 



Head 3 to 3i in length ; depth 1. D. 11 ; A. 10 ; V. 6 ; P. 13; scales 

 35-15. 



Color: ^, dark olive brown above, golden on sides and below, the 

 golden tint extending farther upon caudal peduncle than on trunk;
