Plate V. Fig. 3, teeth. 
B. 5: D. 8-10; A. 10-9; V.6; P. 15-16; Ll. 28-29; Ltr. 9. 
Short and deep; caudal pedicel deep. Head depressed, broad, flat on the 
crown, equal the depth between dorsal and anal or one fourth of the length 
to the base of the caudal. Snout as long as the eye, broad, truncate ; chin 
short, steep. Mouth wide, directed upward; jaws weak, loosely joined, 
lower short, upper shorter, protractile. Outer series of teeth slender, oar- 
shaped, hooked, movable ; inner in bands, small, pointed. Eye large, as long 
as snout, half of interorbital space, two sevenths of head. Dorsal larger than 
anal, origin midway from head to base of caudal, over third ray of anal, thir- 
teen scales behind the occiput. Anal small, acute angled, third ray longest. 
On the male the base of the anal is forward of that of the dorsal, the fin is 
modified to form a sharp pointed organ in which the rays are less changed 
than in most species; its length is less than that of the head. Ventrals 
small, not reaching the anal. Pectorals reaching back over seven scales. 
Caudal deep, as long as the head, hind margin rounded. Scales large. 
Intestine long. 
Brownish, olive tinted, bases of scales dark, back darker and top of head 
darkest. More or less of the hind margin, or half of the scale, is whitish to 
silvery on the scales of the flank. Lighter to silvery under head and abdo- 
men. Dorsal with one to several transverse series of small spots of black ; 
fin sometimes black tipped. A brownish streak extending back and upward 
on the opercle behind the eye. Caudal with small spots of black on the 
basal half, or with a couple of clouded transverse bands. Other fins uniform 
or puncticulate. Very small ones are lighter with a faint silvery band along 
the middle of the flank but without vertical bars. A large one has numer- 
ous small white spots, somewhat like Fundulus heteroclitus. Females two 
and a half and males one and nine tenths inches.
