FISHES OF OKEFINOKEE SWAMP 
365 
A glance at the above makes it evident that the head, snout or 
eye of E. vermiculatus may be larger or smaller than that of 
B. americanus. The characters are of little value. Our ten speci- 
mens show the following measurements: H, 2 5/6-3 1/5, Sn. 
2 1/2-2 3/4, E. 5 1/2-7. 
The fin formulae for the two species are identical or overlap- 
ping. Previous descriptions give the following: E. americanus, 
D. 11-14, A. 11-12; E. vermiculatus, D. 11-12, A. 11-12. Our 
specimens have D. 12-14, A. 11-13. 
The color characters used to determine the species are almost 
invariably qualified as “usually’^ ‘‘sometimes”, “about”, “ob- 
scurely”, “not distinctly” and the color is described as being 
“extremely variable.” In view of this fact we can see no basis 
for recognizing two species on color characters alone, when color 
is so tricky in this genus, as many know who have worked with 
young of E. lucius and E. reticulatus and with adults of supposed 
E. americanus and E. vermiculatus. 
An examination of the food of our ten specimens reveals 
crayfish and killifish as the major sources of prey. 
Esox reticulatus (Le Sueur). 
“Jack-fish,” Green Pike, Chain Pickerel, Common Eastern 
Pickerel, Jack. 
Only five specimens of this species are in our collection. While 
wq were in the swamp the Lees caught several fine “jackfish.” 
When the water is high this species is one of the forms which these 
people capture by “striking”, a night method of fishing in the 
overflowed crossways and edges of the islands. 
Fundulus cingulatus Cuvier and Valenciennes. 
The recorded range of this form is from South Carolina to 
Florida. Our Okefinokee series of this species consists of ninety- 
five specimens of sixteen different collections. It is one of the 
most widespread species of the swamp and vies with Gambusia 
for the premier honors in abundance. Woolman found it com- 
mon in Santa Fe river of this same basin. 
The difference between descriptions of Fundulus chrysotus 
Holbrook and Fundulus cingulatus Cuvier and Valenciennes in 
head, depth and eye measurements are so slight as to be non- 
distinctive. 
This species was common in all the prairies and in every little 
pond or swampy spot in the islands or in transient pools which
