21. Zygonectes henshalli Jordan. 
Still more abundant. This species and the preceding are very closely 
related, and are both nearly intermediate between Zygonectes and Fundu- 
lus. The current genera related to Fundulus are separated by characters 
of very dubious value. 
22. Fundulus sp. 
A small specimen with pale cross-bars; not suitable for identification. 
23. Gambusia patruelis B. & G. 
Two specimens, agreeing with the descriptions of Gambusia holbrookt 
of Girard and Giinther, and with Girard’s figure of Gambusia patruelis. 
The two species are probably identical. The black bars on the caudal 
and the oblique suborbital blotch are characteristic color-marks. 
CATOSTOMIDA. 
24. Erimyzon goodei Jordan. 
Many specimens. 
SILURIDA. 
25. Amiurus erebennus Jordan. 
Many small specimens. 
ANGUILLID/&. 
26. Anguilla rostrata (Le Sueur) Dek. 
A comparison of these Florida specimens with a series of eels from 
Venice renders it evident that our American eel is not identical with 
Anguilla vulgaris of Europe, as I with others have supposed. 
In our species the beginning of the dorsal is notably more posterior 
than in the European one. In Venetian specimens the distance from 
the snout to the base of the dorsal is contained 32 times in the total 
length of the fish. In Floridaspecimens the same distance is contained 
barely 3 times in the total length. 
The same difference is expressed differently but correctly by Dr. 
Giinther (Cat. Fish Brit. Mus., VIII, 24). He ascribes to A. vulgaris 
the character of— 
“The length of the head is nearly equal to the distance between the 
commencements of the dorsal and anal fins.” 
And to A. bostoniensis (rostrata)— 
“The length of the head is conspicuously more than the distance be- 
tween the commencements of the dorsal and anal fins.” 
The band of vomerine teeth also appears to extend farther back in 
A. vulgaris than in A. rostrata.
