21. Zygonectes henshalli Jordan. 



Still more abundant. This species and the preceding are very closely 

 related, and are both nearly intermediate between Zygonectes and Fundti- 

 lun. The current genera related to Fundulus are separated by characters 

 of very dubious value. 



22. Fundulus sj). 



A small specimen with pale cross-bars; not suitable for identification. 



23. Gambusia patruelis B. & G. 



Two specimens, agreeing with the descriptions of Gamhusia holbrooki 

 of Girard and Giinther, and with Girard's figure of Gamhusia patruelis. 

 The two species are probably identical. The black bars on the caudal 

 and the oblique suborbital blotch are characteristic color-marks. 



CATOSTOMID^. 



24. Erimyzou goodei Jordan. 

 Many specimens. 



SILURID^. 



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 3| times in the total 

 leugtli of the fish. In Florida specimens 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 

 couiineiicements of the dorsal and anal fins." 



And to A. bostonicnsis (rostrata) — 



'•The length of the head is conspicuously more than the distance be- 

 tAveeu 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.
