p- 347. 
Head subconical; eye above the angle of the mouth; teeth in bands in the jaws and on the vomer. Body 
covered with oblong imbedded scales which are arranged obliquely at right angles to each other; dorsal 
and anal fins well-developed, confluent round the end of the tail; pectoral fins present. 
The number of valid species of this widely distributed genus is probably not more 
than five or six. ‘Ihe American form appears to be nearly identical with the 
European eel, Anguilla vulgaris, but it is generally regarded as distinct by American 
ichthyologists.
