Genus AngUILLA (Thunberg), Cuv. Kegnc Anim. 

 Anguilla vulgaris, Turt. ; Gthr. op, cit. viii.p. 28. 

 Abundant in the streams joining the sea, and occasionally 

 between tide-marks; but tin' latter occurrenoe is rare in con- 

 trast with the western and southern shores. 



Anguilla Intirostn's, Risso ; Gthr. op. cit. viii. p. .'52. 

 Not uncommon in similar Idealities. A curious instance of 

 the fatal effects of the voracity of this fish was found in the 

 Swilken burn. A specimen about 20 inches long had seized 

 the head of another not much shorter than itself, and attempted 

 to swallow it. In its struggles the victim's tail also entered 

 the mouth of the Larger, and passed out at the left gill-slit, 

 so that several inches were free (Plate All I. fig. 111. The 

 body of the victim thus formed a large loop which could 

 not be swallowed, while the impaction of the head and tail, 

 and the direction of the teeth of the large specimen, pre- 

 vented the ejection of the prey. The marauder became 

 exhausted, and was captured at the edge of the stream a 

 the sands. 



Genus Conger, Cuv. 



Conger vulgaris, Cuv. ; Gthr. op. cit. viii. p. 38. 

 Abundant in deep water.
