with the insects they pursue, and the king-fishers and wading birds which 

 they attract and support, a very lively and interesting part of the scene, to 

 those whose attention has been once directed to the circumstance. 



IV.— Gen. LEUCISCUS. 



The Abies, or white fishes, were distinguished by Klein, a naturalist of the 

 last century, by the following characters—" Dorsal and anal short ; neither 

 spines nor cirri, and nothing particular about their lips." Cuvier, however, 

 observes that species with cirri occur, and instances Cyp. danrica, Buch., and 

 although I have referred that species to the Perilamps, still I have replaced it 

 by Cyp. cocsa, Buch., as well as Cyp. elanga, id, both of which have cirri. 

 Cuvier in addition to Klein's characters distinguished Leucisci into smaller 

 divisions, according to the position of the dorsal fin, which he remarks is not 

 always clear. The genus, he observed, is rich in species ; but this is the case 

 with all ill defined groups, it being often as difficult to determine what does 

 not, as what really belongs to them. 



Leuciscus teoprius, J. M. 



Dorsal and anal small, without spines, the last ray of the former placed 

 anteriorly to the first of the latter fin, so as to bring it at least opposite the space 

 between the ventrals and anal, if not opposite to the ventrals. The sides are 

 white and silvery, presenting little variety of colour ; the scales are covered 

 with a pearly pigment; the mouth is either horizontal or directed upward; the 

 lower jaw is armed with one or more blunt prominences, or where these are 

 wanting, its apex is received into a fissure in the upper jaw. 



The stomach and intestines are scarcely longer than the body, the inter- 

 maxillaries are not protractile.
