FAMILY CYPRINID.E LEUCISCUS. 213 



low down. Ventrals broad and rounded, beneath the dorsal. Anal similar in shape to the 

 dorsal, but not so high; its upper edge slightly emarginate. Caudal deeply forked. 



Color. Body above light-olive green, with a golden dorsal stripe extending to the tail. A 

 faint broad yellowish stripe along the sides, which in certain lights assumes a darker hue. 

 Abdomen silvery, tinged with salmon-color. Pupils black ; irides light brown. Summit of 

 the head olive-brown. The fins yellowish, translucent. 



Length, 4-0. Depth, 0-8. 



Fin rays, D. 9 ; P. 15 ; V. 8 ; A. 8 ; C. 19 f . 



This small species is very common in the Chittenonda and other tributaries of the Mohawk. 

 In the latter stream, they are abundant in the " pot-holes," or circular cavities made in its 

 limestone bed. 



THE CORPORAALEN. 



Leuciscos'? corporalis. 

 Corporal, Cyprinus corporalis. Mitchill, Am. Month. Mag. Vol. 2, p. 324. 



Description. Head smooth, roundish, thick, and without scales. Body thickly covered 

 with scales : On the back, more especially between the head and dorsal fin, the hue is dusky ; 

 on the belly, it is uniformly white ; and on the sides, the fore part of each scale is covered 

 with a blackish film or pigment. Mouth toothless, and of a moderate gape. Tongue distinct, 

 not free. Gill-covers smooth. Tail forked; the lateral line bends downwards and ends in 

 the middle of the tail. Branchial rays three. Dorsal fin near the middle of the back, and 

 consists of seven rays ; caudal of nineteen, or thereabouts ; the anal seven ; the ventral seven ; 

 pectorals thirteen ; the dorsal and caudal fins tipped with blackish. Length of a middle sized 

 individual about thirteen inches, though he frequently grows larger. Inhabits the Hudson in 

 the neighborhood of Albany, the Walkill through its whole extent, and the western streams 

 and lakes from Wood creek to the Oneida lake, and so on. Takes the hook, if baited with 

 dough, when let down through holes in the ice, at mid-winter, in the Hudson at Albany. 

 Flesh eatable, but rather soft and coarse. 



I have copied this brief account of a fish which, according to Dr. Mitchill, is common in 

 almost every part of the State, but which it has not yet been my good fortune to meet with. 

 I solicit the attention of ichthyologists to this species, which, if it should prove to be a Leu- 

 ciscus, is one of the largest of the genus.
