14 NEW-YORK FAUNA. 



with the dorsal outline. Head small and pointed. Eyes large, 0'5 in diameter, and slightly 

 more than their diameters apart. Nostrils double, contiguous, vertical, slightly in advance of 

 the orbits. Suborbital scaly. Preopercle with about fifty stout teeth on the posterior margin, 

 more robust on the rounded angle, smooth beneath. Opercle with two small spines separated 

 by a deep notch, which is filled up by membrane. Lower jaw slightly longest ; both with 

 bands of small subequal acute teeth : similar, but smaller teeth on the vomer and palatines ; 

 a small oblong patch of minute teeth on each side of the tongue, and a larger rounded patch 

 of similar teeth at its base. 



The first dorsal fin composed of nine spinous rays, arising at a point vertical to the origin 

 of the ventral : the first spine short, not exceeding a quarter of an inch in length ; the second 

 twice the length of the first ; the third more than twice the length of the second ; the fourth 

 and fifth subequal, longest ; thence gradually diminishing in size to the last, which is more 

 slender and rather longer than the first. The second dorsal arises a short distance behind, 

 and perfectly distinct from the first ; composed of one spinous and thirteen branched rays. 

 The spinous ray is robust, and half the length of the first articulated ray, which, with the 

 two following, are longest ; the last ray longer than the two or three preceding : this is not 

 faithfully rendered in the figure. Pectoral fins small, pointed, of seventeen rays ; the upper 

 simple, short ; the third and fourth longest. Ventral fins slightly behind the base of the 

 pectorals, robust, with one stout sharp spine and five branched rays ; the tips with a tendency 

 to filamentous. Anal slightly emarginate, with three spinous and twelve branched rays ; these 

 rays, as well as those of the second dorsal fin, have elongated scales extending towards the 

 tips. The first spine is short, the second twice the length of the first, and the third rather 

 longer than the second, but not more than half the length of the first soft ray. Caudal fin 

 deeply lunate, with scales ascending high on the rays. 



Color. Bluish white above the lateral line, with a few narrow parallel dusky streaks above 

 and beneath this line. Sides and belly white. Pupils black ; irides white, intermixed with a 

 little brown. Dorsal, caudal and anal fins brownish, tinged with blue. Pectoral fins whitish, 

 tinged with olive green. Ventral fins light transparent bluish, tipped with white. 



Length, 10*5. Depth, 3-0.

This is a very common fish in Lake Erie, and is known at Buffalo under the name of 

 White Bass. It readily takes the hook, and is esteemed as an article of food.
