70 ICHTHYOLOGIA O HI EN SIS 



a triangular bone beneath, covered with large round 

 hollow and obtuse teeth. Gill cover with two pieces, 

 preopercule slightly denticulate at the base, oper- 

 <;ule without teeth nor spines : branchial membrane 

 with six rays. Two dorsal fins contig[u]ous, the first 

 spiny, the second partly so, scaly along the base. 

 Vent posterior. 



This genus was called by me Aplodinotus G. 8. of 

 my Memoir on 70 New Genera of American animals, 

 in the journal of Natural History of Paris, having 

 been led into error, in supposing that the remarkable 

 teeth of its throat belonged to the Buffalo fish, as 

 will be seen below. The name means obtuse teeth. 

 It differs from the G. Sciena by the scaly head, oper- 

 cule and base of second dorsal fin, besides the singu- 

 lar teeth. Only one species is known as yet. 



4th Species. Grunting Bubbler. Amblodon grun- 

 niens. Amblodon grognant. 



Synonymy. Sciena grunniens Raf. Catal, fishes 

 of Ohio. Aplodinotus grunniens. Raf. Mem. on 70 

 N. G. Animals, G. 8. 



Entirely silvery, upper lip longer, lateral line 

 curved upwards at the base, bent in the middle, and 

 straight posteriorly, tail lunulate, first dorsal fin with 

 nine rays, the first very short, the second with 35 

 rays, the first spiny and short. 



The vulgar names of this fish are White-perch, 

 White-pearch, Buff aloe-perch, grunting-perch, bub- 

 bling-fish, bubbler, and muscle-eater. It is one of 

 the largest and best found in the Ohio, reaching 

 sometimes to the length of three feet and the [I. 373] 

 [25] weight of thirty pounds, and affording a delicate 

 food. It is also one of the most common, being 

 found all over the Ohio, and even the Monongahela
