This fish inhabits Lake Erie *, where the specimens taken by M. Le Sueur had 

 their stomachs filled with fragments of river shells of the genera Cyclas, Paludina, 

 &c. This fresh-water species resembles the Corvina nigra of the Mediterranean 

 in its form, though its nape swells out still more. 



Its usual size is about seventeen inches in length, by nearly five in height. There are five 

 pores on the lower jaw, and its pharyngeal teeth are large, round, and flat (en gros paves 

 roods), serving to bruise the shell-fish on which it feeds. The stomach is a large, round, 

 blind sac, and there are seven thick cceca at the pylorus. The intestine is almost as wide as 

 the stomach, but its coats are very thin. The air-bladder is very large, without appendages, 

 and is covered with nacre. M. Le Sueur describes the colours of some specimens which he 

 found on the beach, where they had been left by the fishermen, as " bluish-grey on the head and 

 caudal-fin, drawing upon black on the snout and above the eyes, more grey towards the back 

 and above the pectorals : all the other fins are of a lighter grey : there were some red tints on 

 the cheeks, and a yellowish reflection on the sides of the back, tail, and opercula; the abdo- 

 men beneath the throat was white." (Le Sueur, I. c.)

The Otolithi are distinguished from all f the other Scisenoidese by the presence 

 of a tooth on each intermaxillary bone much longer and stronger than the others, 



* Cuvier says Lake Ontario, but M. Le Sueur, in the paper above cited, says Lake Erie, which is material, as it cannot 

 ascend thither from the sea, though it may into Lake Ontario. 



f Ancyladon jaculidens is considered, by Cuvier, as being really an Otolithus with a pointed tail, but differing from the 

 others in the shortness of its snout, and the extreme length of some of its teeth. A. parvipinnis resembles the Otolithi 

 also, but differs from them, and also from A. jaculidens, not only in the dorsals being very small, but also in their being per- 

 fectly separated from each other.
