FAMILY PERCIDA — POMOTIS. a5 
The above characters would seem to announce a new species. I have never met with it, 
and have adopted the description of Mitchill. Its broad appendix distinguishes it from P. 
solis, mentioned beneath. 
(EXTRA-LIMITAL.) 
P. ravaneli. (Cov. et Vat. Vol. 7, p. 465.) Back much arched ; denticulations very fine at the angle 
of the preopercle. D. 10.11; A. 3.9, Length eight inches. Sowth-Carolina. 
P. holbrooki. (In. Ib. p. 466.) Very large black spots on the soft rays of the dorsal ;" preopercle very 
finely denticulated. A. 3.11. Length nine inches, South-Carolina. 
P. incisor. (Ip. Ib. p. 467.) A single black spot on the soft rays of the dorsal appendix; long. D. 
10.10; A. 3.9. Length six inches. New-Orleans. 
P. gibbosus. (Iv. Tb. p. 467.) Longitudinal series of blackish spots along the back ; membrane of the 
opercle wide and striate. D, 10.11; A. 3.11. Length eight inches. Charleston. 
P. solis. (Ip. Ib. p. 468.) With no spots or stripes on the body or fins ; appendix very long and nar- 
row. D. 10.11; A.3.10. MNew-Orleans and New-York. 
P. catesbei. (In. Ib. p. 469.) Brown and oblique lines on its cheeks; blackish points on the dorsal 
and anal fins. Body elongated. D. 10.11; A.3.9. Length four and a half inches. Phila- 
delphia. 
Genus Bryrrus, Cuvier. A narrow band of velvet teeth on the outer edge of each palatine. The 
form and all the other characters of the preceding. 
Oss. Cuvier, to whom we are indebted for this genus, observes that it is impossible to find a 
greater resemblance than between this and Pomotis, the above character being the only one by 
which they can be contradistinguished. The three species following may prove to be simple 
varieties. 
B. punctatus. (Cuv. et Vat. Vol. 7, p. 462.) Black points on its cheeks and the sides of the abdo- 
men; first soft ventral ray filiform; appendix narrow, and not much elongated. D. 10.11; A. 
3.8. Length five anda half inches: South-Carolina. 
B. reticulatus. (Ip. Ib. p. 463.) Bright yellowish-green; base of each scale darker, so that the body 
appears as if covered with a net work. D, 10.11; A. 3.11. Length seven inches. South- 
Carolina. 
B. unicolor. (In. Ib, p. 464.) Only three or four teeth on the anterior part of the palatines. Fins 
unspotted. Color uniform. D, 10.11; A, 3.9. Length six inches, Pennsylvania, South- 
Carolina.
