 spine obsolete. Gill-rakers rather long and slender, 5 + 14 in number, 

 the longest two-thirds eye, 3f in maxillary, their length 4 to 5 times their 

 breadth at base. Scales very small, not ctenoid, with few accessory

 a rather narrow bony ridge, anteriorly naked, not wider than pupil (in 

 specimen 8 inches long), the ridge extending backward, forming a con- 

 spicuous elevated rim behind upper eye. Pectoral about half length of 

 head; caudal . Head 3*; depth 2J. D. 88; A. 67; Lat. 1. 90. One 

 specimen known; from Charleston, S. C. 



P. dcaatatus (L.) J. & G. Common flounder.
