As will be seen by the foregoing figures, the width of the interocular 

 space, the length of the pectorals, that of the caudal peduncle, and the 

 number of rays in the dorsal, are very variable. 



In the stomach of an example 7^ inches in length were the half- 

 digested remains of two anchovies {EngrauUs ringens) each about three 

 inches long. 



This is the most common of the species sold as " Sole" in the markets 

 of this city. Most of the individuals brought to market are from ten to 

 twelve inches in length; but many reach sixteen or even eighteen inches. 

 The black dots over the upper side, the long anterior dorsal rays, in- 

 serted more in advance than is usual, and the small eyes, render this fish 

 easy to recognize.
