FISHES OF NORTH CAKOLINA. 



This species, which Uves on rocky bottom in rather deep water off Charleston, 

 South CaroUna, is also known from the North Carolina coast at Beaufort. Dr. 

 Jenkins obtained a few specimens in Beaufort Harbor in 1885. In the summer 

 of 1902, 8 specimens were taken in a trawl by the steamer Fish-Hawk near the 

 sea buoy off Beaufort Inlet; and 2 others, 4 inches long, were seined on Bird 

 Shoal in Beaufort Harbor in 1903. The maximum size is about 1 foot.

 3.33 times in length; mouth large, maxillary extending to pupil, lower jaw the longer; eye .2 

 length of head, shorter than snout; preopercle with finely serrate upper margin and 2 patches 

 of divergent spines; gill-rakers 14 or 15 below angle of first arch; scales in lateral series 80 to 

 90, in transverse series 30; numerous rows of scales on cheeks and opercles; dorsal rays x,12,

This beautiful little serranid, which ranges as far south as Uruguay, has not 

 heretofore been recorded north of Charleston, South Carolina. In the summer 

 of 1903, 4 young specimens were caught in the laboratory seine in Beaiifort 

 Harbor. The species is usually found on sandy shores, takes the baited hook 

 readily, reaches a length of a foot, and is a good food fish.
