172 NEW-YORK FAUNA. 



FAMILY XVI. L ABRIDGE. 



Jaws covered by fleshy lips. Tongue and palate smooth and toothless. Three pharyngeals : 

 two above, and one beneath ; all furnished with teeth, either paved or flattened, or pointed. 

 Body oblong, scaly. A single dorsal, with Hie anterior rays spinous. An air-bladder. 

 No ccecal appendages. 



Obs. This family, as established by Cuvier, comprises three hundred and fifty-one species, 

 arranged under twenty-two genera. They appear to be most numerous in warm latitudes ; for 

 on the coast of New-York we have only the representatives of two genera, comprising a very 

 limited number of species. Other genera will doubtless be found on the coast bordering on 

 the Gulf of Mexico. 



GENUS CTENOLABRUS. Valenciennes. 



Body elongated, scaly. Preopercle denticulated. A band of velvet-like teeth in front, behind 

 the conical teeth in the jaws. Three, spinous rays to the anal fin. 



Obs. This genus has been lately separated by M. Valenciennes from the genus Crenilabrus, 

 with which it has many characters in common. 



THE COMMON BERGALL. 



Ctenolaercs ceruleus.

 six above and seventeen below the lateral line. Lateral line near the back, concurrent with 

 it, and of course not much curved ; descending rather suddenly opposite the termination of 

 the dorsal fin. Head gradually sloping ; the facial line slightly convex before the dorsal fin.
