COBITIS LARVATA. 255 



midway between the eye and the extremity of the snout. The sub-orbital 

 spine appears to be relatively shorty, on account of the large size of the fish. 



Another variety, named by Filippi Cob'dis larvata, is found in Piedmont. 

 The head is one-fifth of the length of the body, and uniformly brown. There 

 are six pharyngeal teeth in each bone. A brown band extends along the 

 trunk, and becomes broken into spots on the tail. There are two brown spots 

 at the base of the caudal fin. The bony capsule for the air-bladder is larger, 

 and the fish swims better than C. tmiia. The sub-orbital spine is capable of 

 being raised from a cutaneous fissure.
