 Mnierpes, JORDAN & EVEBMANN, Check-List Fishes, 468, 1896 (macrocephulus) . 



This genus is close to Lctbrisomus, from which it differs chiefly in the 

 very elongate body and in the absence of an orbital tentacle. The dorsal 

 spines are more numerous, and probably the vertebra) al>o. The lips are 

 thick and there is no trace of hook on the shoulder girdle. A band of 

 filliiorm teeth in the jaws behind the anterior series; teeth on voiner, none 

 on palatines, (jivior, moss; spTtrji:,, creeper.)

 13 ; V. I, 3 ; scales about 70.* The head is depressed, rather short, nearly
