THE HABITS OF TYPICAL ANTENNARIIDS. 



Very little is knowm of the habits of most of the Pediculates, but 

 considerable has been ascertained of the peculiar characteristics of 

 species of the best-known genera of the family of Antennariids. 

 This has been collected here from many sources. 



ANTENNARIUS. 



The genus Antennarius has the body covered with prickles or 

 minute si^inules, the mouth is subvertical, the caudal peduncle free, 

 the wrists and pectoral fins wide, the pectorals entire, the ventrals 

 short, the dorsal fin (12) moderate and less than half as long as the 

 body, the third dorsal spine more or less concealed below the skin, 

 and the anal oblong and provided with seven or eight rays. 



Such are the characters which serve to distinguish the genus from 

 PteropJiryne as well as Rhycherus, Histiophryne^ Saccarius, and 

 Tafhicarpm ; other genera of the same subfamily are so far removed
