The free ra3's of Colotrhjla^ inserted high up as they are and quite

There is another species of Triglid, referred to Prionotiis by pre- 

 vious authors and much more nearlv related to the typical species than 

 the P. steitnt.sH, which exhibits a remarkable deviation from all the 

 other species of that genus; it is the I\ alatus. Each pectoral tin 

 is divided into two parts, an upper of 7 or 8 rays diminishing down- 

 ward, and a lower of 6 or 7, whose uppermost ray is very long and 

 the lower rapidly graduated downward. This singular character is 

 worthy of subgeneric recognition at least, and the subgenus may be 

 named Fissala.
