THE OATFISHES OF VENEZUELA SICHULTZ 307 



everywhere dark brown to blackish with the dorsal surface anteriorly 

 in front of dorsal fin with numerous round pale spots ; these spots are 

 oblong and larger on the belly, occurring as far back as the anal fin; 

 on the young the belly is plain blackish; none of the spots join each 

 other; a black spot occurs at base of membrane of dorsal fin between 

 the spine and first soft ray; all of the fms are very dark, and with 

 four or five bars ; tips of first rays of dorsal pale ; tips of rays of upper 

 and lower lobes of caudal fin pale; a pale bar across base of caudal 

 fin rays on caudal peduncle; pectoral fins barred, pelvics barred. 



Remarks. — This new subspecies is related to A. triradiatus martini, 

 new subspecies, but differs in certain counts. It is closer to A. 

 hremfilis hrevifilis Eigenmann in regard to counts. However, brevifilis 

 lacks a black spot at base of dorsal between the spine and first soft 

 ray; in addition, bodenhameri docs not have faint darker spots about 

 size of eye in front of the dorsal and the belly is not uniform in color 

 as in hremfilis. 



Named bodenhameri in honor of Raymond L. Bodenhamer, of the 

 Lago Petroleum Corporation, who aided me greatly in regard to 

 transportation while I was in Venezuela.
