primary row (Figure 5B and C). The number of 

 ctenii on cheek scales varies from 5 to 8, while 

 scales from the dorsal and anal fin bases at the 

 greatest body depth have 15 to 25 ctenii. 



The general arrangement of teeth in the upper 

 and lower jaws is shown in Figure 6. There 

 are usually three rows of teeth. The outer row 

 consists of a few, stout conical teeth in the 

 anterior portion of the jaws. The middle row 

 consists of more numerous, but less stout, conical 

 teeth. The inner row consists of depressed, poor- 

 ly ossified conical teeth subequal in number to 

 those in the middle row (except on the blind side 



of the upper jaw). The inner row of teeth are 

 movable, being held in place by flesh and not 

 inserted in the jaw bones. 



The number of outer teeth, and, to a lesser 

 extent, the middle teeth, vary according to jaw 

 bone and size of specimen. This is illustrated in 

 Figure 7 where the number of teeth are plotted 

 by standard length for 10 females 49.2-106.4 mm 

 SL and 10 males 55.8-114.5 mm SL. The increase 

 in number of outer teeth with size is ai)parent 

 for all jaw bones except the dentary on the ocular 

 side. There also appear to be more outer teeth in 

 the premaxillary of the ocular side of the males.
