 points of measurements. 



Letters indicate 



ments of standard length to show size range of 

 specimens captured are indicated to the nearest 

 0.5 mm. All body lengths are expressed in stand- 

 ard length. 



Percentages are indicated to the nearest 0.1 

 percent. 



The upper lip was not included in the measure- 

 ments involving the tip of snout. 

 A-B. — Snout length. Tip of snout to anterior 



edge of bony eye socket. 

 B-C. — Eye diameter. Horizontal width of bony 



eye socket. 

 C-E. — Postorbital head length. Posterior edge 

 of bony eye socket to posterior edge of 

 operculum, inclusive of spine if present. 

 A-E. — Head length. Tip of snout to posterior 

 edge of operculum, inclusive of spine if 

 present. 

 A-F.— Snout to first dorsal. Tip of snout to 

 base of first spine of spinous dorsal. 

 A-G. — Snout to second dorsal. Tip of snout to 

 base of first ray of soft dorsal. 



A-M. — Snout to anal. Tip of snout to base of 



first spine of anal fin. 

 D-L. — Depth. Measured at deepest point, 



slightly anterior to first dorsal fin to 



origin of pel vies. 

 H-I. — Dorsal lobe oj caudal. Origin of first 



secondary ray of dorsal lobe to tip of 



longest ray of dorsal lobe. 

 N-P. — Ventral lobe of caudal. Origin of first 



secondary ray of ventral lobe to tip of 



longest ray of ventral lobe. 

 J-K. — Barbel length. Anterior edge of base of 



barbel to tip of longest barbel.

end of hypural bone (base of midcaudal
