its original shape. All measurements were made with dividers and then read on the 

 rule, or the points marked by pins and measured with the tape. 



Snout to dorsal (SD). — Measured from the junction of the premaxillaries to the 

 base of the first dorsal ray. 



Snout to anal (SA). — Measured from the junction of the premaxillaries to the base 

 of the first anal ray. 



Dorsal to adipose (DA). — Measured from the anterior end of the base of the 

 dorsal fin to the anterior end of the base of the adipose.

I — length 

 sd — snout to dorsal 

 sa — snout to anal

 at— adipose to caudal 



ft — head 



o — occiput 



s— snout 



p — pectoral length

 db — dorsal base 

 ab — anal base 

 dh — dorsal height 

 oft— anal height 

 pv— pectoral-ventral distance 



to — maxillary 

 j — mandible 

 e— eye 



av— anal-ventral distance 

 d— depth 

 Ad — head depth 



Adipose to caudal (AT). — Measured from the anterior end of the adipose base 

 to the first of the upper procurrent caudal rays. 



Head (H). — Measured with dividers from the junction of the premaxillaries to 

 the extreme bony margin of the operculum, not including the opercular membrane. 

 This measurement, therefore, as given has not always been made parallel to the 

 longitudinal axis of the body. 



Head depth (HD). — Measured with dividers from the outer edge of the boundary 

 between the suboperculum and interoperculum to the base of the occiput.
