Pre-orbital clistance (Pr.O.), from tbe tip of the snout to tbe anterior margin
of the eye.
Body deptb (B.D.), tbe vertical distance bet-ween the dorsal and ventral
profiles of the body, measured at tbe broadest part of the body.
All tbe preceding measurements were taken for 474 fisb of S. maderensis
ranging in lengt.b between 65 and 284 mm, and 463 fisb of S. aurita ranging in
length between 45 and 224 mm. l’he ratio of eacb of tbe previous measurements
to the standard length were made foI’ every SiIlgJe fisb and tben the average for
ea.ch centimeter lengtb group is calcula’tt’d. The avelage for all length gronps
was also obtained.
