 pelvic fin length to a standard length. 



Although the proportion and degree of damaged 

 fins should be the same for both populations, 

 a slight error will be introduced, and values pre- 

 sented for these measurements should be con- 

 sidered only as approximations of the real values. 



EYE DIAMETER, SNOUT LENGTH, 

 AND MAXILLARY LENGTH 



The values obtained for these characters were 

 similar in the Atlantic and Gulf populations, 

 with the Gulf population having a slightly larger 

 average value for all three characters (Tables 

 4, 5, 6) ; these values agree well with those of 

 Ginsburg (1954). 



All differences in these characters reported 



by Ginsburg (1954) may be explained by his 

 limited material. Material from other areas ex- 

 amined in the present investigation indicate 

 there are no differences between the two popu- 

 lations in any of the above characters (Figures 

 5, 6, 7).
