coordinates of specimens larger than 145 mm. 

 fall along the extension of the calculated regres- 

 sion line, indicating that snout growth may 

 continue at the same proportional rate. 



Gill rakers. — Lower limb, 23 to 28; upper 

 limb, 10 to 14; total, 35 to 42 (table 5). Nichols 

 (1938b: 2) listed a range on the lower limb of 

 25 to 33 (his average, 27.9) for 28 specimens. 

 In view of the maximum number on the lower 

 limb (28) obtained by Ginsburg (1952: 97) 



and myself, abnormal specimens might account 

 for the high number reported by Nichols. 



About 20 percent of the specimens above 20 

 mm. had 1 or 2 rudimentary gill rakers at the 

 origin of the lower limb; none on the upper limb. 

 The presence or absence of these rudiments is 

 apparently independent of body size relationship, 

 as the specimens possessing rudiments were 

 interspersed throughout the range of sizes 

 examined.
