Snout. — The regression of snout length on 

 standard length is shown in figure 42 and table 7. 

 A line fitted to this regression for specimens from 

 12.4 to 88.5 mm. standard length shows a propor- 

 tional rate of increase for the two variates within 

 this size range (0.09-mm. increase in snout length 

 per 1.0-mm. increase in standard length). The 



alinement of coordinates of specimens larger than 

 88.5 mm. above the extension of the calculated 

 regression line indicates that an increase occurs in 

 snout growth rate at about that size. 



Gill rakers. — Lower limb, 31 to 35; upper limb, 

 10 to 14; total, 42 to 47 (table 9). About 15 

 percent of the specimens had one shortened or
