of the calculated regression line and of the co- 

 ordinates of specimens up to 830 mm. (fig. 90) 

 suggests that a decrease in eye growth rate occurs 

 between approximately 200 mm. and 250 mm. 



Snout. — The regression of snout length on 

 standard length is shown in figure 89 and table 

 20. A line fitted to this regression for specimens 

 from 15.3 to 164 mm. standard length shows a 

 proportional rate of increase for the two variates 

 within this size range (0.08-mm. increase in snout 



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

 Comparison of the extension of this calculated 

 regression line with larger specimens (fig. 91) 

 suggests that the snout growth may continue 

 at the same proportional rate up to 830 mm. 



GUI rakers. — Lower limb, 16 to 19; upper limb, 

 6 to 9; total, 22 to 27 (table 22). Of the 105 

 specimens examined that were more than 20 mm. 

 standard length, all but 2 (25 mm. and 33.5 mm.) 

 had one or more shorter or rudimentary gill
