Before commenting further on this character, in 

 table 23 we have compiled the numbers of oblique 

 scale rows counted (with exceptions noted) along 

 the fii-st row of scales above the lateral line. In 

 discussing the lateral scale count, it is instructive 

 to compare the results of counts made on the 

 lateral line and counts made one row (or more) 

 above the lateral line. This comparison is shown 

 in table 2-i and figure 8. 



It may be noted in comparing the number of 

 vertebrae (fig. 5) with tlie number of lateral-line 

 scales (fig. 7) that the different species maintain 

 approximately the same ranking in the two char- 

 acters (see table 24) . Even though for several of 

 the species the vertebral counts and scale counts 

 are not all — in some cases none — from the same
