Takinjiall thespe(;imeiis recorded (.'500), addiii},' the columns, and roprcseiitii. 

 variations in the anal rays in a curve,* we find that there is a certain number ol •><> 

 ders or peaks. Each of these rei»re.sents a distinct sjiecies or variety. The cMi 

 iiiterji:radatioii can be measured Ity tlie deptli of the valley between any two i-'**" 

 In well separated species the slopes of the two peaks would not meet. Now it v 

 noticed that the depth of the valley between tlie two right peaks is (piite .sli 

 and, ill fact, 1 lind the variation almost jierfect between L. ImUvntus and liitnul' 

 two varieties reinesented by these two jteaks. The valley between the iiiiiM/ 

 and the two on the left is deep. In other words, L, Uiicralis is well separated o- 

 eharacter under consideration from L. InjdrophJo.r and uioutunim, the speci 

 seiited by the i)eak to the left. On the other hand,tlu; latter species luerfr*' in' ° 

 other jierfectly in the number of rays.
