Class C: 129 specimens with spots i 1 and i r well defined 

 (fig- 57, c). 



Class D : 5 specimens with spots i 1 , i r , 3 1 and 3 r present (fig. 

 57, d). 



Class E : 24 specimens with spots i 1 , i r , 4 1 and 4 r present (fig. 



57 *). 



Class F : 7 specimens with spots i 1 , i r present and 2 1 2% 3 1 

 and 3 r dimly indicated (fig. 57,./"). 



Class G : 16 specimens with spots i 1 , i r , 2 1 , 2 r , 4 l and 4 r pres- 

 ent (fig. 57, g). 



Class H : 2 specimens with spots i 1 , i r , 3 1 , 3 r 4 1 and 4 r pres- 

 ent (fig. 57, h). 



Class 1 : 17 specimens with spots i 1 , i r , 2 1 , 2% 3 1 and 3 r pres- 

 ent and 4 1 , 4 r , dim or absent (fig. 57, /, i). 



Class J : 43 specimens with spots i 1 , i r , 2 1 , i r , 3 1 , 3 r , 4 1 and 

 4 r well defined (fig. 57, /). 



Class K : 20 specimens with spots i 1 , 2 1 and 3 1 and i r , 2 r 

 and 3 r coalescent and 4 1 and 4 r dim or absent (fig. 57, k, k). 



Class L : 68 specimens with spots i 1 , 2 1 and 3 1 and i r , 2 r 

 and 3 r coalescent and 4 1 and 4 r well defined (fig. 57, /). 



Class M : i specimen with spots i 1 , i r , 2 r , 4 1 and 4" well de- 

 fined and with 2 1 , 3 1 and 3 r dim (fig. 57, m). 



Class N: 4 specimens with spots i 1 and i r present and an 

 additional dim spot between i 1 and the position of 4 1 , and i r 

 and the position of 4 r (fig. 57, n). 



Class O: specimens with spots 4 1 and 4 r present (fig. 57, o). 



Class P : 3 specimens showing strong tendency to longitu- 

 dinal markings (fig. 57, f). 



The variations seem to cover most of the possible combina- 

 tions afforded by the possibilities of any one or more of eight 

 spots being absent, dim, or well defined. The bilateral cor- 

 relation of the variations is pronounced ; indeed there is but 

 one exception noted (Class M). The mode is the presence of 

 spots i and i alone, but well defined (Class C ; Class B is really 

 but a subdivision of the mode). Next to the modal class comes 

 that in which all the spots are present, with three on each side 

 coalesced to form a diagonal line (Class L; Class K is also 

 but a subdivision of this next to the modal class). Third
