%c of the body length, 165 exactly as in the 
males. 
There is little or no asymmetry in the length 
of the right and left testes, but in males the 
right kidney is about one-fourth longer than the 
left one. 
INTERVALS: The interval between the pan- 
creas and the left kidney is 234 %© of the body 
length in the male animals, 248 %c in the 
female. 
LUNG: In these two young animals there is 
no difference in the topography of the lung: in 
the male the apex is at 270 %o, in the female 
at 27 6 %c\ the end of the trabecular part of 
the lung is at 384 %o, resp 380 %o of the 
body length. In the female only, the end has 
been noted rather far to the caudal end of the 
body ( 896 %o ) . 
SHIELDS: In one male and in the female the 
number of shields is counted: the figures are 
given in Table 15. There is no difference be- 
tween the sexes.
