In Tables VI, VII and VIII are given the counts for the anal, spinous dorsal 
and soft dorsal fins, respectively. The per cents. are based on 1,475 specimens of 
all ages from Tippecanoe Lake and 850 of all ages from Turkey Lake. 
C. Anal Rays.—From Table VI, it will be seen that the anal fin is somewhat 
larger in Tippecanoe Lake than in Turkey Lake. This is shown by the decrease 
in the per cent. of specimens having the prevailing number, 11, and the increase 
in the per cent. of specimens having the next lower number, 10, in the Turkey 
Lake specimens. The mean number of rays is 10.76 for Turkey Lake and 10.97 
for Tippecanoe Lake.

3. Dorsal Spines.—The dorsal spines in the Tippecanoe Lake specimens vary 
from 10 to 17. The prevailing number is 14, 61.44 per cent. having this number. 
The variation is slightly greater toward a higher number than toward a lower 
number of spines. In Turkey Lake specimens the spines vary from 12to 18. The 
prevailing numbers are 14 and 15, 42.57 per cent. and 43.48 per cent. respectively 
having this number. From these the variation is symmetrical in both directions. 
The mean is 14.20 for Tippecanoe Lake and 14.56 for Turkey Lake.
