With regard to the femalcs, Tables XV. and XVI. correspond to Tables IX. 

 and X. of the males and show the correhition between the carapace length and 

 Measurement No. 1 for the deep and shallow water forms respectively. 



Deep water r = -S^GG ± -0088, 

 Shallow water r = -8428 + -0083, 

 Difference 0037+0121. 



The difference being less than its probable error is quite uegiigible.
