ages; that, further, the distance between the epibranchial teeth, as com- 
pared with that between external orbital angles, is generally greater in 
the © than in the © (though the proportion between both sexes may be 
sometimes nearly equal: &/ n°. 3 and 4, © n°. 8 and even the reverse 
may occur); and that, finally, the posterior margin is indeed half the 
length of the carapace, and much shorter than the breadth of the front, 
in the /, whereas in the © the posterior margin is proportionally much 
longer, and the breadth of the front in some cases is more, in other less 
than the length of the posterior margin. There seems to be no relation 
whatever between the age and the proportional dimensions of the in- 
dividual.
