GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. 1489 



We give first a table of the Brachyura, and following this, a recapitu- 

 lation and summary, containing a summing up of the species for the 

 subfamilies, families, tribes, &c. These tables afford some obvious 

 deductions. Then follow similar tables for the Anomoura, Macroura, 

 and remaining Podophthalmia, with a series of deductions ; and then 

 the same for the Tetradecapoda. 



The perfecting of the Temperature Chart, by changing the limits of 

 some of the regions (which is to be expected as new facts are brought 

 in), will undoubtedly cause some modifications of these tables; but 

 nothing that will affect essentially the conclusions which will here be 

 drawn from them.
