hundred and twenty-five are common to the torrid and temperate 
zones. 
Yet it is seen from the table, that if we except the Galatheidea, 
. Lithodea, aud part of the Paguridea, the species hardly extend 
beyond the warmer half. of the temperate zone. "l'here are but 
six known frigid species, and these are of the two last-mentioned - 
groups.

The Dromidea and Pisas have one-third to one-fourth 
more torrid than cold-water species. 
'The Raninidea and Hippidea are mainly tropical. 'The two 
extra-tropical species of. Raninidea occur only in the warmer of 
the temperate regions, and the species of Hippidea in the tem- 
perate zone (eight out of the whole number fourteen) have 
among them four that occur also in the tropics.
