GECARCINIDiE. 
The respiratory cavity beneath the dorsal shield in the genera Uca, 
Cardisoma (and Gelasimus) really contains air, and is provided with a 
double system of blood-vessels ; the chitinous membrane which separates 
it from the visceral cavity can be moved in a lateral direction, and this 
movement is for expelling and renewing the air in the respiratory cavity.
