GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. 15Q9 



I. ANOMOURA. 



XVI. The Anomoura are nearly equally divided between the 

 torrid and temperate zones, there being hardly one-tenth more torrid 

 than cold-water species. Only fifteen species out of two 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, and part of the Paguridea, the species hardly extend beyond 

 the warmer half of the temperate zone. There are but six known 

 frigid species, and these are of the two last-mentioned groups. 



XVII. The torrid zone and temperate zone sections of the Ano- 

 moura, are as follows ; the frigid zone species being here added to the 

 temperate.
