THE CHAEACTERS OF THE DEEP-SEA FAUNA 85 



Taking the fauna as a whole, Moseley regarded it 

 as similar in some respects to the flora of the high 

 mountains. Some forms are dwarfed in size, such as 

 the species of Radiolaria, Cerianthus, some of the 

 Cephalopods, &c., while others are very much larger 

 than their shallow-water allies, such as the Pycno- 

 gonids, nearly all the Crustacea, Alcyonarians (as 

 regards the size of the polvpes), Siphonophora, and 

 manv others.
