GEOGRAPHICAL RANGE OF ANIMALS.

partly fluviatile, and partly terrestrial ; while all Cepha- 

 lopoda are marine. Among Articulata, 1 the worms are 

 partly marine, partly fluviatile and partly terrestrial, 

 while many are internal parasites, living in the cavities or 

 in the organs of other animals ; the Crustacea are partly 

 marine and partly fluviatile, a few are terrestrial ; the In- 

 sects are mostly terrestrial or rather aerial, yet some are 

 marine, others fluviatile, and a large number of those 

 which, in their perfect state, live in the air, are terrestrial 

 or even aquatic during their earlier stages of growth. 

 Among Vertebrata 2 the Fishes are all aquatic, but partly 



1 The mode of distribution of free 

 and parasitic Worms, in different parts 

 of the world and in different animals, 

 may be ascertained from : GRUBE 

 (A. ED.), Die Familien der Anneliden, 

 Wiegman's Archiv, 1850. I mention 

 this paper in preference to any other 

 work, as it is the only complete list 

 of Annulata ; and though the local- 

 ities are not given, the references 

 may supply the deficiency. RUDOL-
