BRITISH FRESHWATER RHIZOPODA. 



similar to those of P. acropodia, from broad lobate 

 expansions of ectoplasm, to narrow, digitate, more or 

 less pointed ones, extending radially in all directions. 



Dimensions : Average diameter 180-190 p (Penard). 



If large empty tests of the globulus type may be 

 assumed to be those of Phryganetta nidulus Penard, 

 we may claim this, from examples met with in Sphag- 

 num-bogs in England, Wales, and Scotland, to be a 

 British species. But, for the reason already given, 



FIG. 77. Phryganell i nidulus. After Penard, loc. cit. (slightly re- 

 duced). 1, upper view; 2, oral view; 3, three-quarter view ; 4, one 

 of the nuclei, x about 140 ; the nucleus much more highly. 



without an examination of the living organism which 

 is rarely met with it is impossible to pronounce with 

 certainty. Tests from near Ingleton, West Yorkshire, 

 from various localities in Cheshire, and from North 

 Wales answer to Penard's description and figures in 

 ' Faune Rhiz. Leman.'
