BRITISH FEESHWATEE, EHIZOPODA. 



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 /a (Penard). 



If large empty tests of the globulus type may be 

 assumed to be those of Phryganella nidulus Penard, 

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

 7ium-bogs in England, "Wales, and Scotland, to be a 

 British species. But, for the reason already given. 



Fig. 77. — Phryganelli 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 — Avhich 

 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.' 



3. Phryganella paradoxa Penard.
