22 BUITISH FRESHWATER RHIZOPODA. 



Ireland.— Clare Island, Mayo ; Inishbofin, Galway. 



When two spines are present they are inclined in 

 opposite directions (fig. llbh), when there is only one 

 spine it may be inclined (fig. 115 c), or, as is generally 

 the case, bent near its base so as to lie in the line of 

 the longitudinal axis of the test (tig. 115 a); the scales 

 which furnish the spines are a little distance away 

 from the apex and are not terminal scales as in 

 E. mucronata Leidy. 



From E. cristata var. major the test differs in 

 possessing a more acute apex and in the possession 

 of the characteristic spines. 



It can hardly be confused with E. mucronata Leidy, 

 which has a quite differently shaped test and an apical 

 spine.
