OPALINID CILIATE INFUSORIANS METCALF

Cepedea (fig. 137).— The genus Cepedea can, perhaps, be divided 

 mto several groups, but few of these are sharply demarcated and the 

 divisions are of little interest. As given, they express little more 

 than the author's impressions and these in some cases vague and 

 uncertain. 



Subgeneric Group I 



In group I Metcalf (1923a) included only Bezzenberger's C. lan- 

 ceolata, in Rana, "Asia." 



Subgeneric Group II (fig. 1S8) 



Group II is a large group of eastern distribution, except for four 

 species and one subspecies from tropical and subtropical America. 

 I see no reason except their western habitat for separating the latter.
