CEPEDEA (?) 

 FiGUHB 81 



Host: Bana crassa Jerdon. 



In a rather young tadpole of this frog, 43 mm. long, body 13.5 mm. 

 and hind legs 2 mm. long, collected in southern India, were opalinid 

 larvae that, of course, could not be identified without a larger series

of material. They seem to be Cepedea, though there is a possibility 

 that they are Opalina in a Cepedea stage of the life history. 



Measurements, in microns: Body length 77, width 16; nuclei 3.4 

 by 3.2, 4.7 by 2.6, 3.8 by 3.8. 



CEPEDEA species (7) 



Figure 82 



Host: Eleutherodadylus guentheri (Steindachner), from Angra dos 

 Reis, State of Rio de Janeiro, Brazil. 



In tadpoles of this host, 46 mm. long, of which 17 mm. is length of 

 body and the rest taU, there are very slender larvae of Cepedea, which

cannot, from the material in hand, be assigned to any species. Note 

 that, as is often the case in multinucleate opalinids, the nuclei are 

 larger in the younger forms.
