"OPALINA SUDAFRICANA" Fantham 



Figure 122 



Host: Bufo regularis Reuss. 



Fantham's drawing and measurements, in microns, are given: 

 Body length 106 to 287.5, width 25 to 87. 



This seems either a narrow Opalina or an unusually flat Cepedea. 

 Narrow Opalinas are not known from the Eastern Hemisphere except 

 for less than half a dozen doubtful cases and except for 0. obtrigona, 

 which, with its hylid host, is a late immigrant from North America. 

 But Fantham's drawing appears more that of an Opalina than a 

 Cepedea. Restudy of fresh material would probably be worth while. 



OPALINA TRIANGULARIS Ghosh 



Figure 123 



Host: Bufo melanostictus Schneider. 



Ghosh's description (1918a), insufficient for certain identification, 

 is as follows: "Body flattened, leaf -like, twice as long as broad or less, 

 widest in the anterior body half; one side nearly straight, and the other 

 strongly convex giving the appearance of two curved sides meeting at 

 the widest part of the body; anterior end rounded and in the same 

 line with the straight side; posterior end tapering and rounded; 

 numerous nuclei. In the lower part of the intestine and upper part of 

 the rectum of Bufo melanostictus."
