OPALINA CHENI Nie 



Figure 117 



Host: Kaloula borealis Barbour, from Nanking, China. 



The body of Opalina cheni is roughly triangular, the base of the 

 triangle being anterior and the apex posterior. The anterior border, 

 however, is not straight but slightly curved, and it often inclines more 

 to one side of the body than to the other. There are several longi- 

 tudinal folds or ridges, which a,re gradually diminished in size as they 

 extend from the a,nterior border to the posterior end. The posterior 

 end is distinctly tapering and pointed at the extremity.
