CEPEDEA BUGOSA (Carini) 



Figure 88 

 Opalina rugosa Carini, 1937. 



Host: Hyla nebulosa Spix, from Brazil. 



The body is generally straight or slightly bent, very slightly flat- 

 tened, and measures 270-320/i in length by 30-45/i in width. The 

 anterior end is a little larger than the posterior, which is blunt. 

 This Cepedea has been found only once or twice in spite of numerous 

 examinations. It presents on its surface a number of wrinkles, which 

 begin near the anterior end and extend almost to the posterior end. 

 In the anterior part the wrinkles have a linear longitudinal arrange- 

 ment, but as they proceed toward the posterior end they intertwine. 

 This wrinkled aspect is very characteristic of the species, seen in 

 living condition immediately after they are removed from the intestine. 

 It is not certain as yet whether this characteristic is a normal one. 

 (A restudy of this species is desirable.)

 Host: Rhacophorus maculatus Gray, from Nova Goa. 

 One very distinct characteristic of this species of Cepedea is the 

 alveolar appearance of the anterior end. The posterior end may be

either rounded or pointed. Length of body varies from 125n to 440/x. 

 There are numerous nuclei having a diameter of 4-5 fx.
