MUSGBAVR 



Intestinal cceca: These, two in number, rise from the bifurcation of 

 the oesophagus and run out in a zig-zag course on either side, very nearly 

 to the caudal end of the parasite. Sections through these organs show 

 what appears to be a primitive mucous membrane consisting of a base- 

 ment membrane with superimposed cells 



Genital pore: This is small and often indistinct. In 3 out of 5 speci- 

 mens it was to the left of the median line, close to the ventral acetabulum. 



Male organs: These are not very well developed; the testicles lie one 

 on each side of the median line, the one slightly more caudad than the 

 other, and both just posterior to the uterus, however; the latter organ 

 sometimes so overlaps one of the testicles as to render its detection dif- 

 ficult. The cirrus and cirrus pouch are absent. 



Female organs: The rather short, compact, closely coiled uterus may 

 lie on either side of the median line just caudad of the ventral acetabulum. 

 The ovary is distinct, branched, and usually almost opposite and slightly 

 posterior to the uterus. 



Excretory pore : This is prominent and situated at the caudal extremity. 



Vitellaria: These are numerous and well developed, covering almost 

 the entire parasite. Laurer's canal is present.
