 of a line). Male unknown.

 bilabiate ; lips lateral, prominent. Caudal extremity incurved,

Yulva just behind middle of body ; it divides body into ratio 

 23:21. Eggs 39 x 26 yn. 



Host : Francolinus adspersus. Intestine. S. W. Africa.

 From the description I am not able to place it in any known 

 genus, and consequently^ list it under Sp. Inq.
