 larger) ; inner denticulate border reduced and interrupted in 

 places. 



Muscular oesophagus very short. (Esophagus l/6th in male,

 muscular oesophagus.

Male bursa lanceolate ; 4 pairs circumcloacal stalked papillae. 

 Thirteen ventral papillae ; of these, 3 in front of anus, the lateral 2

 1*44 mm. long; spicules unequal, right 370 /x, left 2'1 mm. long. 

 Arrangement of bursal papillae as in Ph. affinis. Vulva divides 

 body into ratio of 1 : 4. Two uteri. Eggs 56-63 x 40-44 /x. 



Host : Chamceleon gracilis. Stomach. Belgian Congo. 



I agree with Irwin-Smith (1922) that this species is the 

 same as Ph. lejAoso'ina (Gervais), Seurat, 1917. The close similarity 

 between Gedoelst's and Seurat's descriptions is very striking. 

 The slight differences in the lengths of the spicules, length of 

 oesophagus, and position of the vulva can verj^ well be accounted 

 for as individual varia,tions.
