 the level of the cloaca; 1st pair post-anal ventral papillae just 

 behind cloaca, last pair 85 jx from caudal extremity. Spicules 

 unequal : right pointed and thick, 150 /a long ; left slender, 260 /x 

 long.

 of body-length. Bursa 1-4 mm. long ; 2 pre-anal and 2 post-anal

From Gedoelst's description this species appears to be the same 

 as PJi. paradoxa v. Linst. I have examined Phjsalopteia from 

 the same host, and these have been found to belong to von Linstow's 

 species, and consequent!}' Gedoelst's species must be relegated to a 

 synonym of Ph. paradoxa.
