its base and tapers to a fine point; the right spicule is stout, 

 495 n long and 50 fi broad at its base, and also terminates in a 

 fine point. 



Host: Erinaceus eurojjceus. Stomach. Europe.

My observations on this species differ in many respects from

 the other two, whereas Seurat finds this papilla to be veiy 

 small. 



With regard to the post-anal ventral papillae, the third pair is 

 stalked in Seurat's material and sessile in mine. 



Further, the spicules of his specimens difter from those of 

 mine both in length and in shape ; in his material the right and
