Sporont 130-140/i in length, same general form as Pyxinoides balani 

 (Kolliker) Tr6gouboff, but with a long epimerite which penetrates to the 

 muscular layer. 



... la gr6garine possede un long epime'rite, qui traverse tout le tissu epithelial, s'accolle a 

 la galne musculaire sous-jacente et la suce. (Quoted by Tre'gouboff from Mawrodiadi.) 



Tregouboff adds: 



II est impossible de juger meme de la parent^ entre ces deux Gregarines 6tant donne" la deiec 

 tuosite 1 de la description qui d'ailleurs tient toute dans les quelques mots rite's plus haut.

Intestine and "ovarian appendage" of Cancer pagurus L. (Platycarcinus 

 (Lankester)). 



The first reference in literature to what may possibly have been a 

 gregarine was that of Redi in 1684, who found in the "vesicular ovariorum" 

 of Cancer paguri a parasite which Rudolphi (1810, 1819) refers to. as a 

 possible Distome or Monostome, and places in a list of "Vermes generis 

 dubii."
