Sporont 130-140/x in length, same general form as Pyxinoides halani 

 (Kolliker) Tr^gouboflf, but with a long epimerite which penetrates to the 

 muscular layer. 



... la gr^garine poss^de un long 6pim6rite, qui traverse tout le tissu 6pith61ial, s'accolle i 

 la galne musculaire sous-jacente et la suce. (Quoted by Tr^goubofiF from Mawrodiadi.) 



Tregoubofif adds: 

 D est impossible de juger mdme de la parents entre ces deux Gr^garines 6tant donne la d^fec- 

 tuosit6 de la description qui d'ailleurs tient toute dans les quelques mots cit6s 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."
