CEPHALOIDOPHORA COMMUNIS Mawrodiadi Type Species 



[Figure 77] 



1890-1 No name Solger 1890-1:233 



1899 Gregarinasp. Labbe 



1903 Gregarina sp. Minchin 



1908 Cephaloidophora communis Mawrodiadi 



1911 Cephaloidophora communis Sokolow 1911:286 



1912 Cephaloidophora communis Mercier 1912a: xli 

 1912 Cephaloidophora communis Tregouboff 1912: liii 



Sporonts 65-80/* in length. Protomerite and deutomerite rounded. 

 Associations in pairs, the primite the larger. Intracellular trophozoites 

 found in intestinal epithelium and hepatic cells. A thickened hyalin 

 crescentic area at apex of protomerite corresponding to a rudimentary 

 epimerite. Ratio LP : TL :: 1 : 4; WP : WD : 1 : 1.5. Cysts spheri- 

 cal. Spores with eight sporozoites, ovoidal, 4.5 by 4/z, with faint equator- 

 ial line. Sporozoites subspherical 



Hosts: Balanus improvisus Darw.; B. improvisus gryphica Munter; 

 B. tintinnabulum communis L.; B. perforans Brug.; B. amphitrite Darw.; B. 

 eburneus Gould. 



Habitat: Intestine and caeca. 



Taken at Odessa, Cette, France, etc. 



The original description is in Russian and is not available. The above 

 data is taken from Sokolow's translation and from Tregouboff's new 

 observations upon Jive material. 



Buddington (1910:470) gives a brief description of an unnamed species 

 found in Balanus eburneus Gould, presumably at Woods Hole, Mass., 

 merely stating the animal to be a polycystid gregarine of rapid movement, 

 with a nucleus having five karyosomes and chromidial bodies in the 

 protomerite. It is quite probable that he found the above species.
