Sporonts 65-80/i in length. 

 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/i, with faint equator- 

 ial line. Sporozoites subspherical 



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

 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 live 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.
