8S SPOROZOA. 



2. Tribe HETEROPOLARIDEA Bhatia, 1930 

 (including Family Choanosporid^ Dogiel). 



Intestinal or coelomic parasites usually of marine animals, 

 such as Polychsetes, Nemertines, Sipunculids, Echinoids, and 

 Ascidians. Sporocysts with dissimilar poles. The tribe com- 

 prises four famihes {vide Bhatia, 1930), of which only one is 

 known, so far, to be represented in India.

 Reichenow, 1929. 



{Syn. DoLiocYSTiD^ Labbe, 1899.) 



Body non-septate, distinguishable from the Monocystids by 

 the protoplasm in the anterior portion possessing finer 

 granules. A typical epimerite for attachment to the wall of 

 the gut of the host is present, but may be lost in fully grown 

 individuals. Syzygy does not occur. Sporocysts oval, with 

 a thickening at one pole. Parasites of marine Annelids.
