39. Hirmocystis (?) parapeneopsisi Setna & Bhatia. (Fig. 40.) 



'\Hirmocystis (?) parapeneopsisi, Setna & Bhatia, 1934, pp. 35-8, 

 figs. 1-11. 



Sporonts stoutly built, forming early syzygies. Associations 

 of two or three individuals in linear chains, or unique associa- 

 tions of two primites with a single satellite. Ratio of length 

 of protomerite to total length as 1 : 5-7 ; width of proto- 

 merite to width of deutomerite as 1 : 1-4. Epimerite a small 

 rounded knob. Protomerite hemispherical or flattened, 

 constricted at the septum ; deutomerite cyHndrical or barrel- 

 shaped, broadly rounded or flattened behind. Satellite 

 longer than the primite, second satelhte longer than the first. 

 Nucleus spherical, with a single karyosome. Gametocysts

 B, chain of two individuals ; C, two primites followed by a 

 single satellite ; D, single satellite torn asunder by two 

 primites pulling apart. (After Setna and Bhatia.) 



spherical or slightly eUiptical. Dehiscence of gametocysts 

 and sporocysts not observed. 



Dimensions. — Associations, maximum length 425/x,, maxi- 

 mum width 44 /x ; free sporonts 40-80 /x. 



Remarks. — A few cases were met with in this species of 

 the rare type of association in which two primites were 

 followed by a single satellite. The primites were posteriorly 

 rounded off and fitted into curved depressions in the anterior 

 margin of the satellite. In other cases two satelhtes ran into 

 one another and showed partial or complete fusion, the deuto- 

 merite containing one or two nuclei. 



The form resembles Hirmocystis in as much as the sporonts 

 form associations of two or more, and the epimerite is small,
