1874 "Gregarinae" Moseley 1874: 762 



1899 Gregarina sp. Labbe 1899: 37 



1903 Gregarina sp. Minchin 1903: 331 



The only data which exist concerning this parasite are the following: 



Some very small encysted Gregarinae were found in the stomachs of all the specimens 

 examined. 



Host: Peripatus capensis Grube. 



Taken in Equatorial Africa. 



One might wish that more data existed concerning the type of gregarine 

 which inhabit this intermediate host. Theoretically, it should be a form 

 intermediate between the family Polyrhabdinidae and the true Cephaline 

 Gregarines.
