METAMERA SCHUBERGI Duke Type Species 

 [Figures 131, 132, and 133] 



1910 Metatnera schubergi Duke 1910: 261 

 1913 Metatnera schubergi Ellis 1913: 285 



Sporonts 150 by 45/1. Deutomerite with one to three septa posterior 

 to the nucleus. Cysts spherical, spores ovoidal 9 by 7/i. 



Epimerite subconical, apex eccentric with corona of numerous branched 

 digitiform processes. 



Taken at Heidelberg and Cambridge, Eng, 



Intestine of Glossosiphonia complanata and Hemidepsis marginata. 



I am not ready to assign this species to a position in the family Dactylo- 

 phoridae, as placed by the author. The method of cyst-dehiscence is differ- 

 ent from the type for that family and the spores are not elongate cylindrical. 

 The host is so far removed from the Chilopoda (to which the named family 

 is confined) that I feel certain the species belongs in a group as yet unde- 

 scribed. When more similar species shall have been described its position 

 can the better be determined. 



METAMERA sp. Ellis 



1913 Metatnera sp.? Ellis 1913:285,287 



Host: Clepsitie elotigata. 



Species of Uncertain Position 



TAENIOCYSTIS LEGERI Cognetti de Martiis 

 [Figure 130] 



1911 Taeniocystis legeri Cognetti de Martiis 1911:247 



Polycystid gregarine, solitary, protomerite and deutomerite segmented 

 by 16 to 19 septa. 700 to I6OO/1 in length. 



Epimerite, cyst, and spores unknown. 



Taken at Moramanga, Madagascar. 



Host: Kytiotus Pittarelli (oligochaete). Coelomic. 



The "protomerite" is divided into three segments, which is unique. 

 The parasite is coelomic rather than intestinal, as are all other polycystid 

 gregarines. The epimerite is unknown. For these reasons it is not 

 placed with the type for the genus. The single nucleus seems to place it 

 with the Protozoa; otherwise it might be a haplosporidian.
