pressed chiefly in the anterior half, A front view shows a deutomerite 

 as broad as it is high. The nucleus is large, spherical or slightly ovoidal 

 and contains one large karyosome. The parasite is characterized then by 

 its compression, the invagination of its protomerite and by its inter- or 

 intra-cellular location (the authors are not sure which). 



Taken in Provence, France, and on the island of Corsica. Hosts: 

 Blaniulus hirsutus BroL, Brachyiuhis superus Latzel, Brachyiulus pusil 

 lus lusitanus Verh. Habitat : Intestine. 



STENOPHORA NEMATOIDES Leger and Duboscq 



[Figures 14 and 15] 



1903 Stenophora nematoides Leger and Duboscq 1903a :335-7 



Stenophora: Sporonts solitary, elongate. Average length 170/x., 

 maximum length BOOju.. Width not given. Ratio length protomerite : 

 total length : : 1 : 10 ; width protomerite : width deutomerite : : 1 

 : 3. Protomerite cylindrical, slighly dilated a little anterior to septum. 

 Twice as long as wide, dome shaped at apex ; constriction at septum. Deu- 

 tomerite normally with constriction at end of anterior third, or half; 

 above this point considerably dilated, especially in posterior portion. 

 Posterior half or two thirds of deutomerite, i. e., part below constriction, 

 cylindrical, ending in a broadly rounded or somewhat truncate extremity. 

 The largest sporonts tvithout the peculiar dilated portion of the deutome- 

 rite ; nematoid in shape, long, slender, cylindrical, often slightly curved 

 and with a body as much as seventeen times as long as to protomerite 

 (170 : 10), and not more than 7yu, wide throughout. Endocyte granules 

 fine, homogeneous except in anterior end of protomerite where deeply 

 staining chromatic granules are accumulated. Nucleus large and ovoidal, 

 the long axis parallel to the long axis of the body. One large karyosome. 

 Epimerite a large subglobular hyaline body. Cyst and spores unknown. 



Taken at Bastia, Corsica. Host: Strongylosomum italicum Latzel. 

 Habitat : Intestine. 



The authors' conclusion concerning this species is as follows: 



"Bien que nous ne connaissions pas revolution complete de cette Gregarine, 

 nous avons la conviction qu'il s'agit d'une espece voisine du Stenophora iuli, car 

 a part la forme generale nematoide qui est ici tres caracteristique de I'espece, toutes 

 le autres particularities structurales (forme du protomerite, caractere du noyeau, 

 presence de grains chromatoides accumules surtout dans le protomerite, etc.) se 

 retrouvent aussi chez les autres especes du genre Stenophora, lequel d'ailleurs est 

 special aux Diplopodes."
