filaments. Nucleus spherical, with a large karyosome and numerous 

 irregular chromatic granules. Cyst and spores unknown. 



Taken at Grenoble, France. Host: Chordeuma silvestre C. Koch 

 (C. sylvestre C. K.). Habitat: Intestine. 



Concerning the long chromatic filaments in the deutomerite, the 

 authors say (1904:374): 



"Sur la signification de ces singulieres formations, on ne peut qu'emettre 

 des hypotheses: ou bien ce sont des productions parasitaires, ce qui nous parait 

 peu probable, car toutes les formes globueuses en montrent a 1'exclusion des 

 formes allongees, ou bien ce sont des produits derives de 1'activitie cellulaire. 

 Tout en nous rattachant plus volontiers a cette maniere de voir, nous ne saurions 

 dire si ces produits prennent naissance dans le cytoplasme comme substances de 

 reserve ou de dechet comparables aux cristalloides deja signales chez certaines 

 Gregarines, ou bien s'ils derivent de la chromatine nucleare. Dans tout les cas, 

 nous ne croyons pas devoir les considerer comme des elements chromatiques ou 

 chromatides, destines a jouer un role important dans les phenomenes sexuels et 

 nous les regardons plutot comme des produits ergastoplasmiques." 



As heretofore, the size of the two dimorphants is considerable 

 (50%). The deutomerite of the smaller contains many long chromatic 

 filaments. At the same time, the deutomerite of the elongate form is 

 not devoid of scattered chromatin, which may be the broken remnants 

 of threads in a younger stage. Only two diplopods were parasitised, 

 one harbored many parasites; the other on the contrary very few. It 

 is possible, from the limited material at hand, that still longer and more 

 mature elongate forms may exist and bring up the percentage still 

 higher. 



For the views of the authors concerning its relationships compare 

 the paragraph quoted under Stenophora fontaria (page 60). 



From the data given, then, it is impossible to state with certitude 

 that the species are or are not the same. Dimensions correspond closely. 

 I have not included Crawley 's species here because of difference in shape 

 of the sporonts but have left it as a distinct species and placed it among 

 the Stenophoridae, the name now being Stenophora fontaria (Craw- 



ley).

No description or figure is given for this species. It is merely 

 mentioned as a parasite found in Craspedosoma legeri Brol. at Vizza- 

 nova, on the island of Corsica.
