58 ILLINOIS BIOLOGICAL MONOGRAPHS [268 



Width nearly the same throughout and ending in a blunt rounded poste- 

 rior extremity. Endocyte not described. Nucleus ellipsoidal, 1.7 times 

 as long as wide. Cysts spherical, 250/u. in diameter. Spores regularly 

 ovoidal, epispore present. Equatorial line on spores. 



Taken at Turin, Italy, and in Dauphine, France. Hosts: Julus 

 mediterraneus Latzel (Schizophyllum mediterraneum Latz.) ; Julus bo- 

 leti C. Koch (Julus londinensis Mein.) ; Julus fallax Mein. (Julus albipes 

 C. Koch). 



The authors described a parasite found in the same host as that 

 upon which Schneider based his observations in his discovery of Grega- 

 rina juli (Frantzius). The species named by Schneider as the host of his 

 parasites was Julus terrestris (Linnaeus) Porat but Leger and Duboscq 

 observed that this species does not occur in France (1904:363). 



"Nous decrirons d'abord Stenophora iuli (Frantzius) Schneider, qui nous a 

 fourni de bons documents pour 1'etude du developpement des Stenophorides, et 

 dont il importe de preciser la diagnose. Nous entendons par Stenophora iuli 

 (Frantz.) Schneider le parasite de Schizophyllum sabulosum L. qui correspond a 

 la description de Schneider. Cet auteur trouvait aussi Stenophora iuli dans lulus 

 terrestris, mais lulus terrestris L. n'est pas une determination. Depuis un siecle, 

 les anastomistes appellent de ce nom tous les lules qui sont de coleur noire, et le 

 veritable lulus terrestris (Linne) Porat ne parait pas exister en France. . . Et 

 en effet, nous voyons dans un certain nombre d'lules, une Gregarine bien voisine 

 du parasite de Schisophyllum sabulosum L. Citons notamment parmi les hotes 

 de Stenophora iuli, Schizophyllum mediterraneum Latz. de la Tourraine, lulus 

 londinensis Mein. de la Tourraine, lulus albipes C. K. du Dauphine." 



These authors base their observations on the parasites found chiefly 

 in Julus albipes. In Julus sabulosus the gregarine attains a length of 

 450/* ; in J. fallax Mein. and J. boleti C. K. of 300,*. Besides the elon- 

 gate form, they mention a globular form nearly as wide as long, and 

 reaching 130/* in length. They do not illustrate this form. The elongate 

 sporont, only, is figured. The authors do not describe the shape of the 

 various parts and make no comparison of their form with the classic 

 S. juli, basing their identification rather on a similarity of hosts than of 

 parasites.
