ANTHORHYNCHUS SOPHIAE (Schneider) Labb6 Type Species 



[Figures 58, 108] 



Sporonts solitary, obese. Maximum length 2 mm. Width protomerite 

 330m, deutomerite 600^. Ratio LP:TL::1:11 (without epimerite); 

 WP:WD::1.2. Protomerite small, flattened, three times as wide as 

 high, no constriction at septum. Deutomerite conoidal, widest just 

 below septum, tapering thence and ending in a broad blunt extremity. 

 Epimerite a series of short blunt digitiform processes united laterally 

 and curved inward to form a broad flattened corona. Epimerite 200/x high. 

 Nucleus not described. 



Spores 6.9 by 4.6/*, broad, biconical, extruded in chains laterally 

 attached. 



Intestine of Phalangium opilio. 



Taken at Poitiers, France. 



Genus SCIADOPHORA Leger 1897: 36, emend Labbe 1899: 18 



Epimerite a large flattened centrally indented papilla with a crenulate 

 periphery. Protomerite with numerous backwardly directed leaf-like 

 processes arranged vertically, each sharply pointed at its posterior extrem- 

 ity. 



SCIADOPHORA PHALANGII (Leger) Labbe Type Species 

 [Figures 59, 60, 62, and 106] 



Sporonts solitary, very elongate, up to 2.5 mm., one of the largest 

 known species. Width not given. Ratio LP : TL :: 1 : 12; WP : WD:: 

 1.3:1. Protomerite broadly conical at apex with 15 or 16 vertical 

 lamillar plates starting below the apical cone recurving backward and 

 terminating in sharp hooks. The whole bears a resemblance to an um- 

 brella. Deep constriction at septum. Deutomerite widest at shoulder, 

 tapering to a very long slender acuminate extremity. Epimerite a large
