375] STUDIES ON GREG ARINES— WATSON 165' 



equatorial band of 12 to 15 long slender flexible filaments 32 to 35/i, long. 

 Nucleus spherical, with several karyosomes. 



Cysts spherical, 300/a in diameter, dehiscence by simple rupture, 

 spores cylindro-biconical, apices truncate, each face octagonal. Poles 

 armed with four spines each, two equatorial rows of spines, spores 2.5 

 by 5.1/x. 



Taken at Poitou and Avanton, France. Host: Hydrous sp. larva. 

 Habitat : Intestine.

[Figure 125] ' 



1892 Pogonites crinitus Leger 1892:149-5a 



1899 Cometoides crinitus Labbe 1899:29 



Cometoides: Sporonts solitary, very elongate. Maximum length 

 2000/1. Ratio length protomerite : total length : : 1 : 20 ; ratio width 

 protomerite : width deutomerite :: 1 : 1.3. Body shaped very simi- 

 larly to C. capitatus except that it is longer. Epimerite hemispherical, 

 flattened surface upward, armed with an equatorial ring of 6 or 8 long 

 slender flexible filaments 100/i, long. Endoplasm brown. Nucleus ellip- 

 soidal, with several karyosomes. 



Cysts spherical, 200 to 300/x in diameter. Spores cylindro-biconical; 

 spines at the poles and in two equatorial bands. 



Taken at Poitou and Vendee, France. Host: Hydrobius sp. larva.' 

 Habitat: Intestine. 



CORYCELLA ARMATA Leger 



[Figures 111, 112, 166] 



1892 Corycella armata Leger 1892:144-5 



CoryceUa : Sporonts solitary, 280 to 300/i long. Ratio length proto- 

 merite : total length : : 1 : 4 ; width protomerite : widtli deutome- 

 rite : : 1 : 0.9. Protomerite subglobular, constriction at septum, wider 

 in middle than deutomerite. Deutomerite widest at shoulder, tapering 

 thence to a sharp point. Endoplasm gray brown. Epimerite a large 

 globular papilla set upon a stout cylindrical collar which is two-thirds 

 as long as the protomerite itself, and armed with 8 strong short sharply 

 pointed recurved and backwardly directed hooks. Nucleus spherical,, 

 containing several karyosomes.
