cylindrical, tapering slightly and ending bluntly. Nucleus large, spheri- 

 cal. Cyst and spores not known. 



Taken on the island of Corsica. Host : Scolopendra oraniensis lusi- 

 tanica Verh. Habitat: Intestine. 



This species differs from N. giardi type only in that a) it attains but 

 half the length of the former, b) the confluent lobes of the protomerite 

 are upturned further in the adult, and c) the lobes of the protomerite 

 are shorter and blunter.

1911 Nina indicia Merton 1911 :119-26 



Nina : Sporonts solitary, elongate. Length 500/i - 1500/a. Width 

 not given. Ratio length protomerite : total length : : 1 : 20 ; width pro- 

 tomerite : width deutomerite : : 4 : 1. Protomerite bilaterally symmetri- 

 cal, low and very broad, eight times as wide as high, formed of two long 

 sinuous narrow plates separated at one end for a very short distance. 

 Each bearing a narrow ridge at the upper margin set on both sides with 

 short sharp teeth. The two ridges never confluent but nearly parallel 

 throughout their length. Deutomerite elongate, irregularly cylindrical, 

 dilated a short distance below the septum and tapering from the middle 

 to a long slender and pointed posterior extremity. Endocyte dense in 

 deutomerite, much less dense in protomerite. A deeply staining vesicle 

 at one end of protomerite. Nucleus spherical with chromatin arranged 

 in one convoluted band. Cyst and spores not described. 



Taken at Heidelberg, Germany. Host: Scolopendra suhspinipes 

 Leach. Habitat : Intestine.

Echinomera : Sporonts solitary, obese. Measurements not given 

 in the literature. Ratio length protomerite : :total length : : 1 : 7 to 

 1 : 11 ; width protomerite : :width deutomerite : : 1 : 2 to 1 : 2.4. Pro- 

 tomerite broad, flattened, surmounted by a persistent epimerite in the 

 form of an irregular asymmetrical cone as broad at its base as the proto-
