ZSCHOKKELLA. 339 



(disporoblast ?) contained in one instance 10 nuclei, but 

 it seems likely that 12 is the full number of nuclei in the 

 disporoblast, as the final sporoblasts into which this divides 

 appear to contain usually 6 nuclei. Of the 6 nuclei of the 

 sporoblast 2 go to form the valves of the sheath, 2 attach 

 themselves to the polar capsules, and 2 remain in the sporo- 

 plasm. The two last-mentioned nuclei may fuse into one. 

 In the sporoplasm two large vacuoles are often seen, one near 

 each polar capsule. Both ends of a spore taper to a blunt 

 point and the spore-coat is markedly striated. 



Dimensions. — Spores average 16 ju, in length by 5 ju, in breadth. 



Remarks. — ^The description is based on sections of the kidney 

 of the host prepared by J. Percival Mackie in the Bombay 

 Bacteriological Laboratory. 



Habitat. — Kjdney of the tortoise, Trionyx gangeticus Cuvier : 

 Bombay, Bombay.

Spore semicircular in front view ; ellipsoidal in profile ; 

 ends pointed. Sutural line much curved. Polar capsules 

 large and spherical ; polar filaments long and fine. Mono- 

 sporous, disporous or polysporous. Typically coelozoic 

 parasites of fresh- and salt-water Fish.
