In the young condition the macrogamete is a small, naked, 

 granular sphere, provided with a nucleus and situated in a host- 

 cell. The sphere grows till it reaches a diameter of 20-22 /*. 

 After undergoing syngamy it secretes a double membrane 

 round itself. The granular mass contracts and divides 

 into four sporoblasts. Oocyst spherical ; contains four oval

sporocysts without any residuum. Sporocyst oval ; con- 

 tains two comma-shaped sporozoites, the larger ends of which 

 are situated at opposite poles, and there is a small mass of 

 sporocystal residuum. Schizogony was found in some cells, 

 resulting in a large number of merozoites. 



Remarks. — It is rare to find a Coccidium in an organ from 

 which there is no exit for the ripe oocysts. Simond beheved 

 that the parasite must be occurring also in other organs con- 

 nected with the intestine, but could not find them there. 



Habitat. — Spleen of the gharial, Gavialis gangeticus (GmeHn), 

 of the River Ganges.
