possessed by the animal these differences are of so shght a character 

 as to be negligible and the difference in shape between my examples 

 and the figure given by Cort of Sch. japonicum is of no importance 

 in so protean an animal ; the differentiation of the cephalic gland 

 cells in the Indian form into coarsely-granular and finely-granular 

 cells is a physiological rather than a morphological difference. 



The occurrence of animal-infecting forms of Schistosome in 

 India has been known since the researches of Montgomery ' — and 

 the finding of a cercaria, stated to be that of Schistosoma spind- 

 alis, Montgomery, has been recorded by Glen lyiston and Soparkar,* 

 but as no details of structure are given by these authors it is im- 

 possible to compare their specimens with the present form. 



The final test of the identity of this form with that of Schis- 

 tosoma japonicum lies in the similarity or otherwise of the adults 

 and experiments are now being carried out to obtain the fully-grown 

 sexual stage of this parasite.
