In the blood of lizards. The vermicules have a 

 peculiar shape (Fig. 72). Here also cyst forma- 

 tion has been described in the spleen by Labbe. 



8. H. mesnili. — In the blood of a tortoise, 

 Emys tectum (Fig. 73). 



Amoeboid forms, reniform, and vermicule 

 forms occur. Besides these, free merozoits, but 

 their origin is obscure. The form of the 

 vermicule is characteristic at one stage of its 

 development. 



g. H. lavevani. — In the blood of Indian 

 tortoises, Cryptopus granosus. Similar forms occur 

 to those of the last species. The vermicule is 

 characterized by a blunt hook- like appendage, 

 and the presence of two bright granules. 



The parasite is endoglobular in all its stages. 



10. H. higemina. — Discovered by Laveran 

 in the blood of blennies. A vermicule form occurs 

 free in the plasma. 



The endoglobular parasite divides by simple 

 binary fission. In fishes we also have H. delagei 

 in two species of ray and H. simondt in the sole. 



11. H. mauritanica. — In Testudo mauritanica. 

 Resembles H. stepanowi (Fig. 72). Two forms 

 occur : (i) very granular, smaller forms, with two 

 large refractile granules at each end ; (ii) larger, 

 uniformly pale forms. In stained specimens the 

 smaller forms appear oval or reniform, with a 

 nucleus transversely placed. The nucleus of the 

 red cell is displaced. The larger forms have at 

 one of the poles a pale blue mass, staining with 

 difficulty. Division forms are found in the liver. 



12. H. tunisiensis. — In Bufo maurit aniens. 

 (i) Vermicule form. The two limbs of the ver- 

 micule are equal ; the vermicule is encysted ;
