forms also contain a nucleus which may be compact or frag- 

 mented. Certain large forms are schizonts. 



Dimensions. — Vermicular form, length 12-15^ ; schizonts, 

 20 ju, in diameter.

Fig. 48. — Heemogregarina hankini Simond. A, large form with com- 

 pact nucleus ; B, parasite with two nuclei, due to two 

 parasites adhering together ; C, oval form, with a number 

 of nuclei arranged on the periphery ; D, yoimg parasite 

 with dispersed nucleus ; E, larger form with dispersed 

 nucleus (n, nucleus of corpuscle ; p, parasite). (After 

 Simond.) 



Remarks. — According to Simond two forms of the parasite 

 are met with, viz., vermicular and oval. In the young 

 vermicular form the nucleus is compact or fragmented into 

 a number of granules arranged in each limb of the parasite. 

 The parasite is always doubled upon itself, the two limbs being 

 parallel and sometimes in contact with one another. In the 

 oval form also the nucleus may be compact or fragmented. 

 Cells with incompletely developed merozoites were observed in 

 the lung. These schizonts were spherical, and contained 

 30 to 40 fusiform merozoites without any residue of segmenta- 

 tion. If it be confirmed that schizogony takes place in the 

 lung, the species will have to be transferred to the genus 

 Hepatozoon. 



Habitat. — Blood of Gavialis gangeticus Gmelin : United 

 Provinces, Jumna River ; Crocodilus porosus Schneider (?) : 

 India (exact locality not cited) ; and Crocodilus porosus 

 Schneider : Ceylon, Daduganoya, Veyangoda.
