The parasite occurs in two forms, elongate or shorter and 

 stumpy. In the extra-corpuscular form it is gregariniform 

 and without a capsule. Cytostome stains blue with Leishman's 

 stain, and the nucleus is elongate, rectangular, generally 

 compact, rarely vesicular, occupying a large part of the 

 parasite and situated near one or other extremity. The 

 intra -corpuscular stage has the same appearance, but possesses 

 a large clear capsule containing sometimes one or two vacuoles 

 in the centre. The short and stumpy form is equally broad 

 at both poles, and has a less extensive capsule.

 & Noronha. A—D, intra-corpuscular forms ; E, free form. 

 (After de Mello and others.) 



Remarks. — The parasite is very common, 50 per cent, of 

 the lizards examined being infected. It could not be deter- 

 mined whether schizogony takes place in the blood or in the 

 internal organs. The short stumpy form was originally 

 described as a separate species under the name of H. proencse, 

 but de Mello (1934 a) has amalgamated the two. 



Habitat. — Blood of Hemidactylus hrooki Gray : Poettjguese 

 India, Nova Goa.
