SPOEOZOA. 



consisting of many chromatinic rods irregularly connected 

 together ; pigment granules smaller, more or less scattered 

 through the cytoplasm. Female gametocytes stain a compact 

 and deep blue, have a large nucleus, and the pigment granules 

 are larger. Infection very scanty. Infected red cells hyper- 

 trophied. 



Habitat. — Blood of the moor-hen, Gallinula chloropus Linn. : 

 PoETUGUESB India, lake of CaramboHm.

'fPlasmodiutn herodiadis, de Mello, 1935 a, p. 351, pi. xlii, fig. 1 ; 

 de Mello, 1931 a, p. 98. 



Ring form with a granular or rod-like chromatinic dot. 

 Older trophozoites pyriform or rounded, with irregularly 

 scattered brownish- black pigment. Rosettes mth five to 

 ten chromatinic bodies. Male gametocytes somewhat oval, 

 with a larger, irregular nucleus. Female gametocytes roundish, 

 with a round nucleus. Infection not very heavy. Parasitized 

 red cells not altered.

 pyriform or rounded trophozoites ; D, schizont ; E, male 

 gametocyte ; F, female gametocyte. (After de Mello.) 



Remarks. — This form is said to be distinguishable from 

 Hsemoproteus herodiadis, found in the same host, by the 

 nucleus being stained a vivid red colour in the former and 

 a pale rose colour in the latter. 



Habitat. — Blood of the heron, Egretta intermedia intermedia 

 Wagler : Poetuguese India, lake of Carambolim. 



216. Proteosoma heroni (Basu). 



■f Plasmodium heroni, Basu, 1938, p. 244. 



Remarks — -Morphological description of the species has 

 not yet been published. Infection is easily transmitted 

 from one paddy-bird to another by blood inoculation, and the 

 disease set up is severe. 



Habitat. — Blood of the paddy-bird commonly known as 

 " pond heron " : Bengal, Calcutta.
