to the parasite is entirely similar to that of the host- cell and 

 the previous species. 



Marcel Leger (1913) and Laverallan and Marullaz (1914) 

 have previously described Leucocytozoons of a rounded form, 

 and interpreted them as different stages of the typical form. 

 De Mello and Afonso (1935 b) are, however, of the opinion that 

 they are definitely deaHng with two independent species, 

 of which the first one may be classified as a Leucocytozoon, 

 while the second has enough characters to constitute an 

 independent genus, to which the name of Marcel Leger should 

 be attached. As they have not given a definite name to the ' 

 species, but have simply described it as " type B," I have 

 for the present kept it in the genus Leucocytozoon and have 

 given the name melloi to the species.
