■fLeucocytozoon coraciae benghalensis, de Mello & Afonso, 1935 b, 

 pp. 71-2, pi. ii ; de Mello, 1937 a, p. 105. 



Form of the adult gametocyte ovoid, included in a fusiform 

 cell. Cytoplasm finely alveolar stains blue with Romanowsky 

 stains, but lighter than in i^. melloi. Ratio of length to breadth is 

 5 to 2 in intracellular forms and 7 to 4 in free forms. Nucleus

ovoid or bean-shaped, central or subcentral. Sexual dimor- 

 phism is recognizable in the structure of the nucleus as stained 

 by iron hsematoxyhn. The nucleus of the female gametocyte 

 is small, with a karyosome and a centriole or only with centriole. 

 The nucleus of the male gametocyte is much larger, often oval, 

 elongated, or even bean-shaped, filled with granules, but without 

 a centriole. 



Remarks. — No young forms or schizogony stages were 

 recognized. Specimens of this species were far more abundant 

 (in the ratio of 7 to 1) than those of L. melloi described from 

 the same host. 



The poles of the fusiform host-cell are stained greyish-blue 

 by Romanowsky stains, and stained Hghtly by Heidenhain's iron
