FIG. 2. — H in Fine structure of gametocytes in five species of Haemoproteus (Haemosporidia) from geckos and agamid lizards

FIG. 2. — H. edomensis (cont.); A, enlarged view (macrogametocyte?) showing mitochondria, some with electron-dense deposit (open arrow), Golgi-like organelle, vacuoles with phagosomal residue, trapezoid body and inclusions of unknown nature; B, apparently juvenile stage with nucleus containing two (split) nucleoli, some endoplasmic reticulum is filled with electron-dense material (larger arrow), and M3 is also visible (smaller arrows), tubular structures are enclosed within an endoplasmic reticulum cisterna; C, view of tubulies inside cisternae; D, macrogametocyte with dense ribosomal contents, a compact nucleus and a Golgi-like organelle; E-F, Haemoproteus mackerrasi; E, H. mackerrasi gametocyte inside an erythrocyte of Heteronota binoei; F, H. mackerrasi in gut contents of Culex fatigans induced to engorge Heteronota binoei. Note loose, undulating lamina remaining of M1 membrane (arrows). Abbreviations: cy, cytostome; e, vacuole with phagosomal residues; ec, inclusion with crystalline deposit (hemozoin); g, Golgi; m, mitochondria; n, nucleus; nu, nucleolus; o, osmiophilic bodies; rer, rough endoplasmic reticulum; t, tubular structures; tr, "trapezoid organelle"; v, vacuole. Scale bars: 1 µm.
