BERTABELLTA. 327 



or like a vacuole devoid of any central granule or a small 

 roundish body surrounded by a more or less strong membrane, 

 taking a chromatic stain, with a central nuclear granule. 

 The cytoplasm is stained blue or greyish-blue, often surrounded 

 by a white circular halo, without any granule at all or with 

 a central chromatic granule or the nuclear mass may be 

 located at the periphery attached to the membrane. The 

 infected red blood- corpuscle may have two or three of these 

 parasites, and does not show any alteration.

Fig. 162. — Bertarellia calotis de Mello & de Meyrelles. A, anaplasmoid ; 

 B, surrounded by a vacuole ; C, cytoplasm surrounded by 

 a strong membrane ; D, cytoplasm containing a central 

 chromatic granule ; E, cytoplasm with peripheral chromatic 

 mass ; F, with central and peripheral chromatic granules ; 

 G, chromatic granule showing budding. (After de Mello and 

 de Meyrelles.) 



Remarks. — Blood-smears fixed with Bouin's or Schaudinn's 

 fluid and stained with Heidenhain's iron-hsematoxylin are 

 said to have confirmed the structure as revealed by Romanow- 

 sky's stain, and have thrown fight on the process of division. 

 The chromatic granule or nucleus becomes enlarged and takes 

 a ring form. Later it becomes compact and gives origin 

 to a small bud, which protrudes to the exterior, becomes 

 covered by membrane and separated from the main ceU.
