Heterophil showing chromophobic bands across 



the nuclear lobes. 



Erythroplastid. 



Late polychromatic erythrocytes. 



Erythrocytes in which the distorted shapes may 



have been acquired during the making of the smear. 



A "typical" erythrocyte. 



Erythrocyte with an elongated, dense nucleus. 



Erythrocyte with nucleus eccentrically placed.

 and almost round. 



11 Erythrocyte with nucleus indented at one end. 



12 Erythrocyte with nucleus indented on one side. 



13 Erythrocyte with a pyknotic nucleus. 



14 Erythrocyte nucleus with a protrusion.
