Sorry! Have another look.
You obviously noted that the infected red cells are not enlarged, however the

Malarial parasites not seen?
Sorry!
There are many parasites present in this field. Have another look
and pay particular attention to the size of the infected red cells.
Look out for delicate ring forms, marginal forms and the presence of
multiple parasites inside the same red cell.
