Monocyte is singular. Monocytes is plural.
Most likely a metamyelocyte or monocyte.. Of course, "Kidney-bean-shaped" is a pretty broad description, and many cells could have that vague appearance on a slide. Most commonly that description is associated with metamyelocytes, which are immature Granulocytes (Segs, Eos, and Basos). However, if the question was in reference to a fully matured WBC, it likely would be a monocyte. If you are trying to tell them apart, remember monocytes (like lymphs) are not Granulocytes, and should not have cytoplasmic granules. A meta will (usually) have granules.
