Cells without nucleus = Bacteria + the Archaea without nuclei, in other words, cellular life minus Eucarya, in still more words, "protists" (often called Protista, inapropriately because this is a paraphyletic grouping - a branch of the tree of life with bits chopped off.

Red blood cells or erythrocytes.
"Erythrocytes in mammals are anucleate when mature, meaning that they don't have a cell nucleus and thus no DNA. In comparison, the erythrocytes of nearly all other vertebrates have nuclei; the only known exception is salamanders of the Batrachoseps genus. Mammalian erythrocytes also lose their other organelles including their mitochondria and produce energy by fermentation, via glycolysis of glucose followed by lactic acid production."
