Fixed tissues from 13 armadillos and cell cultures from two were examined for the presence of sex chromatin. Barr bodies were easily recognizable in smooth and cardiac muscle tissue of adult animals and in loose connective tissue of the embryos. Nervous tissue proved unsuitable for sexing both in young and adult armadillos. Cultured cells in vitro were also examined and showed prominent nuclear sex chromatin in the female animals. These results are in accordance with Benirschke's earlier findings in these animals.
