SMITH The tadpoles of this species have been described by Bragg (Copeia, 1936: 14-20, figs. 1-13; Amer. Midl. Nat., 18:273-284, figs. 1-5, 1937). The drawings and descriptions of the mouthparts, however, appear to have been taken from dried, or immature, or transforming individuals, for they do not agree among themselves nor do they agree with larvae obtained in the field and now in the Museum of Natural History of the University of Kansas.
