The Tadpoles of Bufo cognatus Say

The tadpoles of this species have been described by Bragg. 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. At hand are two series of tadpoles of this species; one series was collected July 2, 1938, 1. 5 miles east of Meade County State Park, Kansas, and the other lacks data. The second lot contains numerous sizes of tadpoles from 14 mm. to 31 mm. , and several transforming specimens which clearly possess the pattern so typical of this species.
