During the summer of 1939 the movements of 237 tagged bullfrogs, Rana catesbeiana Shaw, were studied at the Edmund Niles Huyck Preserve, at Rensselaerville, Albany County, New York. These frogs were marked by locking numbered monel metal tags around the dentary bone. The results were reported by Raney (1940). Other studies on the growth of these bullfrogs in nature have been reported by Raney and Ingram (1940 and 1941). Additional returns on 22 individuals recaptured by Ingram in the summer of 1940, and 12 records obtained by Dr. Jean Piatt during 1941 serve as a basis for these notes.
