Nordrichon 1950 Hyla labialis Nov. 15 Bogota, 850ft., Cundinamarca, Colombia, S.A. are females. Is this an indication of a beginning breeding period, with an almost all-male chorus at first? Apparent absence of eggs and tails would seem to bear this out, as would the finding of one of the four females in amplexus. The male has an enlarged thumb, a darker, wrinkled, throat skin, and a belly coloration lacking dark, reticulate, punctate spots.
