Abstract
A description of 2 cases of hermaphro-ditism in the frog, the entire animal in 1 case and the urinogenital organs only in the other. Both possess testes and vasa efferentia, with one or more oviducts. Pigmented lobes which are attached to the testes are considered as ovarian tissue, though no histological examination seems to have been made. It is concluded that these specimens were originally [female][female] whose ovaries have degenerated and testes formed, though no evidence is given to support the conclusion. The question of sex determination is discussed and it is concluded that evidence is accumulating that sex is not determined by sex chromosomes.
