The present study was undertaken with the object of determining whetehr the hypopysis has some connection with sex reversal in amphibians. Hypophysectomized or thyroidectomized frog larvae (Rana japonica) were treated with estrone (1mg/1) from 105 days of age for 45 days and thereafter maintained without estrone up to 225 days of age. In both groups of animals ovaries were not affected by estrone, but the testes, in most cases, were feminized (Figs. 1, 2). The hypophysis therefore had no connection with gonad feminization. After the treatment was stopped, feminized gonads of thyroidectomized larvae were restored to the testes, all of the ovocytes were destroyed, and the luteal-like bodies were formed (Fig. 3). On the other hand, feminized gonads of hypophysectomized larvae seemed to have evolved into the ovaries (Fig. 4). It seems probable that when the hormonal treatment is stopped, the hypophysis controls the developmental fate of the gonad feminized by the action of estrone.

Ovotestes found in a female intersex specimen of Rana limnocharis were reported. 1. In both gonads the ovarian tissue is pathological: all ova are degenerating, theca and connective tissue are hypertrophic and fibrous, and the presence of polygonal masses of pigment is remarkable. 2. Islets of testicular tissue are scattered on the surface of both gonads. A testicular nodule lies at the anterior end of the right gonad. Vasa efferentia are not present. The spermatogenesis is normal. 3. Oviducts are well-developed. Seminal vesicles are not present. Secondary male sexual characters such as nuptial color, thumb pads, protruded larynx and vocal sacs are clearly recognized.
