再びヌマガエルに見出された卵巣睾丸について Further Observation on the Ovotestes found in Rana limnocharis
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.
