'A Case of Hermaphroditism in Bana temporaria. 



By Frank J. Cole, Zoological Laboratory, University of Edinburgh. 



With 4 Figures. 



The specimen to be described was a young and apparently im- 

 mature male, which was being dissected by a member of the junior 

 summer class, and which was kindly placed at my disposal for de- 

 scription by Dr. Beard. Although the anomalous condition of its 

 reproductive organs was not noticed immediately, the tissues were in 

 a fair state of preservation, and quite fit for sectioning. On being 

 carefully dissected, the following anatomical features were made out: 



Left side. The Müllerian duct opened into the body cavity 

 at the root of the lungs as in the normal female. It was pigmented 

 and fairly convoluted, and after swelling into a non-glandular, non- 

 pigmented "uterus", opened normally into the cloaca. The ureter 

 was formed by the junction of three small tubules, and did not expand 

 into a vesicula seminalis. Posteriorly it was very closely attached to 

 the Müllerian duct — thus retaining its primitive position, but opened 

 separately into the cloaca, and did not, as at first appeared, become 

 confluent with Müller's duct. The ovo-testis resembled that descri- 

 bed by Kent (6), Ridewood (7), and Smith (8), having a smaller 

 papilliform non-pigmented testis portion, and a larger densely pig- 

 mented ovarian portion (see Fig. 1 and la). The testis portion was 

 not so conspicuous dorsally. Careful examination showed that there 

 were only two vasa efiferentia, but the divisions of the renal artery 

 to the ovo-testis might well have been mistaken for efferent canals.
