no 



and fully developed normal adult oviducts. Vasa efferentia and 

 seminal vesicles. Four openings into cloaca. Sections showed 

 almost ripe sperms, and immature ova scattered irregularly 

 throughout the whole of both testes. Pigment cells at the sur- 

 face of anterior end of testes in association with ova. 



4) Maeshall. C) Male with right testis almost completely absent, 

 and having no vasa efferentia, which however were present on 

 the left side. Miillerian ducts convoluted and exhibited uterine 

 dilatations. Seminal vesicles. Sections showed normal testis 

 with no ova. 



5) Marshall. D) Female with ovo-testis and vasa efferentia on 

 right side. Ducts those of normal female with four openings 

 into cloaca. No seminal vesicles. Ovary on left side had vasa 

 efferentia. Sections showed that testis portion of ovo-testis 

 greatly predominated. Smaller ovarian portions contained large 

 number of surface pigment cells, and a few true, and a larger 

 number of degenerate, ova. Ovary on left side was abnormal 

 in the majority of the ova being in a degenerate condition, 

 and the outer coat of the ovary densely pigmented. 



6) Marshall. E) Male with greatly aborted testes — consisting of 

 fat only. Normal convoluted Miillerian ducts. Seminal vesicles. 



7) Kent. Male with well developed convoluted oviduct (but no uterine 

 segment) and ovo-testis (?) on right side. Ovarian portion showed 

 outlines of ova (?) at anterior end of testis, which was much smaller 

 than its fellow on the other side. On the left side the Miillerian 

 duct was straight and rudimentary. Four openings of ducts into 

 cloaca. Seminal vesicles. Male glandular enlargement on fore- 

 foot. No sections were cut. 



8) RiDEWoOD. This specimen (a male) almost exactly resembled 

 that now described, with two main points of difference: a) the 

 right oviduct was convoluted; b) seminal vesicles were present. 

 It does not appear whether sections were cut or not, so that 

 the true nature of the "ovo-testis" cannot be described. 



9) Smith. Female with two "ovo-testes". On the right side the 

 testis portion predominated, but there was a somewhat large 

 and convoluted oviduct. The outlines of "ova" could be traced. 

 On the left side the ovarian element was the more conspicuous — 

 showing "eggs" in various stages of development. Oviduct large 

 and quite normal. Uterine segments on both sides. No seminal 

 vesicles. Four openings of ducts into cloaca. Male enlargement 

 on fore-foot present on right side only. No sections were cut.
