the clitoris, which in a few days assumes a purple hue, 

 and by the middle of March a perforation appears in this 

 livid wrinkle on each side of the median line. Towards 

 the end of March these two perforations coalesce, and the 

 vagina is then open for penetration in the usual way. I 

 have not found any internal hymen whatever. It is 

 exactly at this time that males are caught with unmis- 

 takable signs of recent copulation. I have observed that, 

 before the vagina is open, and before even the wrinkle 

 appears, the vagina and uterus are enormously developed 

 (Fto-s. 21 — 24).* 



The proportion of males to females seems equal.

* The Rev. F. Jourdain has brought to my notice a remarkable 

 parallel between the female generative organs of the mole and those of 

 Hyicna Croatia as described by Morison Watson {Proc. Zool. Soc, 1877, 

 p. 369; 1878, p. 416 ; and 1881, p. 516). Briefly, in H. crocuta the sexes 

 are barely distinguishable ; the female possesses a clitoris 6^ inches from 

 root to tip, which is perforated by the urino-genital canal ; the vulvae are 

 absent. After parturition the lower side of the clitoris opens out. The 

 likeness is further heightened by the scrotum of the male being imitated ih 

 the female, and there is no appearance of a vagina.
