38 DESCRIPTIONS OF PREPARATIONS. 



the homologue of the * ligamentum rotundum ' of anthropotomy and of the gubernaculum testis 

 in the male, passes downwards and inwards, whilst from it and the Fallopian tube beyond it, 

 that part of the ' broad ligament ' known as < ala vespertilionis ' passes to the funnel-shaped 

 opening of that tube. 



f, Fimbrjated and funnel-shaped opening of the Fallopian tube ; the so-called ' Pavilion ' or ' Infun- 



dibulnm,' the mucous orifice looking into the peritoneal cavity inwards and backwards from the 

 posterior aspect of the broad ligament. 



g. Ovary, connected on the right side with the pavilion by the tubo-ovarian or ' infundibulo-ovarian' 



ligament, formed by the drawing out of the periphery of the pavilion, and on the left with the 

 uterus of that side by the ovarian ligament. There are no fimbriae on the infundibulum of the 

 Monotremata, and its outer periphery is almost entire in the placental genus Sus, but they are 

 present, so far as is known, in all other Mammals. 



h. Rectum, with one hydatid affixed to it. 



i. Ano-preputial glands. Between the smaller of these glands and the rectum is seen part of the 

 gland homologous with Cowper's gland and known as the gland of Bartholini. 



J. One crus of the clitoris, with muscle in relation with it. 



k. Rectum ad- external outlet of urogenital canal. 



with ova nearly mature ; they are seen to be attached to the infundibular 

 fimbrjate opening of the Fallopian tubes on either side by one of the 

 fimbriae of that opening, the so-called tubo-ovarian ligament, which 

 secures that an ovum on escaping from its Graafian follicle shall readily 

 find its way into the oviduct. The ligaments and peritoneal laminae 

 passing from the opening of the oviduct and from the ovary to the proxi- 

 mal end of the uterus cause the oviduct to take a very contorted course. 

 In some mammals, e.g. Talpa^ Canis, Ursus, Meles, the peritoneal laminae, 

 which here form only a widely open capsule for the ovary and infundibulum, 

 coalesce and form an all but completely closed pouch in which ovary and 

 opening of oviduct are both enclosed, so that an escape of an ovum into the 

 peritoneal cavity becomes nearly impossible except through the small 

 orifice near the uterine cornu where the interior of the pouch communicates 

 with the peritoneal cavity. In the two carnivora last specified, even the small 

 orifice thus left is frequently filled up by a hernia-like protrusion into it of 

 one of the fimbriae of the infundibulum ; and the ovary, a small portion of 

 which is usually to be seen at that orifice, is thus cut off from view and from 

 access to the peritoneal cavity. In some other Carnivora (Lutra and 

 Mustela), at least in the young state, this orifice appears to be entirely 

 closed by an overgrowth of peritoneal membrane.
