696 ANATOMY OF VERTEBRATES. 



continued in a tortuous and somewhat spiral course to the prepu- 

 tium clitoridis, to one side of which it is adherent : the extremity 

 of the preputium forms a conical prominence external to the ante- 

 rior margin of the urogenital canal. The ' plexus retiformis ' 

 forms two large bodies. 



In the Pigmy Musks or Chevrotains ( Tragulus) the ovaria are 

 smooth oblong bodies with a somewhat angular contour. The 

 oviducts pursue a scalloped course along the edge of the broad 

 ligament, and terminate in an expanded elongated pavilion at the 

 outer part of the circumference of the capsula ovarii. I found the 

 cornua of the uterus are unequal in size ; the right was the largest 

 in the specimen examined ; its inner surface was smooth, the utri- 

 cular pores generally diffused, without any appearance of cotyle- 

 donal processes, implying an uniform and stunted villosity of the 

 foetal chorion, as in the Camel tribe. 1 The inner surface of the 

 vagina has many parallel longitudinal folds, the abrupt termina- 

 tion of which indicates the beginning of the uterus, there being 

 no os tineas. The vulva is close to the vent. 



In horned Ruminants the lining of the cornua uteri shows 

 smooth prominences, devoid of utricular pores, called ' caruncles ' 

 or cotyledonal processes, fig. 546, e, e, increasing in number with 

 the size of the species. In Cervus rufus and C. capreolus there 

 may be from four to six in each cornu, longitudinally disposed: 

 in the Giraffe there may be eighty. In the Cameline group we 

 have seen that the greater part of the capsula ovarii is formed by 

 the expanded fimbriated aperture of the oviduct itself, which is 

 of very large size. In Deer, Antelopes, Bovines, and Ovines the 

 ovarium, ib. k, is lodged in a depression or sacculus of the broad 

 ligament, which is more or less deep, and has its apertures more or 

 less contracted in different species. In the Giraffe this sacculus is 

 wide and deep, and incloses almost the whole of the ovary. The 

 fimbriated extremity of each oviduct is expanded upon the outer 

 margin of the ovarian capsule, as in fig. 546, i, i ; the inner surface 

 of the pavilion is beset with numerous fine oblique strias, and is 

 further increased by narrow folds of lamina? converging toward the 

 contracted opening of the duct. The oviduct forms three or four 

 wavy folds, and is then continued along the walls of the wide 

 ovarian capsule to the extremity of the uterine horn, which makes 

 an abrupt curve to meet it. Each cornu becomes bent in a 

 spiral form when distended with fluid: four longitudinal rows 

 of compressed caruncles project from the inner surface. The 

 cervix of the uterus is occupied by two circular series of close-set,
