It is interesting, therefore, to note that the early indifferent 

 sexual gland liad become an ovary, but had retained a large part 

 of what would become the vas deferens in a male specimen. 



The fahe calls for little remark, as it resembles in many 

 points that of the human tuba Fallopii. It has a mucous 

 membrane consisting of columnar epithelium on a basis of con- 

 nective tissue and thrown into folds, especially in its outer part. 

 Circular and longitudinal unstriped muscular fibres form the 

 wall, which is covered externally with peritoneum. The cornu 

 has a very well-formed and thick mucous membrane with many 

 glands (fig. 30). The interglandular connective tissue consists of 

 a homogeneous basis ami connective tissue corpuscles. The epi- 

 thelium lining the glands is well formed and columnar, with 

 large nuclei and nucleoli. In tlie lower part or cervix the 

 epithelium is columnar and narrow like the cervical epithelium 

 of the human uterus. The muscular wall is thinner than that 

 of the mucous membrane, and has longitudinal (outer) and 

 circular muscular fibres, with some interlacing ones. The inter- 

 glandular connective tissue passes into the wall, and thus 

 vessels enter the mucous membrane from it. Near the tube 

 and ovary the epoophoron is seen well developed, and consists 

 on section of many tubules lined with epithelium of a columnar 

 but somewhat flattened type. 



The central vaginal portion is lined with narrow columnar 

 epithelium like that of the cervix, while that of tlic lateral 

 canals is squamous and many-layered. This is well seen on T.S, 

 (fig. 31), when one can further note that the muscular wall of 

 the lateral canals is much thicker than that of the central 

 Milllerian (three to four times). A romnion muacular coat 

 surrounds the lateral and central ^portions. The urethra is seen 

 cut in front in this T.8., and the blood-vessels lie at the posterior 

 angle of junction of the central and lateral portions. 



The bladder, ureter, rectum and anal glands present no novel 

 features. 



So far as the microscopical anatonry goes the cell structure 

 is not rudimentary, but like that of higher mammals.
