tions are rather siiddenly altered. The walls become consi- 

 derably thickened and the lumen of the canal is soon narrow- 

 ed by an irregularly transverse fold which in two places 

 increases in size so as to form two large rugosities or warts, 

 each densely beset witli small papillte. The two large rugo- 

 sities do not lie opposite each other, but alternate in such a 

 manner that the one on the dorsal wall is situated a little 

 more distally and the one on the ventral wall a little raore 

 proximally. By this arrangement the passage becomes doubly 

 blocked up. This formation corresponds no doubt to the os 

 uteri of other animals which in this case has been more 

 strongly developed at two places and correspondingly less 

 between those. Any corpus uteri cannot be spöken of in this 

 animal. The lower part of the cornua are certainly exter- 

 nally confluent to an extent of about 12 mm. but internally 

 the division is complete to the portion described above and 

 regarded as corresponding to os uteri. The cornua uteri are 

 thinwalled and have a length of about 4^ 2 cm. They are 

 flat and have in this state a breadth vårsång from 6 to 9 

 mm. They are not evenly tapering into the tuhce FaUopii, 

 but are almost broadest at their abruptly rounded upper or 

 inner end. There is thus no difficulty to determine the limit 

 between a cornu and the corresponding tuba which latter has 

 a breadth of only 3 mm., or hardly that much, at its lower 

 extremity. The length of the tiiha is about 2^ 2 cm. The 

 ovary is a flattened body longer than broad. It is enveloped 

 in a peritoneal pouch with a longitudinal opening which ex- 

 tends along the greater part of the organ. This opening is, 

 however, covered by the infundihulum tuhce and adjoining 

 mesenteric folds so that the ovary is completely enclosed and 

 not visible before the covering parts mentioned are laid to 

 the side. 



In the description above, the clitoris was only described 

 with regard to its shape and external features, its internal 

 structure is, however, well worth considering. Alread}'^ at 

 an external inspection it appears to be stiff and cannot be 

 bent. This fact is due to the presence of a very well de- 

 veloped ossicle which extends from the extreme tip to the 

 base of the clitoris and measures about 16 mm. in length 

 The shape of this ossicle niay be seen from fig. 5 (oc). Its
