Opposite the fifth sub-ventral papillae, at some distance 

 in front of the anus, moreover one single papilla is found, 

 placed exactly in the ventral median line of the body, and 

 appearing as a very small circular ringlet in a ventral 

 view of the bursa : a similar median papilla has been 

 described by Butschli in Bhabd. pellio and Bhabd. 

 pellioides. 



The vulva, somewhat prominent, like the anus, is 

 constantly situated at a short distance behind the middle 

 of the body. The walls of the vagina are rather thick ; 

 nevertheless, they do not present the more or less intense 

 yellow colour which is often observed in other species, 

 because they are not chitinous. On each side of the 

 vagina two rather large, coarsely-granulated, roundish 

 glands are situated, one before and one behind it, which 

 empty into the vagina by rather long excretory ducts, 

 because the glands are lying on the lateral sides of the 

 body. The sexual organs are double and symmetrically 

 reflexed. In those adult individuals, in which the embryos 

 have already left the egg-shells and swim about in the 

 uterus, the anterior branch of the sexual apparatus extends 

 along four-fifths of the distance between the vulva and 

 the commencement of the intestine, the posterior branch, 

 however, along three-fourths of the distance between 

 vulva and anus. In those individuals, the uterus of which 

 contains only eggs, including more or less developed 

 embryos, the sexual organs extend somewhat less far. 

 The reflexed ovaries, which soon after the flexure become 

 narrow, are very long, and extend a little beyond the 

 vagina. 



Bhabditis oxycerca appears to be viviparous. A female 

 specimen that had lived some time in some humus, taken 

 from the Calanthe, and mixed with a little water, proved 

 to contain thirteen embryos, some of which had already
