 into it but into the prostate gland, as I have indicated in the drawing 

 (fig. 1). The anterior section of the vasa deferentia {o.d) as far as the 

 bursa copulatrix was very conspicuous, owing to the whitecolour of the 

 tubes (white from the contained spermatozoa) : the distal region of 

 the vasa deferentia was far less conspicuous, and I mistook them at 

 first for a mere ligament uniting the prostate with the surface of the 



Generative organs of Eudrihis.

 supposed ligament is really a continuation of the vasa deferentia. 

 Tliese tubes, although lying upon the bursa, are in no way adherent to 

 it, and can be readily lifted up with a dissecting-ueedle ; they are 

 then seen to be continuous with the prostate {pr,).
