Fig. 1. Diagrammatic representation of the positions and relative proportions of the 
organs of Bijpalium Diana in the anterior portion of the body, as seen from 
beneath, enlarged two diameters. The digestive tube (D) is represented only 
in front of the pharynx, and its diverticula only at the most anterior portion 
of the body. In the peculiar cheese-knife-shaped extremity the digestive tube 
is seen to ramify in an arborescent manner. The ovaries (OV.) lie just behind 
the angle formed by the union of the broad head with the body, and their 
long ducts (OD.), attached to them on their exterior aspect, pass down the 
body, coming into close contact with the sheath of the pharynx, and crossing 
the vasa deferentia (V. D.), and making a sharp turn inwards, pass into the 
uterus (UT.). Between the angle formed by this sharp turn and the pharynx 
some short branches, which slope backwards and outwards, join the oviducts. 
The testes (T, T) commence a short distance behind the ovaries, and are 
slightly external to them in position. There are about twenty-four pairs of 
them. They communicate with a pair of ducts (V. D.), which, skirting the 
sheath of the pharynx and here coming into close relation with the oviduct, 
pass to the inner side of the latter, and turning sharply backwards upon these 
lines, enter the sheath of the penis (S. P.).
