cardia as the nerve-ring is in front of it, and pouring its excretion 

 through a long duct whose outlet is a large ampulla and ventral 

 pore just behind the nerve-ring. This latter encircles the oeso- 

 phagus squarely. The tail is conoid to the slightly swollen 

 terminus, its posterior two-thirds being covered with hairs. The 

 length of the two equal nearly straight pointed spicula is about 

 equal to the anal body-diameter ; their proximae are barely 

 cephaloid. The accessory pieces are nearly as long as the spicula, 

 are joined distally, and are capable of being extruded along with 

 the spicula. There is no supplementary organ or bursa. The 

 point where the testicles join is somewhat behind the middle of 

 the body. The food is vegetable.
