eating lateral branches on tiie outer side and a smaller number (about 

 lour or five) of less repeatedly dividing branches on the inner. 

 The foremost inner branches of both sides form a pair, and pro- 

 ceed at first 1)ackwards and towards the median line and tlien asfain 

 diverge, thus making the figure of two bows with their backs turn- 

 ed towards each other ; the Ijranches of tlie two sides l)eing, however, 

 often of unequal lengths. Common <jeuit(d opcmtuj close behind the 

 anterior sucker of the left side. Vcuifi club-shaped, of moderate length. 

 Ovanj 7uuch lobed, in the median line, at the beginning of the middle 

 third of the l)odN'. r'c/(?/^d arising from the ventral side of the an- 

 terior end of the ovary, proceeding forwards and towards the left dorsal- 

 ly to the yolk-duct, continued into the ootyp about midway between 

 the hinder end of the penis and the front end of the vitelline reservoir. 

 Uterus of moderate len<ïth, followino: the same «xeneral course as the 

 oviduct, opening into the genital atrium at a short distance from the 

 external opening of the latter. VitcUari urn nhnoat wholly confined to 

 the lateral and posterior regions of the body, but also following the 

 intestinal branches into tlie median region ; with a large yollc-dKCt just 

 inside the intestinal trunk on each side ; this yolk-duct, by its union 

 with a similar duct coming from the anterior part at the plane (jf the 

 front end of tlie (3vary, gives rise to the i)au-ed iiolk-duct, which unit- 

 ing with its fellow of the opposite side at the front end of the ovary 

 on the left side of the median line, forms here a liu'ge yolk-rcscrvoir. 

 From this tlie unpaired yolk-duct proceeds dorsad, anteriad, and towards 

 the right, and opens into the oviduct. Vuijinal opening a short dis- 

 tance behind the common genital opening, a little farther from the 

 median line ; the much convoluted vaginal can:d lies for the most part 

 just outside the vas deferens, is swollen into a comparatively small 

 rcceptaculum seininis near its external pore, and finally opens into the 

 yolk-reservoir. Testes smfdl, verv numerous, confined to the median
