n its uppei side (fig. 16), a mass 1. 1' small clear, semiglobular, prominent papulae, 



which, when slightly magnified (fig. 171 were seen to Ik- composed of densel) crowded halls of a dia-

■-..I contained similar halls and tubes. Tlu- balls wire ovarial follicles with eggs in different 



i development, attached to a central testicular mass containing bundles of zoosperms. About 



medianly from the foremost part of the under side of the gland the hermaphrodite duct arose stretch- 



nterior genital mass. 



This anterior genital mass (fig. 18) was situated on the right side of the hulhus 



pharyngeus before the liver. Anteriorly and on the under side it was grayish, otherwise of a li.L, r ht 



-h white colour; the length was 5"" by a breadth of .yv : " and a height of 3"8 cni ; its lower sur- 



- slightly convex, the upper one strongly convex, posteriorly more abruptly shelving, anteriorly 



more gradually sloping; the fore end was a little pointed, the hinder end broader and rounded. Its 



I part was formed by the large mucous gland (fig. c8a); on the hinder end lay the spermatheca 



1 with its ratlu-r short duct; before and partly upon this (fig. [8) the large bag of the penis. 



The hermaphrodite duct (fig. 19a) stretches under the spermatheca and the bag of the penis and forms

when loosened : ther, had a length of about 15"" b) a diameter generally of 15 j' m "; fore-
