cious. It consists of two separate portions, the hermaphrodite and 
the male ones, combined only by means of the external ciliated 
furrow. In the median part of the body we find the hermaphrodite 
giand situated to the right of the liver 
and extending beneath it backwards and 
above the gizzard in front. Its ovarial 
acini are arranged peripherically. On 
its posterior and upper side, just be¬ 
neath the point where the intestine 
traverses it, the spermoviduct takes its 
origin. It follows the left side of the 
intestine backwards. In front of the 
rectum it widens to an ampulla, which 
after some convolution opens in the 
large, much folded albuminiparous giand. 
With the same giand, which has a thick 
cyanophil epithelium, is connected a 
Shell giand with an erythrophil granular 
epithelium of high cells. From the right 
side of the giand complex the uterus of the anatomy ot

to the right in the posterior end of the 
body. Before its mouth it receives a narrow duet which differs 
from the spermoviduct in lacking in its interior the ciliated epi¬ 
thelium; it ends blindly and is certainly to be interpreted as a 
bursa copulatrix. 
From the genital pore the seminal groove leads, as mentioned, 
to the male opening at the side of the mouth. The penis consists 
of two portions, a narrow and muscular atrial one, the penis proper, 
and a tubular giand forming a posterior prolongation of the former, 
somewhat wider than that and composed of large glandular cells. 
The penis is a muscular cord with a fine central canal allowing 
the sec'retion of the tube to pass. The whole apparatus lies freely 
beneath and to the right of the pharyngeal bulb. 
The kidney is a large sac on the right side and has its walls 
entirely smooth. It extends from the hermaphrodite giand in front, 
close beneath the tissues of the notum, to the surroundings of the 
anus, where it forms some small descending lobes. The nephroproct
