Female organs of Osphranter erubescens (¢ natural size). As explained in the 
text, nearly the whole of the urogenital passage has been cut away, but the 
drawing shows the median canal, m.c, completely laid open along the ven- 
tral median line and the cut edges pulled apart by the threads a,, a,. 
Emerging from the right os uteri, 7.0, is the umbilical cord, w.c, which 
' is seen to pass along the median canal, m.c, and to emerge from this by an 
opening, X. To the attenuated extremity of this cord is attached the 
embryo, HE. Other references :—?r.uf, /.uwt, right and left uterus, the former 
considerably enlarged and partially laid open ; /.ov, left ovary ; 6/, bladder ; 
r.lc, llc, right and left lateral canals; 4, c, bristles passed through their 
cut ends; d, bristle passing into urethra similarly cut across just before 
its termination in the urogenital passage ; 7.0, /.0, right and lett os uteri ; 
rur, lur, right and left ureters. 
The openings from the lateral canals into the median are concealed 
from view, but were to be found just above the internal extremities of the 
lines 7.0, 7.0. Bulgings appear at the commencement of each lateral canal, 
crossed in the sketch by the same lines, 7.0 and /.0, but there was nothing 
inside to account for the swellings.
