not meeting the oesophagus for some distance below the 
transverse septum. 
The lower lip of the large anterior funnel wraps over the 
top of the lateral mesentery as shown in Fig. 10, oi.f. It also 
extends round the sides and inner ends of this mesentery 
where it is free from the oesophagus (Fig. 14, «./.). The top 
of the funnel is closely applied to the septum (Fig. 8, n.f.). 
Below the funnels the duct runs downwards for a short dis- 
tance close to the mesentery in the anterior ccelom, then

turns outwards, and for the rest of its length is embedded in 
the basement tissue of the body-wall of the trunk. About 
•5 mm. below the septum it bends on itself. The ascending 
pait of the tube is often much distended; it passes obliquely 
upwards externally to the nerve-cord on the left side 
(Fig. 14, n. d.), and on reaching the collar region narrows 
considerably and runs forwards embedded in the walls of the 
anal papilla to open a, little in front of and below the anus 
(Fig. 11, ?i. p.). 
The funnel consists of deeply staining ciliated epithelium 
and the duct is lined with ciliated cubical cells as usual.
