chamber wherein the chyle becomes converted into chyme, and from 
this chamber the digested food passes by means of a contractile 
pylorus ( q ) into the intestine (g), which is highly ciliated, and 
wherein the faeces become formed, by the rotation of the contained 
cilia, into well-defined pellets, that are ejected by a muscular con- 
traction of the long rectum (h) to the anus (i), which acts as the 
common duct for both the faeces and the ova ; and the monocyst at 
its junction with the anus is seen to be considerably folded in upon 
itself. In the particular instance of M. pilula the faecal pilules 
attain a much greater bulk than in any other species, and with 
such pilules this little Melicertian fortifies the gelatinous basis of 
the theca, which, like every Form, is secreted from the figurum (r), 
that in this particular species is unciliated.
