The lobes are separate in Pi/tlwn, of a subcircular flattened form, suspended cluster-wise by ducts of from six to twelve lines in length, before uniting into the com- mon canal. The pancreas has a close texture in herbivorous Clie- lonia, forming a tliin layer, spread out in the duodenal mesentery, fig. 305, where it branches into numerous lobes.
