Later, as the animal slowly glided along, it presented the appearance seen in fig. 3. The body was depressed pyritbrm, with the posterior nar- row end crowded with long ])apilla\ In this condition it measured mm. long. Eight hours subseciuently, the same individual measured mm. long by nnn. broad. In another instance I observed an active, well-fed Dinamocba in the act of swallowing a filament of Bambusina.
