Fia. 44. The Colombian Charapero, or turtle-dealer, on the upper Peruvian Amazon. His raft 
is of Balsa-wood; his turtle-pen forms the ground-floor, his dwelling the upper story.

specimens of intermediate size of var. inornata Pellegrin than to any other. 
Comparing adult specimens with those of O. agassizii of equal range in size, 
I find them: 
More elongate, narrower, with more rounded contours transversely; the width
