One of the illustrations showed that this young turtle—for it was a small specimen— possessed a peculiar and conspicuous hump in the median line on top of the carapace. Upon dissection, the cavity within this remarkable elevation con- tained no anatomical structures—in fact, it was practically empty.

This is well shown in the accompanying photograph, made by me shortly after the specimen was re- ceived. This turtle was kept in a small aquar- ium and fed with angling worms, which it greatly relished, but I soon discovered
