Very young specimens are exceedingly rough. SeeFig.—The plastron is small and narrow, exposing a great amountof the fleshy parts. The under-surface of the tail is covered with large shields. As with all of the very aquatic chelonians the feet are broadand extensively webbed. Both front and rear pairs are pro-vided with large and coarse nails. Most characteristic about this, and the allied species, isthe huge, powerful head; the upper and lower mandibles ter-minate in strong hooks. Though the eyes are comparativelysmall, they are very keen of vision. The head cannot be com-pletely withdrawn into the shell, nor can the tail—nearly aslong as the upper shell—be protected beyond folding againstthe lower margin of the shell. Colouration.—Carapace, dull olive or dark brown, withlittle or no markings; plastron dull yellow. The upper portionof the head is very dark as is the upper-surface of the limbsand tail; beneath, these members are yellowish. 12 THE REPTILE BOOK PLATE VI.
