in South Africa that lives wholly upon
birds eggs. It has no teeth or signs of
teeth in the mouth, the dental array being
located in the stomach. Buckland says

pent had its teeth in the proper place.
When the egg is safe inside the abdom-
inal walls contract and crush it against
the long row of vertebral teeth.
