Supplement to the catalogue of seals and whales in the British Museum

The atlas vertebra subcircular, rather broader than high. The central canal subcircular, in the middle of the body, widened above.

The rest of the animal not known; it is placed in Catodontidæ because this family is the only one that has the atlas separate from the cervical vertebræ and of the simple form.
