| The most conspicuous divergences from the normal are to be found in the cetacea and the Monotremata. |
| Albrecht went so far as to regard the cetacea as the nearest group of animals to the hypothetical Promammalia. |
| The size of the cetacea has been subjected to much exaggeration. |
| But here we give no such extracts, but content ourselves with four short skits, having the cetacea for their subject. |
| It is supposed to have lived in shallow seas and estuaries, and to have breathed air like the ichthyosaur, and our modern cetacea. |
| As in the cetacea, the nasal bones are limited in size, and the premaxillae send up processes to join the frontals and the nasals. |
