Thick, containing rolled fossil bones, cetacean and fish teeth, and shells of the Crag period, with nodules or pebbles of phosphatic matter derived from the London Clay, and often investing fossils from that formation.
NARWHAL, the Scandinavian name of a cetacean (Monodon inonoceros), characterized by the presence in the male of a long horn-like tusk.
It is the commonest cetacean in the seas round the British Isles, and not infrequently ascends the Thames, having been seen as high as Richmond; it has also been observed in the Seine at Neuilly, near Paris.
BELUGA (Delphinapterus leucas), also called the "white whale," a cetacean of the family Delphinidae, characterized by its rounded head and uniformly light colour.
DOLPHIN, a name properly belonging to the common cetacean mammal known as Delphinus delphis, but also applied to a number of more or less nearly allied species.
Smaller members of the cetacean order, none exceeding io ft.
Andrews has, moreover, not only brought forward additional evidence in favour of this most remarkable line of descent, but is confident - which Professor Fraas was not - that Zeuglodon itself is an ancestral cetacean, and consequently that whales are the highly modified descendants of creodonts.
He believes that the cetacean approaches not only rocks, but ships, in the hope of freeing itself from its lodgers.
