This may be instanced in the second family, whose remains we 
shall have occasion to inquire into ; since, in speaking of the amphibia, 
the walrus, the seal, dugong, and lamantin, which constitute this 
family, are all referred to ; whilst, in the Linnaean system, the 
trichecus, lamantin, and dugong, are found with the elephant, sloth, 
and other land animals, under the order Bruta ; and the seals, with 
the dog, cat, &c. under the genus Ferai*. 
The remains of the family of Gets or Ceti, composed of balcena, 
halenoptera, narwhalus, ananarchus, catodon, phylasus, physeterus, 
delphinus, delphinapterus, and hyperodon, having large spiracles in 
the top of the head, Jins without nails, and no hind feet, are, I believe , 
rarely found in a mineralized state. 
Two specimens, fragments of the long projecting and spirally 
twisted tooth of the narwhal, improperly named Monodon monoceros, 
or norwhalus, was in the IVluseum of Sir Ashton Lever, one of which 
I now possess, and strongly suspect it to have been found on the 
Essex coast. Plate XX. Fig. 1, is a tooth, probably of some animal 
of this order. It is imbedded in a grey limestone, and is said to have 
been found in the neighbourhood of Bath. 
Amphibia, comprising pocha, trichecus, dugong, and lamantin, 
and having four paws in the form of Jins, and frequently with un- 
guiculated toes, have left very few fossil remains. 
M. Renou, professor of Natural History at Angers, found several 
bones of the lamantin (Manutus), in that part of the department of 
Maine and Loire which is situated to the south of the Loire, and on 
* Mr. Pennant observes : “ To have preserved the chain of beings entire, Linnaeus should 
have made the genus of Phocce, or Seals, and that of the Trichecus, or Manati immediately 
precede the whale, those being the links that connect the mammalia with fish ; for the seal is, 
in respect to its legs, the most imperfect of the former class ; and in the manati the hind feet 
coalesce, assuming the form of a broad horizontal tail. British Zoology, Vol. III. p. 44. Cuvier 
considers the lamantin, the dugong, and a supposed lamantin, seen by Steller, in Beering, and 
possessing a hide like the hoof of a horse or an ox, as forming three distinct genera, composing 
a very different family from the seals, and which come as near to the ceti, as the pachydermata 
do to the carnivorous animals.
