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 Fertf*. 



The remains of the family of Cete, or Ceti, composed of bal<e?ia, balenop- 

 tera, narwhalus, ananarchus, catodon, phylasus, physeterus, delphinus, delphinap- 

 terus, and hyperodon, having large spiracles in the top of the head, fins 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 narwhalus, 

 was in the Museum of Sir Ashtori 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 im- 

 bedded in a grey limestone, and is said to have been found in the neigh- 

 bourhood of Bath. 



Amphibia, com prising phoca, trichecus , dugong, and lamantin, and having 

 four paws in the form of fins, and frequently with unguiculated toes, have left 

 very few fossil remains. 



M. Renou, professor of Natural History at Angers, found several bones 

 of the lamantin (Manatus), in that part of the department of Maine and 

 Loire which is situated to the south of the Loire, and on the two sides of 



* Mr. Pennant observes : " To have preserved the chain of beings entire, Linnaeus should 

 have made the genus of Phoc/e, 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 manatithe hind 

 feet coalesce, assuming the form of a bro;id horizontal tail. British Zoology, Vol. III. p. 44. 

 Cuvier considers the lamantin, the dugong, and a supposed lamantin, seen by Steller, in Beer- 

 ing, 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.
