Rytina gigas, the Morskaia Korova. It is the Manate, or Vacca marina, Trichcchus Manalus of Muller • Rytina Stelleri of Illiger ; Stellcrus borealis of Desmarest ; the Manate of Pennant. It is a native of the Arctic Ocean—Behring's Straits. The Sea-Ape of Pennant, Trichechus Ifydropithccus of Shaw, Manatue Slink of Illiger, Dr. Gray suggests may belong to this family, if it is not a Seal.
loaail Cetacea.
The fossil remains of Cetacca have hitherto been found in the Tertiary Formations only. Bones from the Portland Stone which were at first thought to belong to whales proved to belong to the genus Cetiosaurus (Owen), the most gigantic of all the fossil rep tiles. (Owen, Report on British Fossil Reptiles' in Trans. Brit. Ass.' 1841.) Dr. Buckland, in his 'Bridgewater Treatise,' remarks that the seas of the Miocene and Pliocene periods were inhabited by marine Mammalia, consisting of Whales, Dolphins, Seals, Walrus, and the Latnantin or Manatee, whose existing species are chiefly found near the coasts and mouths of rivers in the torrid zone.
Manatidce. Cuvier figures and describes the remains of a Manatee differing from the existing species. Specimens were collected from various parts of France, and he states it to be very certain that an animal of the genus Manatus, a genus now peculiar to the torrid zone, inhabited the ancient sea which has covered Europe with its shells, at an epoch posterior to the formation of the chalk, but anterior to that when the gypsum was deposited and the Palcrotherium with its con temporary genera lived on the soil of France. (` Oss. Foss.') Delphinidcr. Cuvier notices and figures, with an accurate descrip tion, the remains of a fossil Dolphin, approaching the Grampus and Delphinus globiceps, from Lombardy, the skeleton of which was found nearly entire by M. Cortesi ; and another with a very long symphyais of the lower jaw from the department of Landes. Also a fossil Dolphin closely approximating tho common Dolphin from the same locality, and another from the Calcaire Greasier of the department of Orne. (`Oss. Foss.) M. von Meyer refers to these and another (Grateloup, Ann. Gdner. d. Sc. Phys.' iii, a. 68, t. 36 ; Taylor, 'Magazine of Nat. Hist.' March, 1830, s. 262), giving the following names :—Delphinus Cortesii, D. macrogenius, D. longirostris. Palteologica.) Monodon. Cuvier collects notices of fossil fragments of the Narwhal from Parkinson and Georgi. lie adds that lie himself saw a broken Iu the American Journal of Science' for April, 1843, is Notice of the Discovery of a nearly complete Skeleton of the Zygodon (Zeuglodon) of Owen (Basefosaurus of Harlan) in Alabama,' by S. B. Buckley, A.M.
The entire length of the skeleton, including the head, is described as nearly 70 feet, and was imbedded "in a marly limestone soil" on the plantation of Judge Creagh, the same gentleman who had forwarded the bones to Dr. Harlan. This discovery entirely corrobo rates the conclusions to which Professor Owen came iu the memoir above quoted. Bones of this gigantic fossil Cetacean have been also
found near the Washita River in Louisiana, and have been seen in Washington County, Mississippi : from thence, Mr. Buckley adds, they have been found in several places as far east as Claiborne, on the Alabama River. The skeleton is now at New York.
Balwnidcr.—J3ala'noplera. Cuvier figures and describes the skeleton of a fossil whale, which he considers to have been a sub-genus of ------ Jiahreoptera, or 'torque', found in Lombardy by M. Cortesi, on the oast flank of Monte Pu'gnaw° (Apennines) in 1S06. envier calculates the entire length at 21 feet, French; observing, that if the animal was adult it was a very small 'torque]. Another skeleton of the same species', not more than 12 feet 5 inches long, was also discovered by 31. Cortesi in similar beds, and a neighbouring valley near a small stream which falls into the Chiavenna, one of the tributaries of the Po. (' 0s Foss?) Bolcom. Numerous remains of Balatue have been found in the Tertiary Formations. Cuvier mentions a considerable fragment of the skull of a Bala-na disinterred in the Rue Dauphine at Paris in 1779. Daubenton came to the conclusion that the whale to which it belonged must have been 100 feet long; but Cuvier, on satisfactory calculations, reduces the length to CO feet, and states his opinion that it is an unknown species. ('Oss. Foss?) Dr. Mantel' detected the remains of Balerna in Sussex (Brighton Cliffs). In the Red Crag of Felixatow the tympani° bones of whales are frequent, whilst their bones are so numerous as to constitute a considerable portion of the phosphatic substances which are now dug from this formation under the name of Coprolite. From the form of tho tympanic bones, which he calla Cetotolites, Professor Owen has named four species of Bahrea : B. affinis, B. &Yalta, B. gilibosa, and 'B. emarginata. (Owen, Brit. Foss. Siam.') Phocama. Professor Owen refers tho fossil found in the Lincoln shire fens to this genua, which Dr. Gray places under the genus Orce.
J'hyseterides Teeth of the ,Physeter macrocephalus have been found in the Tertiary Beds of Essex and in other parts of Great Britain. From the section of a tooth found in the Red Crag at Felisstow, Suffolk, Professor Owen proposes to call the animal to which it belonged Balamodon physaloides.
