The Seal, which is one of the marine carnivorous mammalia, also occurs in a fossil state in England. A femur of a species of Phoca has been found, with the remains of a Monkey and Bat, in a tertiary deposit in Suffolk. In the tertiary strata of Malta an extinct species of Seal has also been discovered. In the bone-beds of New Zealand my son frequently found bones and teeth of Seals, probably of the species now inhabiting the South Pacific. (Petrif. p. 130.)
Of the Insectivora, the fossil remains of several genera occur. In England, the jaw with teeth of a large species of Mole (named Palæospalax,[773] ancient mole), has been discovered in a lacustrine deposit at Ostend, near Bacton, on the coast of Norfolk, associated with bones of Elephant, Deer, Roebuck, and Beaver. This animal must have been as large as a hedgehog. The only part of the skeleton hitherto obtained is a portion of the left side of the lower jaw, containing six molars; its natural affinities have therefore been inferred from the characters of the crowns of the teeth.

FOSSIL CHEIROPTERA AND QUADRUMANA.
The Cheiroptera (hand-wings) or Bats, are mammalia which have the power of flight, from the bones of the phalanges or fingers being enormously elongated and giving support to a fine membranous expansion; they are rarely found fossil, although, from their habits of haunting and hybernating in fissures and caves, their skeletons often occur mingled in the earth of the floor of caverns, and imbedded in crannies of rocks, with bones of extinct animals.
The remains of a considerable portion of the skeleton of one species of Bat was discovered by Cuvier in the gypsum of Montmartre,[774] and another example in a gypseous deposit, at Köstritz, in Germany, with remains of extinct species of other mammalia. Two instances of British fossil Bats are recorded;[775] the one from Kent’s Cavern, collocated with the extinct Carnivora, and referred to the Horse-shoe Bat (Rhinolophus); the other from Kyson, in Suffolk, found in the same deposit with the remains of the Monkey, presently to be noticed.

VIII. Fossil Quadrumana, or Monkeys.—The illustrious Cuvier, when commenting on the extraordinary fact, that among the innumerable fossil relics of the mammalia which peopled the continents and islands of our planet, through the vast periods comprehended in the tertiary formations, no traces of Man or of his works occur, emphatically remarked, that it was a phenomenon not less surprising, that no remains of the quadrumanous races, which rank next to Man in physical conformation, should have been found in a fossil state; and that the circumstance was the more remarkable, because the majority of the mammalia found in the younger and older tertiary strata have their congeners at the present time in the warmest regions of the globe; in those intertropical climates where the existing quadrumana are almost exclusively located.[776]
