In the first place, the number of molars is reduced to one pair in the upper and two in the lower iaw, while the lower carnassial has no cusp on the inner side of the blade, and its posteriiir heel is secant Instead of tubercular, so that practically the entire tooth is reduced to a cutting blade. The last member of the dog family is Lalande's fennec (Otocyon mcijnlotis) of South Africa, which, while agreeing in many respects with the true fennecs, has very much larger ears, but is specially distinguished by having four pairs of lower molar teeth, and either three or four pairs of the same in the upper jaw, the total number of teeth thus being either 46 or 48. Its habits are like those of the fennecs. In the_ three remaining families of the terrestrial Carnivora the auditory bulla of the skull possesses a simple undivided septum, and its bony external tube, or meatus, leading to the outer ear, has its lower margin considerably produced, while the triangular paroc- cipital process stands quite apart from the bulla. In the in- testine the blind appendage or coecum is entirely absent. The bears themselves are specially characterised by the broad, flat, tuberculated crowns of the molar teeth, of which there are two upper and three lower pairs ; and likewise by the rudi- mentary development of the first three pairs of premolars in each jaw, which are in many cases entirely lost.
