The teeth are represented as they appear in transverse sections of the jaws, the heavy lines indicating the keeled enamelled crowns of the teeth. Thus although. in both _ the upper and lower jaws the teeth replace each other from the inner side, yet the enanielled surface ofthe CIOWH Of the teeth are on the inner side in the lower jaw but on the outer side in the maxilla.
