[CHAP. The most remarkable feature in the face is the form andposition of the anterior narial orifice (an). It is wide trans-versely, very short from above downwards, placed very high,and is directed upwards and forwards, almost as much as inthe Whalebone Whales. The nasal bones (JVa) which boundit above are very thick, short, broad behind, and conicalin front, and contain large air-cavities. The inferior andlateral margins of the orifice are formed entirely by the pre-maxillae (PMx\ which send processes up to join the nasalsand frontals. In front of the nares the face is prolongedinto a somewhat quadrate, depressed, alveolar process, trun-cated in front, concave above, rounded laterally, formed bythe premaxillas above and at the sides, and by the maxilla
