 The face is broad, with a short snout and rounded cranium, which encloses a large brain with well-developed cerebral hemispheres.The nose-leaf is well developed, with a long and broad spear-like projection from the upper surface, while the ears are also broad, and long enough to reach the tip of the snout when projected forward.Males have a large, glandular sac in the throat region, which is almost entirely absent in females.
