Greater and smaller parts of thirteen bands of the cara-pace are preserved. The skull is short and wide. The superior surface is nearly flat fromthe posterior border to between the nostrils. The muzzle does not projectbeyond the mouth border. The orbits and nostrils are not superior in direc-tion,. although the superior orbital border is excavated. The nostrils are.
