O n the Skull of the Chinese Pug-nosed Spaniel or Lap-dog. By Dr. J. E . G R A Y , F.R.S., V.P.Z.S., & c Dr. W. Lockhart has kindly presented to the British Museum the skull with the atlas vertebra attached, and the penis bone, of a " Chinese pug-nosed Lap-dog, of a breed greatly admired among the Chinese." The skull is peculiar for the very large size, broad ventricose and subcubical form of the brain-case, for the great shortness of the face, and the shelving, almost horizontal, position of the nasal apertures ; the bones of the face are regular, symmetrical; the forehead is rather concave ; the hinder part of the face and the back of the lower jaw are very broad behind ; the nasal bones are well developed, and extend up behind between the orbits nearly to the forehead ; the teeth are well developed and in good condition; the hinder parts of the tooth-line are very far apart, from the great breadth of the short palate ; the two hinder upper grinders, which are under the front edges of the zygomatic arch, are placed angularly with regard to each other. i <. i i ,i in. lin.
