Show 44 DR. j. E. G R A Y O N T H E SUIDAE. [Jan. 9, parallel with the tooth-line ; orbit small, incomplete behind, concave half ring beneath, on the cheeks and upper part of the front of the zygomatic arch ; occipital end much dilated on the sides, forming a case for the hinder part of the temporal muscle. Teeth moderate. Tail rudimentary ; caudal vertebree six (Gerrard). De Blainville's figure of the skull on the skeleton (Onguligrades, Sus, t. 3) is not characteristic; the concavity in front of the lower part of the orbit is not sufficiently marked. The skull figured as that of Sus torquatus on tab. 5 is that of Dicotyles labiatus. Dr. Spencer Baird's figure of the skull (t. 87) is much shorter and more ventricose than any of our specimens; the form of the ridge on the cheek is very imperfectly represented.

Notophorus torquatus had a young one in 18G0, the first occasion that the animal has bred in confinement in England (Sclater, P. Z. S. 1860, p. 443). The skulls of the three old [males ?], having larcje canine teeth, are rather larger than the other, and they have a well-marked oblong slightly sunk concavity in front of the orbits. One adult skull, in the "Museum, with large short thick canines, has this part of the skull, which is concave in the three other skulls above referred to, flat. The angle of the lower jaw in the old skull becomes much di- |
