Show 52 scarcely indicated. The lambdoidal suture shows two Wormian bones where it joins the sagittal, one being situated to the right, the other to the left of the latter, measuring 2cm .2 and 3cm .2, respectively. Another but smaller Wormian bone may be noticed, whefo the left lambdoidal joins the squamous suture. The mastoid processes are rather obtuse and small, the digastric fossa of the left being longer and deeper than that of the right, while the right mastoid foramen is larger and situated somewhat higher than the one opposite. The parietal eminences are not very distinct, although they may be recognized by viewing the skull from above; the temporal ridges are not indicated at all, and the right parietal foramen is situated before the left one and is about twice as large. Goronal suture rather straight, without many serrations. The frontal bone is without any median ridge or trace of suture, the eminences are but slightly developed, the superciliary ridges scarcely indicated, and the temporal ridges only well marked in the vicinity of the supra- orbital arches. The angle formed by the nasal bones with the frontal, and the curvature of the nasal bones are rather flat, nasal meatus rather round, anterior nasal spine moderately protradiug. The number of teeth in the upper jaw complete, the last molars on each side in the act of eruption. Teeth rather small, with the exception of the incisors, which are directed much more obliquely forward than downward; canines smaller than the incisors; only the crowns of second and third molars ground flat; the other teeth of the upper jaw scarcely showing any wear, while the incisors of the lower bear the marks of extensive use; not so, however, the molars, which are almost intact, at least those on the left side. Symphysis of the lower jaw scarcely visible, mental process tolerably developed, and incisive fossa of the right deeper than that of the left. External oblique line only well indicated near the anterior border of the ramus. Coronal process rather pointed; insertion, of the internal pterygoid muscle less than usually rough. Measurements.

Zygomatic diameter* Skull 2To. 3.- Plates 28 and 29, ( Fig. 13.) The skull designated by this number is rather thin, and was broken into a number of small fragments when brought from the field, and the pieces themselves were very fragile. It could, however, be sufficiently well restored to convey a good idea of its general features, which are decidedly masculine and even animal- like. * The zygomatic bones being broken, the zygomatic diameter could only be ascertained approximately.
