more than the usual female proportions, but its small capacity and 

 absence of muscular impressions incline me to consider it the skull of 

 a female, and in the table of measurements it has been so placed. 

 Cranial capacity, 1,275 cc. The teeth present are in perfect condition 

 and but very slightly worn; the following have been lost: upper and 

 lower left lateral incisors and canines. The interior nares have not 

 been damaged in- the tying of the jaws. 



Norma Frontalis. — The frontal region is narrow, the minimum 

 width being 87 mm. The orbits are nearly square, with narrow infra- 

 orbital space. There is present the infraorbital suture on both 

 sides. The nasal bones are long, narrow and not flattened; nasal 

 opening is slightly rounded, and the spine is poorly developed. The 

 maxillaries are high and compressed; deep canine fossae. The gen- 

 eral shape of the entire face is long and narrow. The malar tuberosity 

 is but faintly indicated, and the zygoma are contracted. 



Norma Verticalis. — Strongly ovoid, due to excessive development 

 of parietal eminences; posterior region narrows rapidly but is pro- 

 longed backwards toward the upper occipital squama. Frontal 

 region narrow. Phsenozygous. 



Norma Posterior. — Irregularly pentagonal, owing to asymmetri- 

 cal development of the parietal eminences, that of the right side being 

 higher up than that of the left. The sides are nearly straight, and 

 there is only 28 mm. between the maximum breadth of the skull and 

 the asterionic diameter. 



Norma Lateralis. — The curve of the vertex is gradual from gla- 

 bella to near ophryon, where it passes rapidly downwards to inion 

 and thence forward. Glabella and inion show plainly in profile, but 

 there is scarcely any superciliary development. The frontal eminences 

 are not well marked; the parietal eminences are better marked and 

 are in the plane of the maximum width. There is but little alveolar 

 prognathism. 



Norma Inferior. — Foramen magnum almost circular in shape, 

 measures 30 x 27. The right petrous bone is defective at the apex, so 

 that the foramen lacerum appears as a long slit-like opening which 

 is continuous with inferior opening of the carotid canal. The pos- 

 terior condyloid foramina are absent. The right jugular fossa is of 

 exceptional size. 



Sutures. — The sutures are all simple, especially the coronal, 

 which is almost a straight line. The coronal contains two wormian 

 ossicles in its left side, and there is a small epipteric at left pterion. 



Processes. — Mastoids of medium size. Styloids very insignificant. 

 The external pterygoid plates are very broad and triangular in
