dent traces of * parieto-occipital' flattening, which has extended above 

 the lambdoid and for a wefl-defined space on either side of the sagittal 

 suture. None of the sutures are complex. Flattening on the left 

 side of the frontal bone is manifest, indicating the direction in which 

 the compressing force has been exercised throughout life. No other 

 abnormal development is visible. The molar and jDremolar teeth in 

 place, show little signs of erosion. The basioccipito-sphenoid suture 

 having been present, the basioccipital bone has been broken away, 

 as well as the right border of the foramen magnum and the right 

 squamosal bone. The maxilla is slightly prognathic. The skull 

 presents the most similarity to the skulls from Canete, in Peru, 

 described by Castelnau, and to some which I have seen from the 

 uplands of the Argentine provinces, near Rosario. 



''2. Broken maxillary (adult?) left side. The first premolar, as 

 well as the broken fragment of the second premolar, are the only 

 teeth which remain. Slight erosion is visible on the crown of the 

 first tooth. 



"3. Lower mandible, left ramus. Thickly incrusted with limonite 

 and sand, which has filled up the alveoli. Only the first and second 

 molars are in place, the second being turned out of its proper inser- 

 tion, as well as the first being much worn. Both the molar teeth in 

 place are much worn on tlie outer side of the teeth. All the other 

 teeth, with the exception of the first premolar, are absent. No 

 marked outward or inward inflection of the angle is present. 



"4. Lower mandible, left ramus. This specimen exliibits the 

 same general characters as No. 3, with the exception that the incrus- 

 tation of limonite is not present. On the inner sides of m. 3 and m. 2, 

 the upper angles of the cusps have been broken away, the whole sur- 

 face of the teeth being much worn. M. 1 is mu»h worn, and a small 

 fracture of the alveolar process outside it has permitted that [sic] 

 the two outer fangs to be elevated and dislocated from their own 

 proper insertions and to form by this dislocation a grinding surface. 

 The fu"st and second premolars, as well as the canine and first incisor, 

 are also much worn. The mental process of the j aw is high ; the genial 

 tubercles distinct; and the mental foramen, not as in No. 3, filled up 

 with limonite. The coronoid process is high; and, although the 

 angle is broken away, enough remains to lead us to conjecture that 

 it was strong and powerful. 



''5. Portions of parietal bones of average thickness, incrusted with 

 ochreous mud. 



"6. Upper part of supraoccipital bone, and lower and posterior 

 portions of two parietals, exliibiting the confluence of the sagittal and 

 lambdoid sutures. The supraoccipital bone is slightly elevated above 

 the level of the lambdoid suture, which, as well as the sagittal, is very 

 complex. There are no traces of wormian ossifications and on the 

 inner side of the bone the sutures are perfectly closed.
