himself. They have the same dry, spongy constitution and they are 

 very fragile, very friable. All are of a dark-yellowish color. Some 

 of the bones, as for example the humerus, are covered with character- 

 istic calcareous incrustations, which adhere strongly and can not be 

 separated without taking with them the surface of the bone. Besides 

 this, the detailed description which Roth published about his discovery 

 and which he personally repeated to me, has convinced me fully of the 

 contemporaneity of Glyptodon with the man of Fontezuelas." 



The results of Lehmann-Nitsche's examination of the specimens are 

 in the main as follows : 



The description and measurements of Hansen, so far as they go, 

 are correct. The basal parts and also the occiput show slight post- 

 humous depressions. The facial parts also have been altered by 

 pressure. Besides the posthumous compression, Lehmann-Nitsche 

 believes there is a slight posterior artificial flattening. 



The skull is dirty yellowish-gray in color and the bone adheres 

 strongly to the tongue. The parietal region shows some calcareous 

 incrustations. The cranium is very large and massive, its external 

 form suggesting decidedly that of the modern Tehuelche skulls. 

 The details concerning the external characteristics of the vault show 

 no remarkable features. 



As to sex, it is not unlikely that it is feminine.^ The lower jaw, 

 however, suggests a male rather than a female. It is very robust 

 and massive and its body is voluminous; the ascending rami are 

 nearly vertical but not particularly broad. The surface of the bone 

 is covered with calcareous incrustations. The inferior outline of the 

 jaw is angular, the chin part being square. The prominence of the 

 chin is seen to be fairly developed. 



The teeth in general are large ; they are very much worn ^ and in 

 the manner observed among the modern Indians of South America. 



Measurements of the lower jaw of Fontezuelas 



Length from right condyle (middle of the posterior border) to the antero- 



superior border of the symphysis (the condyle is somewhat damaged), at cm. 



least 11. 



Height of the ascending ramus, from the inferior border to the notch, in a direc- 

 tion parallel to the posterior border 5. 2 



Breadth of the ascending ramus, perpendicular to the preceding measurement ^. 3. 7 



Height at symphysis 3.3 



Maximum thickness at symphysis (without internal spine) 1. 7 



Thickness of horizontal ramus between second and third molars 1. 6 



Angle (bigoniac) 115° 



1 A skull of such size, particularly if belonging to a short skeleton, with lower jaw, zygomae, and mas- 

 toids as present in this specimen, can more safely be regarded as masculine. The strength of the humerus 

 and the narrowness of the greater sciatic notch make the identification of the skeleton as that of a male 

 quite definite. — A. H. 



2 The size of the teeth, ignoring extremes, can not be judged with any degree of certainty when the 

 crowns are worn off in an advanced degree. — A. H.
