Aires. One carapace of a Glyptodon, nearly complete, was found, 

 Burmeister says, only 1 foot below the surface of the ground. 



"The human skeleton was found buried in this unmoved deposit 

 of loess, at a depth of 1.80 meters from the surface oP the ground, 

 deeper than many remains of Glyptodon, Sderocalypus, Eutatus, etc., 

 which we have collected in the same locality. 



"The skeleton consists of a skull, of which the lower jaw and the 

 facial parts are missing, and of various long bones, numerous ver- 

 tebrae and ribs, the sacrum, the pelvis, and a number of the bones 

 of the feet, among them a nearly intact astragalus. 



"The long bones indicate that the individual was still young; 

 compared with those of the actual man, they would correspond to one 

 of 16 to 18 years of age. Moreover, it was an individual of very 

 reduced stature, probably not greater than 1.40 meters. 



"The bones of the skeleton present very notable peculiarities, of 

 which for the present I shall mention only the superficial form of 

 the 'ectal' articular facet oi the astragalus, which is not deeply 

 concave as in actual man, but much flatter; and the form of the 

 femur, whose linea aspera is scarcely visible, and which presents 

 toward the middle of its length a nearly circular transverse section, 

 like the femur of many apes. 



"The skull is excessively small and very dolichocephalic. . . , [*] 



"It is very low anteriorly and excessively high posteriorly, so 

 that the vertex falls far back of the bregma, more or less in the pos- 

 terior two-thirds of the parietals, in which characteristic the skull 

 coincides with the Homo jmmpaBUs. 



"I have not measured the cranial capacity, but I calculate that it 

 does not surpass 1,000 c. c. 



"Posteriorly there is no torus occipitalis, the inion region is not 

 prominent but rounded and all the muscular insertions are but little 

 developed. 



"The sutures, including the lambdoid, are exceedingly simple 

 and nearly straight. The mastoids are very small. The fi'ontal 

 region, much depressed, rises gradually toward the back, and the 

 vault continues to rise in this way up to the vertex. 



"The fron4^al bone is very j^rominent by reason of its elongated 

 and narrow form, in which it presents a remarkable similarity to 

 the formation proper to the Diprothomo. In a straight line, with- 

 out paying regard to the curve, it measures 106 mm. in antero- 

 posterior, and 98 mm. in its greatest transverse diameter. The 

 post-orbital narrowing is very slight, the minimum transverse diam- 

 eter at this point being 91 mm., only 7 mm. less than the maximum 

 transverse diameter.
