The vault of the skull is reconstructed in part, but Lehmann- 

 Nitsche has full confidence that the reconstruction is accurate. The sex 

 of the individual he judges to be feminine. The thickness of the bones 

 is ordinar}^. On account of the defective condition of the specimen 

 only a limited number of measurements is practicable. The norma 

 frontalis "offers, so to speak, no noteworthy feature." The front 

 appears narrow, the parietal eminences are pronounced. The skull 

 is very long and relatively narrow; the cephalic index is calculated as 

 71.1. Both dorsally and ventrally the occipital bone shows nothing 

 in common, with the exception of a deep cerebral fossa, which js 

 "extremely remarkable." "The norma basalaris offers notliing 

 particular." The norma lateralis shows somewhat prominent supra- 

 orbital arches and a deep nasion depression. The frontal curve is not 

 pronounced. The skull is very high. The capacity of the skull is 

 calculated as 1,528 cc. The lower jaw shows "very pronounced 

 human characteristics," the ascending ramus is narrow, the angle 

 wide. It is notable by the prominence of the chin. Nothing out of 

 the ordinary was discovered in the curve of the body. "It represents 

 absolutely the recent European type. The teeth are small." 



As to the fragments of the long bones, that of the right humerus is 

 robust. The radius was veiy powerful and only slightly though regu- 

 larly curved. The rib presents no special features; its "constitution 

 indicates an individual of a stature above the medium and very 

 vigorous."

In 1910 the Chocori skull was briefly examined by Mochi and is 

 reported on in his paper on Argentine paleo-anthropology.^ It was 

 found to be dolicho- and chamaecephalic. The norma superior is 

 pentagonoid. As to sex, the author is inclined to consider it mas- 



1 Lehmann-Nitsche does not express directly Ms notion of the age of the Chocori sli:e!eton, but, as on 

 p. 300 of his Nouvelles recherches, etc., he considers the Arrecifes skull "seemingly the most recent" 

 of those dealt with in his work, it is e\ident that he regards the Chocori specimen as more ancient. His 

 statement on p. 321 that "the Chocori bones are completely identical in character" with those of fossil 

 animals from the Pampean formation — a statement somewhat at variance wath certain ^iews of Ameghino 

 and Roth, as well as ^vith the wTiter's observations — points in the same direction. Finally, in his most 

 recent publication (El hombref6sil pampeano) he classes the slaiU with those of Arrecifes, Miramar, etc., 

 as belonging to the Superior Pampean formation, which he regards, with the exception of its uppermost 

 parts, as Quaternary.
