There are no subnasal grooves or fossae. The prognathism is 

 medium, again as in Indians. The suborbital (canine) fossae were 

 apparently shallow. The malars and zygomae are of ordinary form 

 and female dimensions. 



The palate is fairly but not excessively deep, and the alveolar arch 

 measures (by Turner's method) about 5.2 cm. in length and 6.4 cm. 

 in breadth. 



Dentition as well as the teeth was normal. The latter are of 

 feminine size; their other characteristics are obliterated by wear. 

 The crown of the third lower molar on the right side appears to be 

 slightly longer than that of the second but the breadth is the same; 

 above, the third molars were smaller than both the second and the 

 first. 



The lower jaw is entirely Indian in form. The prominence of the 

 chin is well-marked. Height at symphysis, about 3.7 cm., anterior 

 to the second right molar, 3.4 cm.; thickness opposite second right 

 molar (at right angles to the vertical axis of the ramus), 1.25 cm. 

 The height is unusual if the skull is that of a female, but lower jaws 

 with high symphysis are particularly common in modern cranial 

 material in eastern Argentina from the Parana to Tierra del Fuego. 



Additional Homo pampseus specimens from Nechochea. — Besides the 

 defective skulls noted in the preceding pages, there were found in 

 Professor Ameghino's collection at the Museo Nacional in Buenos 

 Aires, under the number of one of the skulls (5004), various frag- 

 ments of a skull (the fourth example of Homo pampseusf) and bones, 

 all in poor condition for examination, broken and eroded. They are 

 all whitish-gray or yellowish-brownish white in color and possibly 

 somewhat aUered in their mineral composition. 



The pieces include part of the left clavicle of a child. There are 

 also several remnants of long bones which show disease, the lesions 

 resembling very closely syphilitic alterations and scars; a portion 

 of a femur presents also a thickenmg of the shaft. The pathologic 

 changes are in the main of the same character as those seen in skull 

 No. 5004, and the bones are in all probability part of the same 

 skeleton. 



The fragments indicate an individual of moderate stature and 

 muscular development; anatomically none of them shows any 

 characteristic at all which could be considered out of the ordinary. 



This is all worthy of mention that the writer found in these 

 earlier Necochea specimens, and it surely fails to substantiate the 

 existence of anything so important as a separate species of man, a 

 Homo pampseus. 



Necochea slceleton (No. 263966 TJ. S. National Museum) .—This 

 skeleton is represented by about 150 fragments, the largest of which 

 are (after repair) a portion of a humerus, 16.5 cm., and a piece of a
