to be looked on as either an infantile feature or as an example of 

 recession, as is observed in these structures in the most highly civi- 

 lized peoples of the actual time. Under no condition could they be 

 viewed as marks of primitiveness or antiquity. The ridges also extend 

 over only the median half of the supraorbital space, as in the great 

 majority of Indian crania. There is the usual slant of the outer part 

 of the supraorbital region, perhaps in this case slightly augmented 

 by the compression of the forehead, but there is no tendency toward 

 an arch such as characterizes the skulls representing well-known 

 earlier forms of humanity. 



The parietal region is oval from side to side, there being no sagittal 

 crest. The parietal eminences are moderate. The outline of the 

 norma superior approximates to long ovoid, with the narrower end 

 forward. The temporal crests are not well traceable, but evidently 

 ran at a good distance from the sagittal suture. 



The occipital flattening is only moderate yet plainly perceptible. 

 It extends quite high and there is no subinionic depression as in 

 highly misshapen Ayma-ra skulls, but these features are common to 

 the less deformed crania of this type. They are shown by all the 

 fossil-like specimens, as well as by the more recent deformed skull 

 from Viedma and can be seen also on true Aymara skulls (pis. 37-41). 

 It is possible that in these cases there exists a combination of the 

 effects of the compress and the cradle-board. The occipital ridges 

 and impressions also are not very pronounced in the Miramar skull. 



The sutures of the vault, with the exception of the temporo-parietal, 

 are apparently all synostosed, but the condition of the specimen per- 

 mits no exact determination of this nor of the characteristics of the 

 sutures. The naso-frontal articulation is patent, at least to a large 

 extent. The plerions are both of the H form and of medium breadth. 



The facial parts are very defective. The left malar shows no 

 features worthy of special remark. The nasal aperture was appar- 

 ently of medium breadth, as in most Indians. The nasal spine is 

 broken. There are no subnasal gutters or fossae. The upper alveo- 

 lar process was rather low and but moderately prognathic. 



The temporal region (left) is moderately and uniformly convex. 

 The mastoids are broken, the right, which is better preserved, show- 

 ing moderate masculine size. The roots of the zygomae are quite 

 stout. Nowhere in these parts is there any feature that would give 

 the impression of characteristics other than the ordinary in the 

 Indian. 



The lateral angular processes are rather broad, though not abnor- 

 mally so. The diameter between their most distal parts measures 

 10.4 cm. In a male Patagonian (No. 264109, United States National 

 Museum) the measurement is likewise 10.4 cm., while two other skulls
