rounded and rather narrow. The forehead is narrow and slopes with a gentle curve directly from the 

 interorbital space, which is more prominent than the supraciliaiy ridges and has no median vertical 

 impression. The alisphenoid presents a margin of half an inch in length to join the parietal on both 

 sides of the head. The cheek-bones and lower border of the orbit are moderately prominent : the 

 nasal bones are continued with a very slight depression from the glabellar prominence : the superior 

 maxillary bones are produced : the lower border of the malar process of the maxillary bone is slightly 

 concave. The lower border of the orbit is a little more concave than the upper one : the spheno- 

 orbital fissure is widely open anteriorly. The cranium of the Macusi Indian (No. 5405) is more 

 oblong and ellipsoid, viewed from above : the forehead is broader, the parietal region narrower, or at 

 least not broader, than it is in the shorter crania of the Carib tribe. The frontal sinuses cause the 

 superorbital ridges to project beyond the interorbital space : the malar bones are equally prominent : 

 the outer angle of the malar processes of the maxillary bones overhangs the concave line leading 

 thence to the alveolar processes. The general character of the facial part of the skull resembles that of 

 the Patagonian Indian, but the prominent convex occiput and general form of the cranium approach 

 nearer to the Carib form. 



The Carib, Guianian and Columbian skulls all agree in the roundness or convexity of the occipital 

 region, and differ in this respect, as well as their more symmetrical figure, from the skulls of the Peru- 

 vians, Chilians and Patagonians. 



All the American skulls manifest the same inferiority in the size of the true molar teeth as compared 

 with the skulls of the Australians : the incisors, canines and premolars, or bicuspides, are not smaller 

 than in the Black races. 



The following, to No. 5472 inclusive, are parts of the same skeleton of a male Esquimaux :

 5442. The skull. 



The cranium is of the long and narrow type, with the parietal protuberances slightly 

 marked. The glabella is not prominent, nor is the supraciliary ridge, which is neatly defined. 

 The malars are large, inclining outwards as they descend : the malar processes of the maxil- 

 lary are almost plane anteriorly. The nasals are large and prominent : the jaws are much 

 produced : the chin is moderately developed. Traces of the maxillo-premaxillary suture 

 remain on the palate. 



This skull differs from those of the Greenlanders (Nos. 5479, 5480), in the smaller 

 size and less prominence of the malars and malar processes of the maxillary, in the minor 

 breadth of the lower jaw, and in the greater development of the prognathic character. 

 The sides of the calvarium slope rather less abruptly from the median elevation than in 

 No. 5479. 



5443. The atlas. 



It differs from that of the male Australian (No. 5186), in the larger relative size of the 

 zygapophyses.
