5425. The skull of a modern Peruvian child from the valley of Copyapo, thirty -three 

 leagues from the coast. 



This child has been the subject of chronic hydrocephalus, whereby the cranium has become 

 unusually expanded. The expanded back part of the cranium shows the flattening produced 

 by the resting-board. The alisphenoids ascend to a level with the upper borders of the 

 orbits. The vaginal processes are unusually distinct and prominent. The premaxillary 



sutures remain upon the palate. 



Purchased. 



5426. The skull of a male Patagonian. 



It agrees in general shape with that of the modern Peruvians, Nos. 5422 and 5423, the 

 occiput presenting the same height, breadth, and slight unsymmetrical flattening, but it is 

 distinguished by its superior size, obviously belonging to a larger race of men. The frontal 

 sinuses are well developed. The nasal bones are narrow, but prominent. The malars are 

 large and prominent. The upper jaw is moderately produced.

5427. The cranium of a female Patagonian. 



It has the same general form and large proportional size, but with smaller and more neatly- 

 defined facial bones. The forehead is narrower, lower, and more receding than in the male ; 

 the broad quadrate occipital region is flatter, and bent more abruptly from the superior, almost 

 flattened, parietal region. The vaginal processes are unusually produced. The glabella is 

 prominent : the nasals are long and unusually prominent. The malars are smaller and less 

 prominent than in the male. The upper jaw is moderately produced. This and the pre- 

 ceding skulls were taken from under a heap of stones on the east coast of Patagonia, near 

 Port Melo.

5428. The skuU. 



The cranium is subelongate, moderately expanded at the parietal bosses, with a narrow and 

 protuberant superoccipital : the forehead is narrow and low. The glabella is prominent, and 

 the nasals are produced. The malars are moderately prominent ; the jaws prognathic ; the 

 chin well developed. The base of the skull presents paroccipital protuberances, large styli- 

 form processes of the sphenoid, and small but distinct eustachian processes of the petrosal. 

 Traces of the maxillo-premaxillary suture remain on the palate. The molar teeth are of 

 moderate size, and are worn on the inner border in the upper jaw and on the outer border in 

 the lower jaw.
