5408. The skull of a Flat-head Indian, from Coffin Island, Columbia River. 



The styliform process of the sphenoid has become confluent with the ectopterygoid on the 

 right side ; it is unusually prominent on the left. The glabella and nasal bones are in the 

 same oblique line. 



Presented by Copt. Sir Edward Belcher, E.N. 



5409. The cranium of a Flat-head Indian from the same locality. 



From the unusual bulging on the left side, it is probable that some amount of hydrocephalus 

 was produced during the process of compression. Traces of the premaxillary sutures are 



distinct and extensive on the palate. 



Purchased. 



5410. The cranium of a Flat-head Indian from the Columbia River. 



The frontal sinuses and glabella are more prominent than in the foregoing specimens : the 

 suture dividing the frontal has been retained. The calvarium has been detached : the cranial 

 parietes at the line of section do not exceed the ordinary thickness. 



Purchased. 



5411. The cranium, vertically and longitudinally bisected, of a Flat-head Indian, 

 from the Columbia River. 



In the prominence of the glabella it resembles No. 5410, but the frontal suture is oblite- 

 rated, and the parts of the coronal suture below the temporal ridges. In the line of section, 

 the cranial parietes are thinnest at the middle of the flattened frontal, where the diploe 

 is obliterated: the rest of the parietes are thicker than usual. The supramastoid and occipital 

 ridges are well developed. The paroccipital tubercles are distinct. The increased capacity 

 of the hinder part of the cranium compensates for the diminished height of the fore part.

5412. The skull of a female infant of the Flat-head Indian race, from the Columbia 

 River. 



The deciduous incisors have cut the gum : not the deciduous canines or molars. The 

 elements of the occipital are ununited. The superoccipital is expanded, almost flattened, and 

 pushed unsymmetrically to the left side, by the pressure of the lower flattening-board, which 

 has also flattened the lower part of the right parietal : the effect of the upper flattening-board 

 is more remarkably shown upon the frontals and contiguous parts of the parietals : the sutures 

 are linear and the great fontanelle is widely open : the compressed brain has pushed forwards 

 the orbital plates of the sphenoids and frontals, and must have caused the eye-balls to protrude 

 frightfully : the lower border of the orbits is much advanced beyond the upper one. The 

 alisphenoids join the parietals on both sides of the head. The maxillo-premaxillary suture 

 remains on the palate and in part of the nasal cavity. The nasals, malars, and right exoccipital 

 are wanting in this skull.
