Aug. 1897. Observations on Papuan Crania — Dorsey. 17 



thirds of the sagittal curve is rapidly downwards to near lambda, just 

 above which is a depression. There is a bulging of the occipital 

 squama between lambda and inion; below inion the curve is rapidly 

 forward, forming an almost horizontal plane. The superior curved 

 line projects about 5 mm. in profile. 



Norma Inferior. — The foramen magnum is diamond shaped, with- 

 diameters of 34 and 32 mm., and looks directly downward. The 

 right jugular fossa is unusually large. The palate is shallow and 

 U-shaped. 



Sutures. — The sutures are all simple, especially the coronal; 

 this suture is almost obliterated below stephanion. The sagittal 

 and lambdoidal are partially synostosed. There is a very large 

 wormian bone in both left and right lambdoidal sutures near lambda, 

 one at left asterion and two at right asterion. The spheno-parietal 

 suture on the left side is 17 mm. in length; on the right side it is 

 14 mm. 



Processes. — Mastoids small; the external occipital protuberance 

 is expanded laterally into a torus occipitalis transversus of the most 

 pronounced type. 



Muscular Impressions. — Not heavy; ^as a rule the surfaces are 

 smooth. There is, howeveif,.'ja r yery broad indented surface for the 

 origin of the masseter. 



Mandible. — Of weak development and of large dimensions to 

 correspond to the large inferior expansion of the face, but the body 

 and ramus are small. The mental protuberance and tuberosities are 

 small. Height of ramus 31 mm. 



NO. 40,618. — Skull of adult male. Cranial capacity, 1,415 cc. 

 The left incisors and canine teeth have been lost; their alveoli are in 

 perfect condition. The third molars have never erupted either above 

 or below, otherwise the teeth are perfectly sound and show no trace 

 of wear. Lachrymals and interior nares destroyed. 



Norma Frontalis. — Long narrow face with retreating forehead 

 and slight development of the frontal eminences. Glabella rounded 

 with faint supraorbital ridges; orbits squarish; narrow, long nasal 

 bones, with only slight convexity but sharp nasal bridge; spine small, 

 incisor crest prominent and openings of anterior nares rounded. 

 There is present on both sides the infraorbital suture. Canine fossa 

 elongated, but not deep; alveolar process short and prognathic. 



Norma Verticalis. — Ovoid, prominent parietal eminences, with 

 minimum frontal diameter of 93 mm., and bizygostephanic index 

 of 69.
