Aug. 1897. Observations on Papuan Crania — Dorsev. 21 



slightly worn. The upper right third molar and both lower third 

 molars are suppressed. 



Norma Frontalis. — (See 'PI. V, Fig. 1.) The forehead is small but 

 rounded and fairly prominent, and in proportion to the face seems 

 unusually large. This is owing to the extreme narrowness and short- 

 ness of the face as shown by the bizygomatic diameter of 109 mm., 

 and the nasomental length of only 96 mm. The orbits are of large 

 size, somewhat elongated and measure 40 x 34 mm. There is a very 

 marked inclination to the orbital axes. The nasal bones are sym- 

 metrical and well shaped; the bridge is only moderately acute, there 

 bi ing a tendency at the lower aspect to flatness. Nasal openings 

 rounded, with small spine and incisor crest. The canine fossae are 

 broad and sunken. Alveolar arch short and compressed, the outline 

 of each alveolar cavity being plainly indicated. There is a small 

 foramen on both sides passing into the diploe, just beneath the 

 supraorbital notch. 



Norma Verticalis. — (See PI. V, Fig. 2.) Long and narrow. The 

 cephalic index is 65. Parietal eminences well marked, but not pro- 

 jecting. There is a slight depression on each side just anterior to the 

 eminences. The frontal region is broader than the occipital. 



Norma Posterior. — (See PI. VI, Fig. 1.) Well marked pentag- 

 onal form, with prominent vertex, long almost straight sides and 

 slightly downward curving base. The maximum diameter exceeds 

 the asterionic diameter by only 15 mm. 



Norma Lateralis. — (See PI. VI, Fig. 2.) On the frontal bone the 

 anterior portion of the curve is well formed, but less than half way up 

 the line becomes nearly horizontal until near obelion. There is a 

 slight depression just anterior to bregma, which is the highest 

 point of the vertex. From obelion the curve takes a rapid downward 

 course to a point about 15 mm. above inion. From inion to opisthion 

 the line is nearly horizontal. There is a slight depression at nasion, 

 and considerable facial prognathism, with an unusual amount of 

 alwolar prognathism. The temporal suture is not highly curved. 

 Left pterion in K. Right temporal is removed from the frontal bone 

 by 6 mm. 



Norma Inferior. — (See PI. Ill, Fig. 2.) Foramen magnum is 

 slightly rounded and is rather larger than one would expect in a skull 

 of this capacity; measures 33 x 30 mm. Just anterior to basion and in 

 a median line is a well formed third condyle. It is about 6 mm. in 

 height and 7 mm. in breadth. The condyle of the left side is 4 mm. 

 farther forward than that of the right side. The palate is long and
