Aug. 1897. Observations on Papi an Crania — Dorsev. 15 



Genio-glossal spine double; genio-hyoid crest very small. The stylo- 

 hyoid ridge is heavily marked, especially that portion just under tin- 

 first molars. Height of symphysis 31 mm.; mandibular angle 130°. 



NO. 40,595. — Skull of an adult male. Teeth all present in per- 

 fect condition, with no sign of wear. Cranial capacity, 1,390 cc. 



Norma Frontalis. — (See PI. IV, Fig. 1.) Glabella and super- 

 ciliary ridges prominent. Orbits slightly rounded, with a very slight 

 inclination of the axes. Interorbital space medium. There is pres- 

 ent on both ridges the infra-orbital suture. The nasal bones are small, 

 well-shaped and form a projecting bridge; the nasal openings are 

 fairly sloping with but little nasal spine. The canine fossae are deep, 

 almost cavernous. Malars and zygomatic arches projecting, but total 

 face is long and narrow, especially in the region of the jaws. 



Norma Verticalis. — The skull is long and narrow and of regular 

 outline, owing to the slight development of both frontal and parietal 

 eminences. Cephalic index, 65. Bizygostephanic index, 87. 



Norma Posterior. — Pantagonal form with broad bas,e and sides 

 and rather angular at vertex. 



Norma Lateralis. — (See PI. IV, Fig. 2.) Well-mafked frontal 

 development: the curve of the vertex is graduar to obelion, where it 

 passes rapidly down to inion, there it becomes almost a straight 

 line to opisthion. The frontal external angular process is thick and 

 heavy. The glabella overhangs nasion to a considerable extent; 

 alveolar prognathism marked. 



Norma Inferior. — The foramen magnum is nearly circular, 31 x 28 

 mm., except on leftside, where the posterior condyloid foramen is 

 continuous with the foramen magnum. On the right side the jugular 

 process has grown over and covers the petro-occipital synchon- 

 drosis. 



Sutures. — The coronal and lambdoidal are very simple; the 

 sagittal is slightly more complex. There is a long, narrow wormian 

 bone, 25x4 mm., at right pterion; also a small wormian bone just 

 above right asterion. 



There can still be made out a cleft, 11 mm. in length, starting 

 just above left asterion and extending in the direction of inion; a 

 somewhat similar cleft, but not so distinct, exists also on the right 

 side. 



Processes. The mastoids are very rough and of large size, 

 although not long. The styloid processes are large and thick, and 

 are protected by the vaginal sheath for a distance of about 15 mm.
