CRANIA FROM THE MOUNDS OF FLORIDA. 391 



Lower Jaw. Condyloid process much wider on right than left, where it is not 

 angulated. The left angle is also the weaker and more deflected. Spines double 

 almost niL no genial crest. The space above the genial spines is pitted ; between 

 this pit and the alveolus the bone is convex, thus forming an exceptional variation 

 and recalling the primitive form of the bone. Teeth much worn, jaws nearly 

 edentulous. A characteristic small skull. The forehead unusually convex. Slight 

 artificial deformation of the parietal bone back of intertubera. 



\-' 



1,833 <?. Apache. Pecos River, New Mexico. Aged 50 years, — archencephalic. 



Glabella and supra-orbital ridge scarcely discernible. Supra-orbital margin 

 inclined, 30°. — Nasal bones nearly co-ossified ; frontal portion 4 mm.; maxillary 

 portion 21 mm. ; premaxillary portion 3 mm. ; radix 8 mm., 80° ; salient 19 mm., 

 50°. — Nasal vestibule macrolophic. — Hard palate hyperbolic, left most oblique. 

 Alveolar process 11 mm. — Spinous process not overlapping spheno-tjmipanic fissure. 

 — Choana? wider at base than at apex. — Petrosa inflated. — Temporal crest without 

 break at stephanion. — Parieto-temporal porcellaneous near asterion, harmonic. — 

 Malar bone with marginal process moderate ; open in sphenoido-maxillary fissure ; 

 no suture-trace. — Sconce 106 mm. — Skull rests on opisthion. The skull is modern 

 in appearance, and is unusually heavy. 



565 $ , Shasta Co., California. 1 Aged 30 years, — cymbecephalic. 



Glabella small, supra-orbital ridges faintly marked, yet measures from ophryon 

 4 mm., owing to the receding type of forehead. — Nasal bones depressed at middle 

 third ; frontal portion 1 mm. ; maxillary portion 20 mm. ; premaxillary portion 2 

 mm.; radix 9 mm., 70°; salient 13 mm., 10°. — Nasal vestibule analophic ; the 

 incisor eminence nil, alveolar line faint ; the spine obtuse. — Hard palate parabolic ; 

 choanae wider at base than apex. The pyramidal process small ; the foramen 

 lacerum medium obliterated ; the spheno-petrosal fissure not overlapped by the 

 spinous process ; the petrosa not inflated. — The foramen magnum small. General 

 appearance of the occipital bone irregular, narrow and asymmetrical. — Fronto-tem- 

 poral ridge faint, an enormous break at stephanion ; parieto-temporal also faint, but 

 posterior part heavily moulded. Parieto-postsquamosal suture differentiated from 

 the parieto-presquamosal. Serpiginous portion of ectopetrosal with numerous grooves. 

 Most prominent part of the occiput the large transverse occipital torus. — Sconce 120 

 mm. — The skull rests on conceptacula. — Malar bone intact only on the right side. 

 No marginal process, bone enters into spheno-maxillary fissure ; suture-trace present. 

 Lachrymal bones are small, symmetrical. — Hamular process uniting with maxilla. 

 — Middle turbinals inflated, symmetrical. Bulla ethmoidalis rudimental ; palatal 

 bone in nasal chamber inflated. 



Lower Jaw. Condyloid process present only on right ; it is well worn on 

 lateral half. Single large genial spine and small genial crest. Mental foramen 



1 Columbia Univ. Med. Dept. The left condyloid process, right coronoid process and the # 

 right zygomatic arch wanting.
