392 CRANIA FROM THE MOUNDS OF FLORIDA. 



opposite second premolar ; angle incurved. Slight alveolar hyperostosis opposite 

 premolar and molar. Third molar in advance of coronoid process. 



This is a remarkable skull in many respects. The closed foramen lacerum 

 medium, the level palatal aspect of the premaxilla, the rudimental incisor crest, the 

 parabolic hard palate and the occiput at the transverse torus projecting beyond the 

 inion, are all pa?domorphic characters. The skull is also veiy fiat and slightly 

 artinciall}" deformed on the left side of the occiput, The absence of the marginal 

 process of the malar bone and of the vaginal process about base of the styloid 

 process would denote the sex to be female, yet the forehead is not rounded, and the 

 temporal fossa is unusually prominently marked at the stephanion and near the 

 lambdoidal suture. 



566 <?, "Digger," California. 1 Aged 45 years, — archencephalic. 



Glabella and supra-orbital ridge prominent, 5 mm. ; outer half superior orbital 

 margin inclined outward and downward. External angular process of the frontal 

 bone thickened, but this thickening is independent of the supra-orbital ridge. — Fore- 

 head ample, with metopic elevation. — Nasal bones mutilated, but anterior nasal 

 aperture narrow. Nasal vestibule microlophic ; incisor eminence and alveolar line 

 almost nil. Spine single, prominent, with lines extending into chamber to incisor 

 eminence. — Alveolus 13 mm. — Hard palate hyperbolic. Alveolar process 16 mm. — 

 Pretorus present ; pyramidal process small. Sphenoido-tympanic fissure overlapped 

 by spinous process on right side only. — Petrosa moderately inflated. — Front o-temporal 

 ridge faint. Crest between it and the parietotemporal at stephanion. The posterior 

 part at lambdoidal suture pronounced and heavily moulded. Sagitta carinate. 

 Auditory passage with exostosis, most marked on the left. — The malar bone with 

 large marginal process ; the bone enters spheno-maxillary fissure ; the suture-trace 

 present. In the lachrymal bone the hamulo-maxillary union present. The skull 

 rests on the opisthion. — Sconce 92 mm. 



The lower jaw is massive ; condyles mutilated ; third molar in advance of the 

 base of coronoid process ; the mental foramen between the premolars. Genial 

 spine double and, together with the genial crest, rudimentary. 



It would be difficult to accept this skull as a member of the same group with 

 No. 565 if a similar contrast had not been noted in the Shoshoni. In the narrow, 

 yet prognathic premaxilla (10 mm.) a resemblance is seen between it and the skull 

 just named, while the general character of the bone is distinct. 



1,835 <?, California. Presented by George Davidson. Aged 40 years, — 

 stenocephalic. 



Glabella and supra-orbital ridge very large, 4 mm. — Nasal bones mutilated; 



frontal portion nil; bridge narrowed; radix 6 mm., 80°; salient 15 mm., 40°, 



slightly carinate. — Nasal vestibule microlophic; nasal eminence nil; spine mutilated; 



spinal crest sharply limited with small fossa. — Alveolus 18 mm. high. — Hard palate
