400 CRANIA FROM THE MOUNDS OF FLORIDA. 



mortise at post-squamosa ; squamosa 40 mm. high ; sagitta carinate. — Small lachry- 

 mal bone, hamular process uniting with maxilla ; small posterior marginal process, 

 os planum 8 mm. high. 



Lower Jaw. Angle slightly deflected ; condyloid process angulated ; third 

 molar in advance of the coronoid process. Spine prominent, crest nil. Mental 

 foramen on line of second premolar. A powerful form of jaw. The entire skull 

 massive and recalling forcibly the South Sea type. Upper molars 4—4—3 ; lower 

 molars \ \°\. 



1,815 ?, aged 35 years, — cymbecephalic. 



Glabella and supra-orbital riclges nil. Superior orbital margin slightly inclined, 

 40°. — Nasal bone broad low arch, depressed radix 5 mm., 90° ; salient 13 mm., 50°. 

 Nasal vestibule microlophic without classifiable characters ; incisor eminence high, 

 alveolar line faint, obscuring small fossa. — Hard palate scarcely parabolic, shallow, 

 11 mm. — Sphenoido-tympanic fissure not overlapped by the spinous process. — 

 Petrosa not inflated. — -Sides of choanse greatly inclined, 80° ; wider at base than 

 apex. — Lambdoidal suture serrate near asterion. — Malar bone with small marginal 

 process ; enters spheno-maxillary fissure ; suture-trace present. Bone narrow for- 

 ward. — The hamular process of the lachrymal bone joins the maxilla. — Skull rests 

 on opisthion ; phrenozygomous. — Sconce 110 mm. 



1,819 $ , aged 45 years, — archencephalic ; oval, well filled. 



Glabella with trace of metopism, supra-orbital ridge very large, 3 mm. — Nasal 

 bones 25 mm. ; frontal part 2 mm. ; bridge low ; radix G mm., 90° ; salient 16 mm., 

 20°. — Nasal vestibule microlophic; incisor eminence and spinal crest rudimentary; 

 alveolar slim, line discernible. — Hard palate parabolic, alveolar process 15 mm. ; 

 choanse peedomorphic ; pyramidal process produced ; petroso-sphenoidal fissure 

 greatly overlapped. — Petrosum on left side inflated. — Post-bregma carinate, bregma 

 elevated. — Temporal impression markedly developed. Lambdoidal suture serrate 

 near asterion. — Malar bone small, 20 mm. wide at narrowest part. Inner surface 

 with suture-trace ; marginal process conspicuous ; bone does not enter into spheno- 

 maxillary fissure. Skull rests on conceptacula ; phamozygomous. 



Glabella and supra-orbital ridge conspicuous, especially at the beginning of 

 the last named, but the actual projection of the first named small. The prominence 

 on the malar bone extraordinarily developed. The nasal salient of remarkably low 

 degree, 20°. The parieto-sphenoidal suture but 5 mm. long. 



1,824 <?, aged 45 years, — archencephalic. 



Glabella and supra-orbital ridge moderate ; superior orbital margin greatly 

 inclined, 30° — Nasal bones asymmetrical, broad 9 mm., long 20 mm.; frontal por- 

 tion 2 mm.; maxillary portion 15 mm.; premaxillary portion 6 mm. — Nasal vestibule 

 analophic ; incisor eminence moderate ; spine and spinal line well defined ; alveolar 

 line nil; alveolus moderate, 14 mm. — Hard palate hyperbolic, alveolar height 20
