370 CRANIA FROM THE MOUNDS OF FLORIDA. 



break only between pre-squamosal and post-squamosal portions. — Scarcely any 

 flange at end of temporal ridge. — Occiput not protuberant, inion marked ; no break 

 in occipitoparietal curve, i. e., curve of obelion continuous with that of supra-inion. 

 The skull rests on the posterior border of the foramen magnum, i. <?., the concep- 

 tacula cerebelli are small. — Malar bone with conspicuous marginal process and 

 suture-trace. — Sconce smooth, scarcely pitted, 122 mm. wide; highest point back of 

 bregma ; obelion with foramina. 



Lower Jaw. The condyloid process inflated, scarcely angulated, the lateral 

 facet two-thirds inclined downward, the median facet one-third. Third molar in 

 advance of coronoicl ; high alveolus, no trace of bicuspid hyperostosis. Masseteric 

 impression concave, the angle scarcely inclined outward, on right side ; mental 

 foramen between second premolar and first molar, on left side on line of second 

 premolar; genio-glossus spine single, prominent, crest small but defined. Teeth 

 much worn. Upper third molar in position. 



No. 1,784 bears a close resemblance to No. 1,782. 



1,782 L S (Pis. L1II, LIV, LY, LVI, LVII). Aged 50,— sutures closed, excepting 

 about squamosa ; globular, archencephalic inclined to phoxocephalic. Greatest 

 transverse diameter bi-squamosal. 



Glabella and supra-orbital ridges marked, 6 mm. ; upper half of frontal bone 

 showing median elevation ; forehead broad, ample ; sutures closed in outer wall of 

 orbit. ; outer part orbital arch scarcely inclined downward, 25°. — Nasal bones 

 synostosed, abruptly arched, projecting, concave from above downward ; frontal 

 part nil ; maxillary part 25 mm. ; premaxillary part 2 mm. ; radix 6 mm., 80° ; 

 salient 19 mm., 20°. Nasal vestibule microlophic with incisor eminence small, 

 oblique ridge to spine present ; alveolar line produced slightly beyond the ridge but 

 inconspicuous ; spine single and incisor crest marked ; prenasal fossae rudimeiital. 

 — Alveolus high ; inter-premaxillary suture not produced. Small pretorus. — Hard 

 palate U-shaped, almost parabolic, no anterior inclination, alveolar height 13 mm. — 

 Spinous process overlapping petro-sphenoidal fissure ; petrosa inflated ; alse of vomer 

 below plane of presphenoid ; foramen lacerum medium open. Temporal ridge every- 

 where distinct, interrupted at stephanion 26 mm. ; no trace of coronal, fronto-sphe- 

 noidal or parieto-sphenoidal sutures ; parie to-temporal crest heavily moulded, 

 projecting posteriorly making parieto-occipital suture harmonic near asterion ; no 

 break between post-squamosa and ecto-petrosa. Occiput abruptly narrowed from 

 the side ; supra-occipital thickened, but no break in the occipito-parietal curve ; 

 skull rests on posterior border of foramen magnum. — Sconce rugose, much pitted, 

 100 mm. wide; sagitta carinate at bregma. 



Lower Jaw massive ; third molar in advance of base of coronoid process ; 

 masseteric impression scarcely concave, angle but slightly inclined outward ; pre- 

 gonial tubercle large ; condyloid process thick, everywhere inflated, no division 

 into facets, the inner part inclined downward ; on the left side mental foramen
