378 CRANIA FROM THE MOUNDS OF FLORIDA. 



7 mm., 40°. — Nasal vestibule analophic with incisor eminence raised nearly to the 

 top of the small incisor crest. The spine is connected with the incisor eminence by 

 trenchant ridges, alveolar line rudimentary. — Alveolus 18 mm. — Hard palate hyper- 

 bolic, alveolar process 15 mm. ; choanse, base wider than apex. — Foramen lacerum 

 medium open ; spinous process enormous, overlapping sphenoido-tympanic suture ; 

 petrosa inflated. — The temporal ridge interrupted at the stephanion 19 mm. ; lamb- 

 doiclal suture near asterion harmonic. — Malar bone with marginal process ; suture- 

 trace present. — Sconce 86 mm. wide. 



Lower Jaw. Third molar in advance of base of coronoid process. Lateral 

 facet of condyloid process much worn, median scarcely inclined ; mental foramen 

 on line of second premolar right and left. Genial spine and genial crest slightly 

 developed. The skull rests on basion and opisthion ; the curve from opisthion to 

 transverse occipital torus unbroken ; a second curve from the torus to the inter- 

 tubera is entire, though the obelion is slightly depressed. — Upper molars 4-4-3 ; 

 lower molars \° \% 



1,840 $ , aged 40, — phoxocephalic. 



Glabella and supra-orbital ridge faint not measurable ; supra-orbital margin 

 40°. Nasal vestibule macrolophic, alveolar line subtrenchant ; crest ending on 

 simple produced spine. — Alveolus short, 15 mm. — Hard palate parabolic deep, 

 alveolar height 13 mm. — Spinous process large ; but scarcely overlapping fissure ; 

 tegmen enormous. — Foramen lacerum medium open. — Malar bone with large mar- 

 ginal process ; suture-trace present. — Temporal crest not interrupted at stephanion, 

 while the lambcloiclal suture is harmonic near asterion. — Upper molar 4-4-0. — 

 Skull rests on the conceptacula. The curves of the brain-case disjunct, the 

 opisthio-inion, the supra-inion and the lambdo-intertuberal being separate. The 

 lambda and obelion are depressed, thus constituting the " cut-off" skull. 



604 <?, aged 45, — coronal and sagittal sutures obliterated, — phoxocephalic. 

 Slightly deformed, the right parietal bone being more convex than the left. 



Glabella and supra-orbital ridge, 3 mm.; outer part orbital arch, 40.° — Nasal 

 bones scarcely convex, depressed; frontal portion nil; maxillary portion 25 mm.; 

 premaxillary portion 5 mm. ; radix 9 mm., 80° ; salient 21 mm., 30° ; ascending 

 process of maxilla transverse to plane of inner wall of orbit. Nasal vestibule analo- 

 phic ; incisor eminence discernible with faint alveolar line and fossa ; spine simple, 

 crest none; the entire vestibule, therefore, paedomorphic ; alveolus small, 15 mm. 

 — Hard palate hyperbolic ; choanae, base broader than apex. — Foramen lacerum 

 medium almost closed. — Pterygo-spinosal junction. — Enormous spinous process 

 uniting with tegmen and overlapping sphenoido-tympanic suture. — Petrosa inflated. 

 — Malar bone with large marginal process, and marked suture-trace ; bone enters 

 spheno-maxillary fissure. — Lachrymal bone sutures between os planum and maxilla 

 obliterated. — Temporal ridge well developed ; no interruption at stephanion, but the 

 second stadium of the ridge as well developed on the frontal as on the temporal
