384 CRANIA FROM THE MOUNDS OF FLORIDA. 



Yakatat <? . Princeton College. 1 Aged 40 years, — platycephalic. 



Glabella and supra-orbital ridge faint ; supra-orbital margin, 40°. — Nasal bones 

 concave scarcely narrowed at bridge; frontal portion 2 mm., maxillary portion 15 

 mm.; radix 5 mm., 90°; salient 20 mm., 40°. Nasal vestibule microlophic ; incisor 

 eminence nil.; spine double, pantomorphic, with marked ridges; alveolar line 

 discernible. — Alveolus high. — Hard palate parabolic 10 mm. ; choanse pantomorphic ; 

 spinous process scarcely overlapping petroso-sphenoidal fissure. — Foramen lacerum 

 medium open. Petrosa inflated. — Temporal ridges not marked ; parietal bone with 

 mortise at post-squamosa ; occipital squamosa projecting slightly beyond lambda. — 

 Sconce 60 mm. 



Lower Jaw. The third molar in advance of base of coronoid process ; mental 

 foramen between second bicuspid and first molar ; angle everted ; genial spine and 

 ridge both rudimental ; condyloid process massive, angulated ; hyperostosis on inside 

 of lower jaw at premolars. Teeth are much worn, cuspidation obscure. 



Sitka ? . Princeton College. Aged 60 years, — sphasrocephalic ; slightly 

 deformed, much mutilated. 



Glabella and supra-orbital ridge nil. — Palate hyperbolic ; outer half of the 

 supra-orbital border slightly inclined. — Spinous process not overlapping sphenoido- 

 tympanic fissure. Skull "cut-off." 



562 <?, Kocliak, Alaska. Columbia University, New York. 2 Aged 50 years, — 

 globicephalic ; artificially deformed. 



Glabella and supra-orbital ridge rather prominent. — Nasal bones coalesced ; 

 frontal part 3 mm.; maxillary part 15 mm. Narrow saddle moderately depressed. 

 — Nasal vestibule narrow, small, analophic. No nasal eminence or alveolar line. 

 Spine single, prominent, with sharp riclge extending into the chamber; alveolus 

 high. — Anterior wall of maxillary sinus greatly depressed. — Hard palate hyperbolic. 

 — Sphenoido-tympanic fissure greatly overlapped; petrosa not inflated; occiput 

 deformed by softening. Occipital condyles small. — Marginal process of malar 

 moderately developed. Suture- trace marked ; bone enters into spheno-maxillary 

 fissure. The fronto-temporal crest well defined, interrupted from the parieto tem- 

 poral at the stephanion. The parieto-presquamosal suture falls off sharply to near 

 posterior end, where it forms a long mortise on the parietal ; parieto-post-squamosal 

 well defined ; post squamoso-ecto-petrosal suture discernible. — Lambda obliterated ; 

 muscular impression weak ; occiput artificially flattened ; obelial foramina open. 

 — Lachrymal bone small ; lachrymo-planal suture irregular. Hamular process 

 unites with maxilla in orbit ; an ossicle intercalated on right. Skull platybasic, rests 

 on opisthion.

 Permission to examine this and other specimens from Columbia University was courteously 

 extended by Prof. Geo. S. Huntington.
