CRANIA FROM THE MOUNDS OF FLORIDA. 393 



highly hyperbolic; alveolar process 13 mm. high; external pterygoid plate wide. 

 Spinous foramen imperfect. Spinous process not overlapping spheno-tympanic 

 suture. — Choanse very broad at base. — Malar bone mutilated, but enters spheno- 

 maxillary suture ; suture-trace present. — Lachrymal bone co-ossified with the 

 maxilla on both sides. Temporal ridge marked, not interrupted at stephanion ; 

 heavily moulded posteriorly. Sagitta carinated. — Sconce 116 mm. — Skull rests on 

 opisthion ; it is of low grade if one can judge by the narrow high occiput. The 

 hyperbolic hard palate and the high alveolar processes are modern characters. 



1,838 ? , Mare Island, California. Aged 40 years, — subglobular. 



Glabella and supra-orbital ridges nil; outer half orbital margin scarcely inclined ; 

 forehead rounded. — Nasal bones mutilated, the frontal part marked, 4 mm., bridge 

 concave, moderately arched. — Nasal vestibule analophic. — Hard palate hyperbolic. 

 . — Alveolar process 10°. — Choanal much wider at base than apex. — Foramen spino- 

 sum imperfect on left side. Foramen lacerum medium open. — Petrosa moderately 

 inflated ; sphenoido-tympanic suture not overlapped by the spinous process.— Malar 

 bone with no marginal process ; bone enters into spheno-m axillary fissure ; suture- 

 trace present. — Skull rests on conceptacula. — Sconce 122 mm. 



Marked male, this rounded female skull resembles No. 1,783 of Moore series. 

 Rudimentary paramastoicls present. The occiput is rotund. 



1,836 <?, California. Presented by Wm. M. Gabb. Aged 25 years,— steno- 

 cephalic, platycephalic. 



Glabella and supra-orbital ridges prominent, 3 mm. ; outer part of orbital mar- 

 gin moderately inclined, 40°. — Nasal bones, mutilated, co-ossified. Length of outer 

 margin 29 mm. ; frontal 4 mm. — Nasal vestibule macrolophic ; incisor eminence 

 small ; incisor crest high ; nasal spine nil. Alveolar line discernible. — Hard palate 

 parabolic. — Alveolar process high. — Petroso-sphenoidal fissure overlapped by long 

 spinous process. Small exostoses in both auditory meatus. — Foramen lacerum 

 medium open, large. Scarcely any parietal mortise at post-squamosa. — Temporal crest 

 marked, greatly interrupted at stephanion. A small epipteric on left side. Skull 

 rests on conceptacula. — Sconce 82 mm., markedly porose. 



The skull closely resembles the foregoing, but is flatter. The width of sconce 

 is the narrowest in the series. The alveolar process is remarkably high. 



In these Indians the glabella was small, measuring between 2 mm. and 3 mm. 

 — The nasal bones were large, measuring 26 mm. ; the radix longest of the series 

 being 9 mm., and the salient, the shortest, 14 mm. ; the degree of the radix was the 

 lowest of any of the series, being 73° ; while that of the salient was the highest, being 

 45°. — The types of nasal vestibule were as follows : 5 macrolophic, 1 11 microlophic, 

 and 9 analophic, thus differing conspicuously from the Seminole and the natives of 

 the Santa Barbara Islands. — The average height of the alveolus was 16 mm. 

 — The hyperbolic variation was greatly in excess of the other forms of the hard 

 palate. There were 3 U-shaped palates, which is novel, and 5 parabolic. — The 

 1 The California skulls were on the border between line macrolophic andniicrolophic.
