CRANIA FROM THE MOUNDS OF FLORIDA. 371 



between premolars, on right side between second premolar and first molar ; genio- 

 glossal spine double ; genio-hyoid crest scarcely seen. — Teeth much worn, cuspi- 

 dation lost ; upper incisors vertical ; third molar absent ; the first molar with 

 lateral roots projecting from the sockets. 



l^Sl 1 S (Pis. LVIII, LIX, LX, LXI, LXII). Aged 35 years,— sutures open ; 

 subglobular, pi a ty cephalic. 



Glabella and supra-orbital ridge small, 2 mm. ; outer part of orbital arches 

 scarcely inclined downward, 25 mm. ; forehead ample yet frontal eminences approxi- 

 mate ; interfrontal suture persistent ; symmetrical vascular grooves near temporal 

 ridge. — Nasal bones low arched, synostosed ; markedly concave from above down- 

 ward ; radix 30° ; salient 20° ; ascending process maxilla nearly at right angles to 

 inner wall of orbit. Nasal vestibule microlophic with incisor, eminence small, 

 alveolar line indistinct ; crest high ; inter-premaxillary suture of alveolus carinate ; 

 alveolus high ; inferior turbinal crest near floor. — Hard palate U-shaped, hyberbolic, 

 no declivity in front, high alveolus. — Vomer depressed below plane of basisphenoid ; 

 choanae with base wider than apex ; spinous process overlapping petro-sphenoidal 

 fissure ; petrosa inflated ; middle meatus concave at palatal bone ; pterygoid pro- 

 cess narrow. — Malar bone with scarcely any marginal process on right side, but 

 quite large on left ; suture-trace present ; tuberosity marked ; the bone enters into 

 the formation of the spheno-maxillary fissure. — Temporal crest faint, interrupted at 

 stephanion 22 mm. ; at occipitoparietal union temporal crest is heavily moulded ; 

 suture near asterion almost harmonic ; abrupt break between post-squamosa and ecto- 

 petrosal right, but none on left ; at upper parieto-temporal union, the linea semi-circu- 

 laris, is not visible on the right, but the upper part defined on the left, and occupied 

 on both sides by vessel-grooves. — Lachrymal bone small ; bulla? ethmoidales large. — 

 Arcs of longitudinal curve as follows : inio-opisthonic ; inio-intertuberal ; intertubero- 

 nasion. The supra-occipital projects slightly beyond lambda. — Sconce rugose in 

 inio-intertuberal part, 114 mm. wide. — Occiput broad rounded. 



Lower Jaw. Line of coronoid intersects condyloid at outer third ; the external 

 facet of condyloid process one-third of the articular surface, — the downward inclined 

 internal facet two-thirds not angulated ; the left external pterygoid impression the 

 least defined. Third molar well in advance of base of coronoid process ; the 

 masseteric and internal pterygoid impressions about equal, the angle not deflected ; 

 mental foramen symmetrical between the second premolar and first molar ; molar 

 ridge scarcely reaching first molar ; tubercle in advance of pregonial fossa ; genio- 

 glossus spine single ; genio-hyoid crest nil. 



1,783 2 i (Pis. LXIII, LXIV, LXV, LXVI). Aged 25 years,— globular, 

 fragmentary; sutures open. 



Glabella none ; supra-orbital ridge none. — Hard palate U-shaped ; high alveolar
