372 CRANIA FROM THE MOUNDS OF FLORIDA. 



process 15 mm. ; no declivity. — Alai of vomer depressed below- level of basi- 

 sphenoid ; spinous process not overlapping petro-sphenoidal fissure ; foramen lacerum 

 medium open, both medianly and laterally ; petrosa inflated ; choanae small, 

 psedomorphic. The tympanic bone opposite spinous process, on the right is large 

 (6 mm.), but on the left side is almost nil. The tegmen tympani on the right large ; 

 left almost nil. The oval foramen on the right is large; on the left small and 

 nearly round. The jugular foramen on the right is small, on the left large. The 

 left ecto-petrosal portion of the temporal bone is intact; on left side a venous 

 foramen is seen in exoccipital at the lambdoidal suture ; the right ecto-petrosal 

 portion with large mastoid foramen ; upper part right and left ecto-petrosal .ser- 

 piginous.— Temporal impression feeble, no posterior moulding ; surface of temporal 

 fossa between tuber and ecto-petrosal flat, high, inclined ; skull resting on occiput. 

 Angle and parts of sagitta to intertuberal vertical. Occiput pa?clomorphic. Mus- 

 cular impressions faint, yet the supra-inial convexity marked. Upper half of 

 occipital squamosa and the interval between parietal tubera vertical. 



Lower Jaw. Condyloid process with facets, — the median abruptly declined ; 

 third molar in part concealed by the base of the coronoid process ; angle inclined 

 inward ; mental foramen right and left between the premolars ; coronoid line inter- 

 secting outer border of the condyloid process ; molar ridge to anterior border of 

 first molar ; mentum scarcely projecting ; genial spine and crest almost nil. 



The latitudinal index, less than altitudinal. This confirms Weisbach's opinion 1 

 that the female skull, in proportion to its length, is much narrower than the male. 



1,789 2 9 (Pis. LXVII, LXVIII, LXIX, LXX). Aged 45 years,— fragmen- 

 tary ; sutures open ; globular tending to subangular. 



Glabella and supra orbital ridges small ; outer part orbital arch much inclined, 

 50 mm. Metopic carination ; vascular groove on right side frontal bone. Alas 

 of vomer depressed from, plane of presphenoid. — Spinous process overlapping 

 petro-sphenoidal fissure ; petrosa inflated ; foramen lacerum medium very small on 

 right, closed on left.— Temporal ridge faint ; abrupt change in level of post-squa- 

 mosal and ectopetrosal parts ; bregma elevated. Malar bone enters spheno-maxillary 

 fissure ; marginal process small. Skull rests on posterior border foramen magnum. 

 Conceptacula well developed. Occiput broad, rotund ; inion marked ; no break 

 in occipito-parietal curve ; five large occipito-parietal Wormian bones ; depression 

 at obelion marked. General outline rhomboid with narrow anterior segment. 3 



Lower Jaw. Fragmentary without teeth in molar range ; genio-glossal spine 

 double ; genio-hyoid crest double ; all parts well defined. Inner side of ramus 

 beneath molar ridge occupied by an oblong convex eminence ; angle absorbed, body 

 much inclined ; condyloid articular surface not faceted, inner part inclined upward.

2 Burial mound Hitchen's Creek, Volusia Co., original burial from base. 



3 Skull well filled, no interruption in curves from highest point of sagitta to lowest jxtints of 

 conceptacula.
