402 CRANIA FROM THE MOUNDS OF FLORIDA. 



A Wormian bone lies in asterion on both sides ; exostoses in both auditory 

 meati ; lambdoidal suture occupied by numerous coarse Wormians, like No. 1,789, 

 Moore series. Trace of metopic suture just above nasion. Slight exostosis on 

 either side of the occipital bone near foramen magnum. — Small paroccipital processes 

 present. 



In these twelve skulls from the Santa Barbara Islands eight were male and 

 four female. — The glabella and supra-orbital ridge are of moderate development, 

 the maximum being 4 mm., six being nil, and an average of six specimens being a 

 little over 3 mm. The degree of inclination of the supra-orbital margin is about 

 40°. — The average of the sizes of the nasal bone, measured from without, are frontal 

 portion 2 mm., maxillary part 16 mm., and the premaxillary part 4 mm. The 

 length of the radix is 6 mm., being smaller than in any other series, while the 

 salient is the same as in the Seminoles, but longer than in the western continental 

 tribes. — The nasal vestibule showed no example which was macrolophic ; five 

 were microlophic, and seven were analophic (some of the last named were transi- 

 tional forms to the second), thus demonstrating a lower form of the parts as com- 

 pared with the other groups. Three retained a small so-called prenasal fossa. — The 

 alveolus was 17 mm. high, being thus higher than in the Seminoles. — The shape of 

 the hard palate was noted in eleven examples, ten of these were hyperbolic and 

 one parabolic. The same proportions obtain in the Seminoles. — The shapes of the 

 choanae are also the same : four which are pantamorphic and seven which are 

 broader at the base than at the apex. — The foramen lacerum medium is remarkable 

 for being closed in two, nearly closed in six and distinctly open in three only. — 

 The spinous process of the sphenoid bone is also strikingly different from this pro- 

 cess in the other groups, since it overlaps the sphenoido-tympanic fissure in two 

 instances only. — All the malar bones possess a suture-trace on the posterior surface. 

 The bone enters into the spheno-maxillary fissure in five examples. The marginal 

 process is large in two specimens only. — The temporal ridge is interrupted at the 

 stephanion in two examples. The lambdoidal suture near the asterion is harmonic 

 in three instances. — The sconce had a minimum width of 104 mm., a maximum 

 width of 130 mm., and an average of 117 mm. — The lachrymal bone is small in 

 all (14 mm. x 8 mm.), and absent in two ; it joins the maxilla by the hamular 

 process in three instances only. — In no example of the lower jaw did the third 

 molar lie back of the anterior contour of the base of the coronoid process. The 

 mental foramen was never in advance of the second premolar, thus presenting a 

 contrast to the Seminoles. The condyloid process was faceted in all examples. 



Resume. — Dolichocephalic, male two, female one. — Mesaticephalic, male one, 

 female six. — Brachycephalic, male one. — Orthognathous, male two. — Mesognathous, 

 male five, female two. — Prognathous, male two, female one. — Leptorhine, male five, 1 

 female one. — Mesorhine, male two, female three. — Platyrhine, male two. — Meso- 

 seme, male two. — Megaseme, male seven, female two. — Microcephalic, male three, 

 female three. — Mesocephalic, male four, female one. — Megacephalic, male one. 



1 L. Carr (1. c.) from a larger number found the " nasal opening " of medium size.
