mm ; choanse paedomorphic. — Sphenoido-tympanic suture scarcely overlapped. — Fora- 

 men lacerum medium scarcely open. — Temporal crest weak, parieto-sphenoidal 

 suture obliterated. — Skull rests on conceptacula. — Sconce 104 mm. — Malar without 

 marginal process ; not in spheno-maxillary fissures ; suture-trace present. — Lachry- 

 mal bone rudimental. — Middle turbinals laminate. — Rudimental paroccipital 

 processes. , 



1,816 ?, aged 25 years, — eurycephalic. 



Glabella and supra-orbital ridge faint. Nasal bones broad depressed, mutilated ; 

 frontal portion nil. — Nasal vestibule analophic ; alveolus high, 22 mm. — Hard palate 

 hyperbolic; alveolar process 15 mm.; choanse with base wider than apex. — Sphe- 

 noido-tympanic suture not overlapped by the spinous process. Foramen lacerum 

 medium closed laterally. — Temporal ridge not interrupted at stephanion ; lamb- 

 doidal suture harmonic near asterion. Skull rests on conceptacula. 



Lower Jaw. Condyloid process much angulated, lateral facet much worn. 

 Coronoid process not concealing third molar ; mental foramen on line of the second 

 premolar ; genial spine single prominent ; genial crest almost nil, set in a fossa. 

 Upper molars 4-3-0 ; lower molars \ 1°. 



1.820 2 , aged 35 years, — cymbecephalic. 



Glabella and supra-orbital ridge faint ; superior orbital border slightly inclined, 

 40°. — Nasal bone 26 mm. long; frontal portion 2 mm. ; maxillary portion 20 mm.; 

 premaxillary portion 2 mm.; radix 7 mm., 80°; salient 16 mm., 50°, low arch, 

 asymmetrical. Nasal vestibule analophic; alveolus 18 mm. — Hard palate hyper- 

 bolic ; alveolar process 12 mm. — Sphenoido-tympanic suture not overlapped. — Petrosa 

 moderately inflated. — Foramen lacerum medium scarcely defined. — Lachrymal bones 

 rudimental. Hamular process not touching the maxilla. — Malar bone with small 

 marginal process ; bone enters spheno-maxillary fissure ; suture-trace present. — 

 Parieto-sphenoid junction small, 10°. — Small mortise. — Sconce 118 mm. — Skull rests 

 on opisthion. Phasnozygomous. The nasal bone creeps in a little between the 

 ascending process of the maxilla and the frontal bone. This is a character of Cer- 

 copitheais. Right side of occiput with large exostosis. Small transverse occipital 

 torus present. 



1.821 <?, aged 40 years, — archencephalic. 



Glabella and supra-orbital ridge moderate, 3 mm. ; superior orbital margin 

 much inclined, 50°. — Nasal bone high arched. Frontal portion 2 mm. long; max- 

 illary portion 16 mm.; radix 3 mm., 90°; salient mutilated. Nasal vestibule 

 microlophic, with ridge extending forward from incisor eminence. — Hard palate 

 hyperbolic; alveolar process, 17 mm. — Foramen lacerum medium almost "closed ; 

 petroso-sphenoidal fissure greatly overlapped. Malar small, 12 mm. wide with 

 large tuberosity ; marginal process enormous. The bone does not enter into the 

 spheno-maxillary fissure ; suture-trace present ; external surface at beginning of 

 bipartite suture evident. Skull rests on opisthion.
