bone. This arrangement is unusual. The lambdoidal suture harmonic near aste- 

 rion with Wormian bone. Upper molars 4-4-0. — Sconce 140 mm. wide. — Skull 

 rests on conceptacula, yet is nearly platy basic. — Curves three in number : first, 

 opisthio-inion ; second, inio-lambdal ; third, lambdo-intertuberal. Skull markedly 

 "cut-off/" 



45(5 <?, aged 40, — spha?rocephalic. 



Glabella full, supra-orbitals, 2 mm. ; supra-orbital margin much inclined, 40°. — 

 Nasal bones convex, scarcely depressed; frontal portion nil; maxillary portion 21 

 mm.; premaxillary portion 6 mm.; radix 7 mm., 90°; salient 20 mm., 40°; 

 ascending process of maxilla nearly on plane of inner wall of orbit. Nasal vestibule 

 microlophic ; alveolar line trenchant, incisor crest and nasal spine moderately 

 developed ; alveolus 12 mm. — Hard palate hyperbolic ; alveolar height 12 mm. ; 

 choanal 15 mm., broadly oval. — Foramen lacerum medium open; spinous process 

 overlapping sphenoido-tympanic suture ; attempt at pterygo-spinosal union. — Tem- 

 poral ridge without interruption at stephanion ; lambdoidal suture serrate near 

 asterion. — Malar bone with small marginal, but marked suture-trace. — Sconce 

 128 mm. wide. — Skull rests on conceptacula. — An almost continuous curve from 

 intertubera to opisthion, a slight depression only occurring at the lambda and at the 

 occipital torus. 



708 <?, aged 30, — archencephalic. 



Glabella and supra-orbital ridge nil; outer part of orbital arch greatly inclined, 

 50°. — Nasal bones convex; frontal portion 2 mm.; maxillary portion 20 mm.; 

 ascending process of maxilla on plane with inner wall of orbit. — Nasal vestibule 

 microlophic ; incisor eminence small, ridge extending to bifid spine ; alveolar line 

 rudimentary, yet yielding a small fossa. — Alveolus small, 15 mm. — Hard palate 

 parabolic right, hyperbolic left. — Large overlapping spinous process ; projecting 

 tegmen on left. — Foramen lacerum medium small, but open both medianly and 

 laterally. — Petrosa inflated. — Temporal ridge interrupted at stephanion ; lambdoidal 

 suture serrate near asterion. — Ecto-petrosal portion of temporal bone serpiginous, 

 with several small Wormian bones. — Malar bone with marked marginal process ; 

 suture-trace present ; maxillo-zygomatic interval 5 mm. long. — Lachrymal bone large ; 

 hamulo-maxillary union. — Os planum large; bulla small. — Upper molars 4-3 2-3. — 

 Skull rests on conceptacula ; large transverse occipital torus. — The brain-case well- 

 filled; a continuous curve from bregma to opisthion. Width of sconce 130 mm.
