10 PROFESSOR ALLMAN ON THE CHARACTERS 
The Skull.—Viewed in its vertical aspect, the skull presents a piriform shape between 
the occiput and a line immediately behind the orbits, and then, becoming suddenly con- 
tracted, it is bounded by parallel sides as far as the end of the muzzle, interrupted, 
however, by the projection of the posterior part of the alveolar Fig. 6. 
border of the maxillaries. The profile contour of the skull, from the 
lambdoidal crest to the nostril, is nearly a straight line. 
The basioccipital is thin and flat, broader than long, and extends 
forwards as far as the junction of the posterior and middle thirds of 
the tympanic bulle. The occipital condyles are large, about a line 
distant from one another below; and thence extending upwards and 
outwards, they reach a point a little above the level of the superior 
margin of the foramen magnum. ‘The foramen magnum is trans- 
versely oval; its plane extends upwards and backwards at an angle of 
about 100° with the base of the skull. The supraoccipital extends 
upwards and forwards, and forms by its upper and outer edge a well- 
marked, sharp, lambdoidal ridge. The paramastoids constitute two ‘ 
small but well-marked processes, which extend horizontally backwards. Skull, vertical as-

The basispenoid is broad behind at its junction with the basioccipital, and then 
rapidly contracts as it passes forwards, forming on the cerebral aspect a narrow vertical 
crest between the internal openings of the foramina lacera anteriora: there are no 
clinoid processes,

The tympanic and petrosal bones unite to form tympano-petrosal bull of moderate 
size. 
The sagittal suture is obliterated, its place being taken by a nearly obsolete sagittal 
crest. 
The coronal suture is very faintly indicated by a line which forms an arch, very con- 
cave in front, where it embraces the posterior margin of the frontal bones. These are
