10 PROFESSOR ALLMAN ON THE CHARACTERS 



The SkulL-Yieyyedm 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 

 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 bulls. 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. 

 The anterior condyloid foramina are very large. 



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 bullse 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
