Norma faciali-f. — (PI. ix., fig. 1). The edge of the maxil- 

 lary border of tiie nares, from the level of the lower margins 

 of the nasal boufs half-wav to the level of the inferior tubinal, 

 is grooved. The floor of the nose seems to be continuous with 

 the incisive region by a smooth area ; but closer examination 

 shows that this area is crossed by a fine, thin, sharp, low 

 ridge which runs on each side from the outer margin to the 

 nasal spine, joining the parasternal line before reaching the 

 spine. The nasal spine is distinct, though not large. The 

 anterior nares are fairly wide, the nasal index being 52. The 

 skull is therefore raesorhine. bordering on platyrhiue. The 

 gnathic index, measured by Flower's method, is 104-.3. 

 The infra-orbital fossge are fairly deep and are marked off 

 from the canine fossae by slight ridges. The incisive fossae are 

 shallow. The fronto-malar border of the orbit is somewhat 

 thickened. The suture forming the continuation forwards of 

 the infra-orbital canal is patent, and turns inwards behind 

 the margin of the orbit. On the outer wall of the orbit, on 

 both sides, the suture between the sphenoid and the malar 

 runs downwards, courses for a little way along the anterior 

 border of the spheno-maxillary fissure, and passes forwards 

 and inwards on the floor of the orbit to become continuous 

 with the maxillo-malar suture. A sutura verticalis is not 

 present on either side, but on the left side a short suture runs 

 nearly vertically from tlie orbital margin to an accessory 

 infra-orbital foramen, whence a crack passes downwards and 

 inwards to the borders of the " nasal wall." On the right side 

 there are two accessory infra-orbital foramina, the lowest or 

 normal foramen being separated from the middle one by a 

 distinct ridge. The vertical diameter of the os planum is 

 11 mm. The orbital index is 85, which makes the skull 

 mesoceme. The inter-orbital width is 22 mm. 



NoDiia huftihiris. — (PI. x., tig. 2). The hard palate index is 123. 

 There are traces of the maxillo-premaxillary sutures. The 

 margins of the anterior palatine fossa are injured ; but the 

 fossa appears moderate in size, and is shaped like an isosceles 

 triangle. On the right side of the palate, just in front of the 

 palato-maxillary suture, there is a bridge of bone bounding a 

 foramen. On the left side there are two accessory palatine 

 foramina on the palate bone, a larger antero-external and a 

 smaller postero-internal, separated by a well-marked ridge.
