Anderson, The Notes on the Temporal bone in Mammalia etc. gi i 



Mastoid flat. Petrous (with tympanic) slightly convex. In this 

 form and Anubis the parietal is separated from the sphenoid by 

 an extension of the temporal to frontal. 



Papio. The large smooth surface between temporal crests 

 is wide in front and narrow behind, 4.2 cms in front, 2 cms be- 

 hind. Ant. post. temp. 6 cms. frontal part 1 cm. There is a tem- 

 poro-frontal suture here. Vertical diameter of squamous 2.5 cms. 

 Parietal to ridge 3 cms. The zygoma is arched. The temporal 

 fossa is somewhat convex. Distance of zygoma above jaw 2 cms. 

 The groove between post glenoid spine and tympanic deep. Tym- 

 panic is ridged externally. Petrous projects downwards. Mastoid 

 flat and in same surface level as outer ridge of tympanic. 



Ateles sp. The Space between temporal ridges is much wider 

 behind than in front. 4 : 5.5. There is a prominent post glenoid 

 spine. Ant. post. sq. 4.5 cms. fronto-par. 0.8 cms. Vertical height 

 sq. 1 cm. Temporal par. suture to temp. ridge 3.5 cms. Mastoid 

 somewhat convex and with occipital forms an ellipsoidal curve 

 from side to side. Occipito-malar suture is 2 cms long. The 

 petrous is flattish internally and convex externally on the lower 

 surface. Mandibular lower border to Coronoid 4.5 cms. Coronoid 

 to temporal ridge 4 cms. 



Mycetes sp. The posterior glenoid spine is broad (and long). 

 Vertical height of squamosal is 1 cm. Temporo-parietal suture 

 to crest 3.5 cms. Ant. posterior sq. 4 cms. Fronto-malar part 

 1.5 cms, breadth of surface between temporal ridges 3 cms widest. 

 Lower border of mandible to coronoid 7 cms. Coronoid to tem- 

 poral ridge 3.8 cms. Posterior glenoid spine well-marked. Mastoid 

 par. occ. process with a small flattish surface behind meatus. 



Mycetes siniculus. Ant. post. Temp. (?) vertical height 

 1.5 cms. Temp. P. Mal suture to crest 3 cms. Space between 

 temporal fossa wide in front, and gradually narrows to 0.7 cms, 

 and then widens again. Ant. Post. Frontal malar part 2 cms. 

 Lower border of mandible to coronoid 8 cms. Coronoid to crest 

 4 cms. Mastoid convex and uneven, Slight-process below. Pe- 

 trous, convex and prominent below, The base of skull is concave 

 between petrosals. 



Mycetes sp. Ant. Post. sq. 5 cms. Vertical 1.5. Temp. parts 

 crest 3.7. Crest to sagittal suture 1.2 cms. Sagittal to coronoid 

 5.8 cms. Coronoid to lower border of mandible 6.6 cms. Tym- 

 panic flat. Petrous lower surface somewhat convex. Mastoid 

 forms a process below in conjunction with the occipital. The 

 parietal forms the greater part of temporal fossa. The posterior 

 root of the zygoma is almost as high as the Tempero-parietal 

 suture. This may be regardet as an expression 

 of the importance of the mandibular and 

 maxillary pressures in deviating the n u - 

 trient material.
