AESINOITHEETUM ZITTELI. 67 



C. 8252. Portion of right maxilla with the four milk-molars in situ. This specimen is slightly larger 

 than the last, but otherwise closely similar. 



C. 9436. Portion of right maxilla similar in age to the last, with mm. 2 and mm. 3 in situ. 



M. 8826. Portion of left maxilla somewhat younger than M. 8472, with mm. 4 and mm.. 3 in situ, 

 and the parts of the germ of the premolar replacing the latter. If this interpretation he 

 correct, the height of the crown of mm. 4 is very remarkable, the hypsodont condition 

 being quite as pronounced as in the permanent molars. Thus the width of the posterior 

 column of mm. 4, which is already somewhat worn, is about 3 cm., its height in a straight 

 line 7"7 cm. Presented by the Egyptian Government, 1904. 



M. 8474. Left premaxilla of young individual showing the germs of i. 1 and i. 2. 



Presented by W. E. de Winton, Esq., 1903. 



M. 8539. Plaster cast of the cranial cavity of the skull numbered M. 8463 (text-fig. 5). 



Made in the British Museum. 



M. 8540. Plaster casts of two cranial cavities of skulls in the Cairo Museum. 



Made in the Geological Museum, Cairo. 



M. 9087. Plaster cast of cranial cavity of an imperfect skull numbered C. 8794. 



Made in the British Museum. 



C. 8802. Nearly complete adult mandible in which the posterior column of m. 3 is considerably 

 worn. The anterior premolar, canine, and incisors are wanting, and the front of the 

 symphysial region is incomplete. The posterior end of symphysis is beneath anterior 

 column of m. 2. The ventral border of the horizontal ramus is strongly convex. Length 

 about 51 cm., height to top of coronoid process 32 cm., length of molar series 18 cm., 

 united length of last three premolars 8"1 cm. 



C. 8129. Nearly complete adult mandible. This specimen is mounted with the nearly complete 

 skull C. 8128, the posterior portion of the left ramus being restored. All the teeth in 

 front of pm. 2 are wanting. Length 55"5 cm., height to top of coronoid 36"5 cm. ; depth 

 of ramus beneath last molar 9*3 cm. ; length of molar series about 18 cm. ; length of last 

 three premolars about 10 cm. Figured in Frpntispiece. 



M. 8108. Left ramus of mandible, symphysial region much worn, and all teeth except m. 3 lost. 

 Length 55 cm., height to top of coronoid process 29'7 cm. 



M. 8462 b. Left ramus of mandible with symphysis : premolars and molars in situ. 



Presented by W. E. de Winton, Esq., 1903. 



M. 8821. Right ramus of mandible of a rather old individual, m. 3 being much worn. Anterior 

 end of symphysial region imperfect, and all teeth in front of pm. 2 wanting. Length 

 of ramus about 50 cm., height to top of coronoid 33 cm. ; depth of ramus beneath 

 m. 3, 9 cm. (approx.)j length of molar series 16"8 cm.; length of the three posterior 

 premolars 8"5 cm. Presented by the Egyptian Government, 1904. 



C. 8904. Imperfect ramus of mandible in which the last molar has just been cut. Teeth anterior 

 to pm. 3 wanting. The symphysis extended back to the level of the posterior lobe of 

 pm. 4. Length of m. 1 and m. 2 together about 10 cm.
