molar, figs. 4, 4 A. With these there were also associated the distal epiphysis of a left 

 ulna, the distal half of a right radius, a left scaphoid, a left unciform, a left fourth 

 metacarpal, and a right magnum. Presented hy W. E. de Winton, Esq., 1903. 



M. 8475. Upper portion of skull of very young animal showing parieto- frontal suture and anterior 

 border of the frontals. This specimen also shows that the great frontal sinus is 

 continued into the frontal (posterior) horn. There is no trace of the occipito-parietal 

 or inter-parietal sutures. Presented hy W. E. de Winton, Esq., 1903. 



M. 8463 a. Right maxilla with the molars and last two premolars preserved : w. 3 is well worn, the 

 animal being old. The base of the zygomatic process is preserved ; the antorbital 

 foramen is smaller than in most specimens. The length of the molars is 18"2 cm., that 

 of the two premolars 7*5 cm. This maxilla may belong to the same individual as the 

 mandible M. 8462 h. Presented hy W. E. de Winton, Esq., 1903. 



C. 7843. Palate and cheek-teeth of a young individual in which pm. 4 is just being cut and pm. 3 

 is slightly worn ; m. 3 and one of the anterior incisors of the right side are just 

 appearing. The base of the zygomatic process and the antorbital foramen are 

 preserved. 



C. 7918. Left maxilla of a young individual in which pm. 4 and the hinder column of m. 2 are 

 slightly worn. The length of m. 1 and m. 2 together is 10'2 cm. ; length of 

 pm. 2-pm. 4, 8"4 cm. 



C. 7844. Right maxilla with pm. 2-pm. 4 and m. l~m. 3. Last molar just cut, but not in wear. 

 Length of «i. 1-m. 2 is 10"2 cm. ; length of pm. 2-pm. 4 is 8'4 cm. 



C. 8253. Left maxilla rather older than the last, m. 2 being more worn. The posterior column of 

 m. 3 is missing. The length of m. 1-m. 2 is 11"6 cm. ; length of pm. 2-pm. 4 is 8"6 cm. 



M. 8801. Portion of left maxilla with the molars and pm. 4 in situ. The posterior column of m. 3 



not yet in wear. Length of molar series about 15"5 cm. 



Presented hy the Egyptian Government, 1904. 

 M. 8803. Portion of right maxilla with m. 2 and m. 3, the posterior lobe of the latter just coming 



into wear. Presented hy the Egyptian Government, 1904. 



M. 8472. Portion of left maxilla and anterior end of jugal ; the antorbital foramen is preserved. 

 One tooth, probably the last milk-molar, is in situ ; above and a little in front of this is 

 the fossa, in which lay the germ of pm. 4 or pm. 3. The milk-molar is entirely 

 molariform ; the length of the inner side of the crown is 4'2 cm. 



Presented hy W. E. de Winton, E.fq., 1903. 



M. 8471. Portion of left maxilla with three teeth in situ, probably mm. 2, mm. 3, and mm. 4 : 

 mm. 1 and a milk-incisor are also preserved. Mm. 4 is much less worn than in 

 the last specimen ; both it and mm. 3 are molariform. Mm. 2 consists of an outer wall, 

 two transverse crests, and a well- developed cingulum on the antero-internal border ; 

 mm. 1 consists of an outer wall composed of two elements and united anteriorly by a 

 slight transverse crest with the strongly developed cingulum. The incisor is a small^ 

 cylindrical, slightly spatulate tooth without a cingulum. The lengths of the milk-molars 

 are : — mm. 1, 1'9 cm.; mm. 2, 2-3 cm. ; mm. 3, 3-3 cm.; mm. 4, 4-1 cm. Figured on 

 PI. Y. figs. .5, 5 a, and text-fig. 7. Presented hy W. E. de Winton, Esq., 1903.
