Portion of riglit maxilla with the four milk-molars in situ. This specimen is slightly larger 
than the last, hnt otherwise closely similar. 
Portion of right maxilla similar in age to the last, whth min. 2 and mm. 3 in situ. 
Portion of left maxilla somewhat younger than M. 8472, with ?n?n. 4 and mm..‘?> 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 hy the Egyptian Government , 1904. 
Left premaxilla of young individual showing the germs of i. 1 and i. 2. 
Presented hy W. E. de ^]dnton, Es<p, 1903.

Nearly complete adult mandible in which the posterior column of m. 3 is considerably 
wmrn. 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 })remolars 8T cm. 
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 coi’onoid 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 Frontispiece. 
Left ramus of mandible, symphysial region mitch worn, and all teeth except m. 3 lost. 
Length 55 cm., height to top of coronoid process 29'7 cm.

Presented hy TF. 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.); length of molar series 16‘8 cm.; length of the three posterior 
premolars 8'5 cm. Presented hy 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
