M. 8868. Portion ot' rioht ramus of mandihlo with tlio molars and three posterior premolars. 
Fif);ured PI. VI. figs. 4, 4 a. The dimensions of the specimen (in centimetres) are: 
length of m. 3, Id) ; ni.2, I'l ; w. 1, ‘95 ; pm. 4, ‘1 ; pm. 5, ‘7 ; 'pm.2, ‘55. 
C. 8057. Portion of right ramus of mandihle with the premolars (pm. 2, and 3 incomplete), 
m. 1, m. 2, and part of m. 3. Length of ])remolar series 2‘G cm. Length of m. 2, 1'2 cm. ; 
m. 1, ‘9 cm. ; pm. 4, *8 cm. Depth of mandibular ramus beneath front of m. 3, 4 cm. 
C. 8106. PortioTi of a mandibnhir ramus of an old individual : m. 3 has a large crescentic talon 
and is much woim. The lengths (in centimetres) of the teeth are: m. 3, 1‘8 ; m. 2, P2 ; 
?/i. 1, 1'9 ; pm. 4, '8. 
Saghatherium majus, sp. nov. 
[Plate VI. fig. 5.] 
Type Sjiecimen. — Portion of right maxilla containing the canine, the first premolar, 
and the greater part of the second premolar; British Museum. 
An imperfectly known species provisionally referred to this genus, intermediate in 
size between Saghatherium magnum and Megalohyrax minor. Length of c. pm. 1, 2, 
4 cm. (in S. magnum, 2‘2 cm.); oi p>ai. 1, 2, 2’7 cm. (in M. minor, 3 cm.). Teeth 
considerably narrower than in M. minor, owing to the slight development of the inner 
cusp and of the postero-internal shelf. 
Form. & Loc. — Fluvio-marine beds (Upper Eocene): north of Birket-el-Qurun. 
M. 8434. Anterior portion of right maxilla with the canine, first preraolar, and the greater part of 
the second premolar. Type specimen. The canine is almost unworn ; it consists of a 
fairly high sharp main cusp, and a small anterior cusp, from which the cingulum, 
which is strongly developed, runs round the inner face of the tooth to its posterior 
angle. The outer half of pm. 1 is similar, but here there is a strongly developed 
antero-internal cusp and a postero-internal heel. Pm. 2 is incomplete, but it can be 
seen that it had a large antero-internal cusp and a postero-internal cusp on the 
cingulum. The lengths of the three teeth (in centimetres) are : c. 1'3 ; pm. 1, 1‘4 ; 
pm. 2, 1‘4. Total length of the three, 4 cm. 
C. 10010. Right upper m.2, probably of this species, figured on PI. VI. fig. 5. This molar is 
very like that of Megalohyrax minor, but is smaller and has the outer main cusps 
forming slightly greater projections on the ectoloph. The length of the ectoloph is 
1‘85 cm., in M. minor 2'6 cm., and in Saghatherium magnum 1'4 cm., so that there can 
be no doubt that this, like the other specimen, indicates the existence of another 
species intermediate in size between S. magnum and M. minor, and to this the name 
Saghatherium majus may also be applied. Length 1'9 cm., width 1'9 cm. 
M. 8453. Plaster cast of the above specimen. Made in the British Museum. 
M. 8879. Posterior portion of right ramus of mandible with the greatly worn m. 2 and m. 3 in situ. 
The length of m.2 is 1‘3 cm., that of m. 3, 1'7 cm. ; the depth of the ramus beneath 
m. 3 is 4 cm.
