Type Specimen. — A right maxilla with the molars ; Geological Museum, Cairo. 
This species, which is known only from an imperfect right maxilla with the molars 
hi situ, is much smaller than S. antiquum, but in the structure of the molars it is 
apparently identical with the larger form. The length of the molar series is about 
20 mm. as compared with 34 mm. in S. antiquum. 
Form. & Log. — Fluvio-marine beds (Upper Eocene) ; north of Birket-el-Qurun.

A sj^ecies in some respects intermediate between S. antiquum and Megalohyrax 
minor, not only in size but also in some points in the structure of the teeth. 
The length of the molar and premolar series together is 7T cm., that of the molar 
series alone 3' 9 cm. 
Form. & Loc. — Fluvio-marine beds (Upper Eocene) ; north of Birket-el-Qurun. 
The last molar of this species differs from that of S. antiquum in having a less 
developed metastyle and consequently a less prominent posterior lobe. The other 
molars do not differ notably from those of the smaller species, except that the 
cingulum is rather more strongly developed. The premolars, which are greatly 
worn, do not seem to differ from those of S. antiquum except that qmi. 1 is more 
quadrate in outline. The canine succeeds the anterior premolar without any interval, 
and consists of a small anterior cusp (parastyle) and a triangular blade which, from 
the presence of a slight vertical fold in the outer wall of the tooth, may perhaps
