Ti/j>e Specimen. — A right maxilla with the molars ; Geological Museum, Cairo. 



This species, which is known only ftom an imperfect right maxilla with the molars 

 in 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 xS". antiquum. 



Form. & Log. — Fluvio-marine beds (Upper Eocene) : north of Birket-el-Qurun.

Type Specimen:- — Eight maxilla containing all the cheek-teeth (PI. VI. fig. 3); 

 British Museum. 



A species 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 7"1 cm., that of the molar 

 series alone 3'9 cm. 



Form. & Log. — Fluvio-marine beds (Upper Eocene) ; north of Birket-el-Qurun. 



The last molar of this species difiers 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 pm. 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
