Type Specimen . — A left maxilla with pm. 2-m. 3 and the associated mandible with 
i. 2-m. 3, three cervical vertebrse, the distal half of a left humerus (text-fig. 38), and a 
right ulna ; British Museum. 
This species is distinguished from A. zitteli by its much greater size, its dimensions 
being nearly half as large again. The mandible attains a length of about 73 cm. ; 
the length of the three posterior upper premolars and the molars taken together 
is 34 ’5 cm. The lower premolars appear to have their crowns somewhat more 
compressed from within outwards than is the case in the type species, otherwise the 
dentition is closely similar in the two forms. The enormously massive humerus has 
its condyles rather more strongly developed than in the other s])ecies, and the 
flattening of the posterior face of the lemur seems to be even more strongly 
marked. 
Form. & Log. — FI uvio -marine beds (Upper Eocene) : north of Birket-el-Qurun.
