THIS form was founded on a femur found at Amboulitsate in W. 

 Madagascar, and is described as follows : " It presents the same 

 general characters, and evidently belongs to an Aepyomis, but to 

 a different species, which we will call Aepyomis medius. The femur in 

 question is not only distinguished by its lesser proportions but by the 

 narrower external face of the bone; which variation results in causing the 

 whole area between the trochanter and the base of the femoral neck to be 

 much less depressed. The intermuscular line, which marks the insertion 

 surface of the deep portion of the femoral triceps muscle, is hardly indicated, 

 whereas it is very pronounced in the larger femur. The posterior side is 

 also more rounded, and the distance which separates the popliteal depression 

 from the proximal extremity is larger; the shape of this large depression 

 is, however, the same as in the larger femur, and although the articular 

 surfaces above it do show some differences, we know that these characters 

 are not very reliable as they are subject to individual variations. 

 Circumference of shaft 215 mm." 

 Habitat: West Madagascar.
