canals are not normal in form. The external base of the skull 

 presents several other interestmg features, one of which is the 

 form of the foramen magmim. 



An examination of the upper portion of the skull shows that the 

 sutures have begun to amalgamate. This is especially noticeable 

 in the coronal suture where it disappears after touching the tem- 

 poral ridge. On the left side, however, there is an excrescence 

 fonned by two spinous processes that arise a millimeter above the 

 plane of the alesphenoid. These excrescences are thin and cal- 

 careous and appear to be the result of an injury. 



The supraciliary ridges are heavy and their surface covered with 

 fine convolutions. The frontal bone slopes back and the forehead 

 is low. The occipital region is full but asymmetric, the left side 

 being larger. The nasal bone curves sharply out from the face 

 lifting rhinion above the plane of dacryon. This suggests a wide 

 and prominent probocis which must have appeared in life formid- 

 able as accentuated ■ by the beetling brows. The whole appearance 

 of the skull with its many ridges indicates an extraordinary mus- 

 culature. A list of the principal rectilinear measurements follows:
