284 Annals of the South African Museum. 



the present specimen the margin of the bone below the acromion 

 is exactly as in the unrestored type scapula. About 30 mm. below 

 the acromion the scapula is, of course, again greatly expanded to 

 meet the precoracoid. 



The coracoid is singularly short, and not more than about 10 mm. 

 is missing from the lower border of the right coracoid in the type 

 specimen. 



The precoracoid is also comparatively small. The anterior margin 

 is 22 mm. in front of the foramen, and the lower margin 26 mm. 

 below it. 



The clavicle is a short, rather stout bone, which stretches from the 

 acromion process down to middle line, probably meeting its neighbour 

 in front of the interclavicle. The upper end appears to have a broad 

 articulation with the acromion and the 20 mm. or so of the anterior 

 margin of the scapula below it. While the upper end is flattened to 

 fit the border of the scapula the lower end is flattened in the opposite 

 direction to fit the front of the interclavicle. 



The interclavicle is not very well preserved, and the posterior 

 portion is missing, but all the important features can be made 

 out. It differs from that of the Monotremes in being in no way 

 T-shaped. It is at least 130 mm. in length, and the broadest part 

 in front measures 63 mm. It is a little narrower in the middle, 

 measuring only 45 mm. wide, but posteriorly it widens out to 60 mm. 

 The lower half is somewhat concave in front.
