2690. The seventeenth dorsal vertebra. 



The costal surfaces are smaller, and the metapophyses begin to receive the anterior articu- 

 lar surfaces from the zygapophyses. 



2691. A lumbar vertebra. 



The diapophyses are short and slender, with rudiments of anapophyses at their back part. 



2692. The three partially coalesced sacral vertebrae. 



In each of these the neurapophyses hare coalesced with the pleurapophyses and the 

 centrum. 



2693. The right scapula. 



A thick epiphysis covers the border at the base of the spine : the descending process from 

 the spine is well-developed. The acromion is short and pointed : the coracoid is a low, rough 

 tuberosity, confluent with the scapula. 



2694. The right humerus. 



The upper epiphysis is formed of two parts, one constituting the articular head, the other 

 the great tuberosity : the distal epiphysis is single. 



2695. The right ulna. 



The proximal epiphysis covers only the olecranon : the distal epiphysis forms the articular 

 surface for the radius and carpus. 



2696. The right radius. 



The proximal articulation is transversely elongate, partly convex and partly concave. An 

 epiphysis is present only at the distal end, where it is of large size. 



2697. The right scaphoides. 



The small surface for the radius is remote from that which supports the trapezium and tra- 

 pezoides.
