288. The vertebral portion of apparently the fourth rib of the left side. 



289. The vertebral portion of apparently the fifth rib of the left side. 



290. The vertebral portion of apparently the sixth rib of the left side. 



291. The vertebral portion of apparently the seventh rib of the left side. 



292. The vertebral extremity, including the neck and tubercle of apparently 



the seventh rib of the right side. 



293. The head and neck of apparently the eighth rib of the left side. 



294. A fragment of apparently the corresponding rib of the right side. 



295. The vertebral portion of apparently the ninth rib of the right side. 



296. The vertebral portion of the corresponding rib of the left side. 

 297- The vertebral portion of apparently the tenth rib of the right side. 



298. The head, the tubercle, and the shaft, in three separate pieces, of the cor- 



responding rib of the left side. 



299. The vertebral portion of the eleventh rib of the right side. 



300. The portion of the corresponding vertebral rib of the left side. 



301. The vertebral portion of the twelfth rib of the right side. In this the 

 articular surface has disappeared from the tubercle, but the two articular 

 surfaces of the head and neck remain distinct.
