suggestion of a small one on either side. It is probable that minute costal elements have 

 been lost. The change of the articular processes is above the lOtli, the spinous process of 

 which is transitional. The transverse processes of the 20th vertebra are injured; but it 

 seems that the spread in the lumbar regions is not normal. Those of the 4th lumbar 

 (23d) are much like those of a last one ; but there is no penvdtimate. The 24th is the 

 1st sacral and the fiilcralls, with a distinct promontor}' above it, but its arch is more like 

 a linnbar one than that of the 1st sacral should be. There is no secondary promontory. 

 The auricular surfaces extend onto the 3d sacral. There is no conjucjata vera. The sac- 

 rum has six vertebrae, but the last is evidently the l.st coccygeal. The 2d coccygeal is 

 attached to the 1st, but the union is, probably, not bony. The 3d and 4th are fused 

 together and separate from those above. 



In the absence of measurements of the fresh spine the height of the bodies has been 

 taken. It is clear that the proportions are rather more accurate if the 19tli be counted as 

 a thoracic and not as a lumbar. As far as its morphology goes, it could be put in either 

 region.
