Recently Found Castoroides in Indiana. — Moore. 73 
No. 11. The third caudal vertebra in good state of preser- 
vation and indicating a much smaller specimen than No. 1. 
No. 12. Four inches of a right illium including the 
acetabulum nearly complete, and bearing two inches and more 
of the pubic arch. This shows the trihedral form of the illi- 
um and bears the rough, articulating surface by which it 
joined the sacrum. 
(Nos. 1 to 8 were all found either in the ditch or along the 
banks where the diggings were spread over the ground on 
either side, and all, with probably one exception, within a 
range of 30 rods along the banks. As a number of them were 
picked up by boys who worked the adjoining fields we cannot 
rely on the exact localities. I believe them to represent at 
least nine individuals, which may be suggestive of a colony.) 
No. 13. I have in trust a left lower incisor, 1H inches long- 
almost perfect. This belongs to Dr. J. W. Joy, of Richmond, 
Ind. It was found some years since near Greenville, Darke 
county, Ohio, in company with Mastodon remains. A de- 
scription of this tooth by Dr. F. W. Langdon, of Cincinnati, 
was published in the Journal of the Cincinnati Society of 
Natural History, Vol. 6, page 238. 
No. 11. A fragment of an upper incisor which I picked up in 
Wayne county, Ind., two miles east of Richmond, where a 
farmer was scooping out the wet earth for a fish pond. This 
was found along with sound teeth and decayed bones of the 
Mastodon. 
No. 15. A fragment of an upper incisor from near Sonora, 
Preble county, Ohio, said to have been found with remains of 
Mastodon. 
No. 16. Two to three inches of an upper incisor in the 
state cabinet at Indianapolis. Locality not given in the Indi- 
ana Report. 
No. 17. Remains found near Greenfield, Indiana, Hancock 
county. These belong to a Dr. Adams, who had sent them to 
a specialist for examination so that I failed to see them.
