224 MEMOIRS OF THE CARNEGIE MUSEUM. 
The species, remains of which have been recovered in most perfect condition 
in the Agate Spring Quarry, has been identified both by the writer and his colleague, 
Mr. Peterson, as Moropus elatus Marsh. The types preserved in the collection of 
Professor Marsh in the Yale Museum are fragmentary, but they absolutely agree 
in every respect with the corresponding portions of the animal remains of which 
were found in Carnegie Hill. If type specimens have any value whatever in 
enabling the determination of a species, then it is true that the remains above 
alluded to, which were recovered during the seasons of 1904 to 1908, belonged to 
the animal named Moropus elatus by Marsh.

In October, 1908, the writer received from Professor Erwin H. Barbour a 
copy of an account of the fragmentary cranium of Moropus which he recovered in
