for the restoration whicli they published in 1890.' Subsequent 

 collections were made by Sternberg and Hatcher for the United 

 States Geological Survey, between 1884 and 1886. Later Professor 

 Cragin collected here, and in 1891 Mr. E. P. West of the Univer- 

 sity of Kansas, aided by Mr. T. R. Overton, began the extensive 

 collections which led to the preparation of the skeleton for the 

 University under the direction of Professor Williston.^ This skele- 

 ton, as mounted in the Kansas Museum and described by Williston, 

 gives a much more accurate idea of this animal than the pre- 

 vious restoration by Scott and Qsborn, in which the chest is 

 represented far too shallow. 



Its principal dimensions are as follows : Length, not including 

 tail, 9 ft. ; height, 4 ft. ; greatest girth, 9 ft., 4 in. 



The measurements of the American Museum skeleton as mounted 

 are : Length, 10 ft. 2 in. to bend of tail ; height at withers, 4 ft. 

 I in. ; greatest girth, 9 ft. 2 in. 



From the above accounts, and especially from our own observa- 

 tions, it is seen that this quarry represents an old bone-bed, probably 

 the deposit of some stream or small river along which the rhinoce- 

 roses herded in great numbers. The materials collected by the 

 American Museum party are extremely numerous, especially in 

 the skeletal parts, the figures running somewhat as follows : Skulls, 

 4 ; scapulae, 7 ; vertebrae, 159 ; humeri, 13 ; radii, 20 ; ulnae, 10 ; 

 carpals, 90 ; metacarpals, 38 ; pelves, 5 ; femora, 8 ; tibiae, 20 ; 

 astragali, 22 ; calcanea, 18. 



In this typical bone-bed are mingled individuals of both sexes 

 and of all sizes, and the proximity of one specimen to another is 

 not a certain guide. There are certain spots, however, where 

 considerable portions of individual skeletons have drifted to- 

 gether. We associate the skull and pelvis in our mounted speci- 

 men, for they are of similar age and were found within about six 

 feet of each other, the skull being that of a fully adult female, 

 and the pelvis indicating a corresponding age, because the ilia 

 are united above the sacrum ; with the pelvis moreover was found 

 a part of the jaw belonging to the skull ; also with this pelvis
