A MEDIAN HORNED RHINOCEROS FROM THE 
LOUP FORK BEDS OF NEBRASKA. 
By J. B. Hatcher, Princeton, N. J. 
Hitherto no median horned rhinoceroses have been reported 
from the western continent. During last April and May, 
while engaged in explorations for the Princeton Scientific 
Expedition of 1893, in the Loup Fork beds of Sheridan Co., 
Nebraska, the writer had the good fortune to secure, among 
other interesting vertebrate fossils from these beds, the re- 
mains of a rhinoceros with a well-marked, median, nasal horn. 
The material secured, while clearly belonging to the Rhinoe- 
eridae, represents, nevertheless, a new genus of that family, 
which may be called Teljeoceras in reference to the position of 
the horn on the end of the nasals. The species may be called 
major, in reference to its size, which is decidedly greater than 
that of any other known American member of the Rhinocer- 
Ldse. 
The type specimen of TeleoQeras major consists of the 
greater portion of the skull and lower jaw. These represent 
an animal about one-third larger than Aphelops fossinger 
(Cope). The teeth are very much worn, showing the individ- 
ual to have been fully adult. It is readily distinguished from 
all known genera of the Rhin&ceridct by the following combi- 
nation of characters: Absence of a crochet and presence <>f 
an anticrochet on the superior molars and premolars ; with tin- 
presence of a sagittal crest ( V) and of a median horn situated 
on the extreme point of tin- nasals. This horn is directed for- 
ward and upward, and extends considerably beyond the ex- 
tremities of the nasals proper.
