406 MEMOIRS OF THE CARNEGIE MUSEUM. 
1913. 
Osborn, H. F.—‘‘ Homoropus, An American Eocene Chalicothere.” Bulletin American 
Museum Natural History, Vol. XXXII, pp. 261-274. 
The author erects a new genus for the reception of Triplopus amarorum Cope, which 
he classifies as a Chalicotheroid. 
Prrrerson, O. A.—‘ A New Species of Moropus (M. holland) from the Base of the Middle 
Miocene of Western Nebraska.” Science, N. 8., Vol. XX XVIII, p. 673. 
NOTE. 
Since this memoir has passed through the press a careful reéxamination of the 
scapula doubtfully referred by us to the genus Moropus (see p. 230 and fig. 77 on 
p. 332) has led us to the conclusion that its identification with Moropus is in error. 
It may in passing be said that the dotted line in figure 77 has been started by 
the artist a little too high up on the supra-scapular border. 
While we hesitate to affirm that it is the scapula of a Titanothere, it neverthe- 
less more nearly resembles that element as found in the representatives of this 
family occurring in the lower Oligocene. The discovery of the remains of a Titano- 
there in the upper beds of the lower Miocene is, in view of what has hitherto been 
known as to their distribution, surprising, to say the least. 
CORRIGENDA. 
P. 205, 14th line from top for Phillotillon read Phyllotillon. 
Pp. 207 and 217. For pentelicum read pentelict. 
Plate LXVIII, fig. 1. Through an error of the draughtsman the sesamoid is repre- 
sented with its heavy end upward, the reverse of its true position, which is correctly 
shown on Plate LXIX, fig. 1.
