Fio. 8. The inner surface of the left anterior ventrolateral plate of a 
third individual, a, b, c, and d, cross-sections of fig. 8, at right angles 
to the margin, at the points correspondingly lettered.

PRELIMINARY NOTICE OF A NEW SPECIES OF 
TEMNOCYON AND A NEW GENUS FROM THE 
JOHN DAY MIOCENE OF OREGON. 
By John Eyerman, F. Z. S., F. G. S. A., Easton, Pa. 
The collection made by the Princeton Scientific Expedi- 
tion of 1889 in the John Day ; 'bad lands" of Oregon contains, 
among many other interesting forms of Carnivora, an unusu- 
ally large form of Temnocyon, quite distinct from those de- 
scribed by Prof. Cope in his Tertiary Vertebrata. Almost 
the entire skeleton is preserved. I am under many obliga- 
tions to Dr. Scott for the free use of material from his mag- 
nificent collection, and still greater for very many valuable 
suggestions. 
Temnocyon, Cope. 
Talon of inferior sectorial trenchant; inferior molar 2 with 
trenchant crown and with no internal cusps. 
T. alligenis, the type of this genus, is described by Cope in 
his Tertiary Vertebrata (vol. in, book i, p. 903). 
TEMNOCYON FEROX. sp. now 
Larger than the type species; cranium unusually well de- 
veloped, being longer than in the tj r pe ; palate curved and of 
less diameter than that of T. altigenis; small antero-posterior 
development of the true molars. Superior premolars equal in 
antero-posterior diameter to and greater in transverse diam- 
eter than in the type. Unusual development of cingulum on 
superior molar 1, and the position of superior molar 2 with 
reference to molar 1. In the inferior dentition, the weak de- 
velopment of premolar 4 in hight, and in the antero-posterior 
diameter as compared with the transverse. The small size of 
the metaconid of molar 1, and the regular contour of its 
crown.
