PEOFESSOE OWEN ON THE BEMAINS OF A LAEGE EXTINCT LAMA 
vol. vii. p. 172) ; it is described as follows : — “ This genus and species are established upon 
a fragment of the anterior extremity of an upper jaw of an animal of the Camel family, 
discovered by Mr. Henry Pratten, of New Harmony, Indiana, in the gravel drift of 
Kansas Territory. 
“ The specimen consists of portions of the left maxillary and intermaxillary bones, the 
latter of which contains the fang of a transformed incisor, or functional canine tooth as 
in the Lama. The intermaxillary bone is of very much more robust proportions than in 
the Lama or Camel. The inclination of its nasal border approaches more the horizon 
than in the Lama or Camel, apparently indicating the animal to have possessed a lower 
and perhaps a longer face than in either of the latter genera. The gingeval border is 
rugged as in its congeners, and it presents two irregular pits, apparently the alveoli of 
incisive germs. The fang of the functional canine contained in the intermaxillary bone 
is laterally compressed, conical, and is an inch and a half in length. From the orifice 
of its alveolus it is strongly curved upward and backward, nearly on a line parallel 
with the curved palatal margin of the bone. 
“ The crown of the tooth was directed downward and outward, and at the base it is 
ovate in section, with the narrow end posteriorly ; it measures six lines and three-fourths 
wide, and three lines and three-fourths transversely. A small portion of remaining 
enamel indicates this to have been thin and smooth. 
“ The small remaining fragment of the maxillary bone attached in the fossil exhibits 
at its broken margin the portion of an alveolus, situated an inch and three-fourths 
behind the tooth contained in the intermaxillary bone. It has been about four lines in 
transverse diameter, apparently had a direction curving downward, forward, and outward 
from its bottom, and probably accommodated a true canine tooth, although the position 
is usually far back, a necessary condition, however, in the Camelops from the distance 
to which the fang of the functional canine tooth extended backward”*. 
From the foregoing account of his materials much remains to be discovered in order 
to yield the generic and specific characters of Camelops Kansanus , Leidy. It is obvious 
that the description affords no grounds for identifying them with the Mexican fossils, 
the subjects of the present memoir. But it is of great interest to have such indications 
as Professor Leidy has recorded of the geographical extension of Cameloid forms into 
the Nebraska and Kansas territories of the great northern division of the American Con- 
tinent, and more especially after Don A. de Castillo’s discovery of Cameline remains 
in a locality of Central America. At the present day, as is well known, this restricted 
family of Ungulates is represented, in the New World, exclusively by the small Lamas, 
Pacos, and Vicugnas, wild or domesticated, in South America.
