MOLAR TEETH AND OTHER REMAINS OE MAMMALIA. 
from tlie nasals by the maxillse, as in the living camel, or whether they reached up 
to them as in Auchenia. The discovery of an important dental character common 
to two such remote forms as C. simlensis and the American Auchenias is very inter- 
esting, and affords proof of the common origin of the two genera. 
Genus Dorcatherium, Kaup. 
The genus was originally described from the miocene strata of Eppelsheim by 
Professor Kaup ; the skull was furnished with long curved canines, and with bony 
peduncles for the antlers, in both of which characters it agrees with the living 
Muntjac of India, which may have been descended from the older form ; the cingu- 
lated molars of Dorcatherium are, however, quite peculiar. 
Erom the Siwaliks, specimens of the molar teeth were obtained by Ealconer, 
and in a manuscript note the specific name of D. moscMnum was assigned to these 
remains ; no figures or descriptions were, however, ever published, and so it is 
impossible to know to which of the forms noticed below the name was originally 
intended to apply. Eor this reason I have discarded the manuscript specific name 
and substituted new ones of my own. 
Specimens of the molar teeth of this genus have been obtained from Kushal- 
ghar, near Attock, from the Siwaliks of the Potwar district by Mr. Theobald, and 
from the Manchhar beds of Sind by Mr. Eedden. 
The teeth from these districts are at once seen to belong to two species, — a 
larger and a smaller ; besides this marked difference, other smaller varieties are 
noticeable in the specimens from the different localities ; these varieties are very 
probably of specific value, but for the present I have thought it better to describe 
all the specimens under two specific heads till more complete specimens shall render 
further specific distinction necessary. 
Dorcatherium majus, n. sp., nohls, var. a. — Kuslialghar near Attock, 
Plate 7, figs. 9, 10, 11. 
The two specimens from the above locality are those upon which Dr. Falconer, 
by some unaccountable oversight, founded the second species of Merycopotamus 
(M. nanus) {see “ Pal. Mem.,'' vol. I, p. 416). The larger of the two {figs. 9 
and 10) is the last upper molar of the right side ; it is untouched by wear, with the 
exception of the summit of the outer half of the anterior barrel ; the tooth is com- 
plete, with the exception of the posterior half of the cingulum, which has been 
broken away. 
The tooth has a nearly square base ; the whole of the inner half is surrounded 
by a deep and projecting cingulum, which forms a small tubercle at the entrance to 
the median valley ; the inner extremities of the barrels are blunt and rounded,
