PAUNA OP THE INDIAN PLHVIATILE DEPOSITS. 
At least three species of Rhinoceros appear to have been found fossil in 
Burmah, but have not yet been named and determined : of these one was de- 
scribed and figured by Mr. Clift in the Transactions of the Geological Society, 2nd 
Series, Vol. II, “ but not named:” the other two are represented by specimens in the 
Geological Museum, Calcutta. Mh. Deccanensis differs specifically from all three. 
Of the animal described by Mr. Clift, two much worn left upper molars are there 
shown, in both of which the posterior valleys form deep notches in the posterior 
wall — a character not seen in Deccanensis. The crochets also are mere waves in 
the enamel walls of the median collis. The anterior outer angle of the teeth is less 
acute and less projecting than in Deccanensis. K 2 , the second costa on the outer 
wall, is also less prominent than in my new species. 
The second Burmese species is represented by a very large and fine left upper 
molar,* which must have belonged to a very large animal, and far exceeds the 
largest tooth of Bh. Deccanensis in size. It is less tall crowned ; has the guard 
well developed anteriorly, but faintly only on the inner side. A fan-shaped 
denticule stands at the mouth of the pass into the relatively much shallower 
anterior valley, and a furrow in the enamel wall descends from the anterior coUis 
into the valley just within the pass — a feature not met with in Bh. Deccanensis. 
There is only one simple crochet. The posterior area of the outer wall is deeply 
concave instead of being flat, and the posterior outer angle is much less acute than 
in the Deccan species. 
Two right upper premolars, also in the Geological Museum, Calcutta, derived 
from an animal considerably smaller than Wi. Deccanensis^ represent the third 
Burmese species. They are characterized by the excessive development of the second 
costa of the outer wall ( A; 2 ) in a very median position, and relatively much poste- 
rior to the position of the moderate-sized second costa in Bh. Deccanensis. Two 
straight spur-like crochets project into the very deep anterior valleys. The more 
forward of the two crochets, which corresponds to h\ in my species (see Plate I, 
figs. 1 and 2), is the larger, and juts out nearly at right angles to the outer wall 
of the tooth. The anterior and median colies are narrower and more obliquely 
placed than those in Bh. Deccanensis. It is only on the anterior side of the front 
tooth that any guard is shown. 
At the same time that I obtained the remains of Bh. Deccanensis, I found, 
lying loose in the bed of the nullah, a fragment of 
Associated remains. . , , i i i , 
a right maxilla with two teeth (probably molars 2 
and 3) of a large bovine animal, allied to Bihos gaurus, which still lives in the 
Syhadri range. f The condition of the specimen and character of the encrustation 
covering it indicated that it came from a position corresponding to that of the 
Rhinoceros now described. In the following season, 1872, I had an opportunity

Commissioner of Burmah.
