118 FAUNA ANTIQUA SIVALENSIS. 
[Plate XCII. completes the series of published plates. Copies 
of the seventeen plates which follow, and which I have de- 
signated by letters (A. to R.), were found among Dr. Falconer’s 
papers, or have been furnished by Mr. Ford, the artist and litho- 
graphic engraver. These plates had been executed on stone, 
and proof impressions struck off, but the plates were never 
published, and unfortunately the stones were destroyed during 
Dr. Falconer’s absence in India. These seventeen plates have 
been deposited in the library of the Geological Department 
in the British Museum, and from them several of the specimens 
in the Museum have been named. Through the kindness of 
Mr. Davies, I am enabled to give the British Museum Catalogue 
number for each of the specimens figured, so that there will 
be no difficulty in referring to the originals. | 
PLATE A. 
Figs. 1, la, 1b, and 1le.—Sivatherium giganteum. Cranium of 
female, with perfect series of six molars on either side. ‘The specimen 
is broken off in front of the molar ridges.—B.M. No. 39,523. 
From anterior margin of foramen magnum to alveolus of first molar, 16: in. 
From anterior to posterior side of last molar, 8°25 in. Width of skull between 
borders of auditory foramina, 9°3 in. From the anterior margin of auditory foramen 
to the rear molar, 69 in. Extreme length of fragment, 19°7 in. Height of 
occiput, 6°5 in. Breadth of occiput, 9°5 in. Length of molar series, 8°5 in. Length 
of true molat series along alveolar border, 4:11 in. Length of premolar series 
along alveolar border, 4°4 in. Between anterior premolars, 24 in. Between 
posterior molars, 4:3 in. Length of palate in mesial line from anterior edge of 
first premolar to palatine notch, 6°10 in. Length from lower border of foramen 
magnum to palatine notch, 9°5 in. Probable width across external orbital angles, 
12°in. Length of orbit, 3-2 in. Length between auditory process and posterior 
border of orbit, 6°5 in. Probable height at posterior border of palate in mesial - 
line, 6°5 in. 
Figs. 2 and 2 a.—Portion of cranium of Sivatherium giganteum, found 
by Col. Colvin in the lower hills below and west of Nahun. The 
specimen is valuable, though it has no teeth, from having the occiput 
very entire, and from its proving the accuracy of Dr. Falconer’s 
assumptions, made before the specimen was found, and based on exami- 
nation of the original head (Plate XCI.), that the animal had four 
horns with bony cores, as this has the offset of one of the back branched 
horns very clearly marked, and suitable to which a large flat horn was 
found in Capt. Cautley’s collection, fig. 4. The parts appear slightly 
distorted from the occurrence of a shift. This specimen is figured and 
described by Col. Colvin in the Jour. As. Soc., Feb. 1837, vol. vi. 
p- 152. It is also figured in Royle’s ‘ Illustrations of the Botany of the 
Himalayah Mountains,’ vol. ii., Plate VI. fig. le. 
This specimen was presented by Col. Colvin to the Museum of the 
University of Edinburgh, where it now is. Its dimensions are as 
follows :— 
Length from occipital crest to anterior margin of base of anterior horn-core (on 
right side), 14:2 in. Between extreme points of occipital crest (imperfect), 16°2
