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 E.), 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, 1 b, and 1 c.-^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, 197 in. Height of 

 occiput, 6"5 in. Breadth of occiput, 9-5 in. Length of molar series, 8'5 in. Length 

 of true molar series along alveolar border, 4 - ll in. Length of premolar series 

 along alveolar border, 4 - 4 in. Between anterior premolars, 2 - 4 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, 32 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 Sivutherium 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 XCL), 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 Eoyle's 'Illustrations of the Botany of the 

 Himalayan Mountains,' vol. ii., Plate VI. fig. 1 c. 



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), 162
