additional Fragments of the Sivatherium. 41 



land. This fragment is the more valuable on account of its 

 being perfect in the parts deficient in Dr. Falconer's speci- 

 men, published in the Asiatic Researches, vol. xix.* We 

 subjoin the Colonel's note, explanatory of the drawings [Plate 



" I herewith send you figures of the Sivatherium; one of 

 the portion of the head I was fortunate in having brought 

 in from the lower hills below and west of Nahan, just before 

 I left Dadiipur. It arrived iencumbered with a good deal of 

 hard sandstone matrix, most of which I had cleared away. 

 This specimen is valuable, though it has no teeth, from ha- 

 ving the occiput very entire, and from its proving the accuracy 

 of Dr. Falconer's assumption, founded on examination of the 

 original head, that the animal had four horns with bony cores, 

 as this has the offset of one of the back branched horns very 

 clearly marked ; suitable to which I may mention, that Capt. 

 Cautley has found in his collection a large flat horn. In this 

 plate, fig. 1 ; is a view of the occiput appearing, partly distorted 

 from occurrence of a shift. For the left lower jaw of the Si- 

 vatherium, delineated in the same plate, I am indebted to Con- 

 ductor W. Dawe, of the Canal Department, for whom it was 

 brought in, inclosed in a mass of similar sandstone, from near 

 the sources of the Sombe river, north of Dadupur, and east of 

 Nahan, shortly before I came away. It is a very perfect and 

 beautiful specimen, with its molars, four in number, almost 

 quite entire, and is the specimen which you have moulded. 



" Fig. 2 is of the outside of the left lower jaw. 



" Fig. 3, ditto crown of the teeth, in which I have endea- 

 voured to be accurate in drawing the flexures of the enamel. 



" In fig. 2, I have hardly had the jaw perpendicular when 

 drawing it, as it does not sufficiently express the great height 

 of the inner range of the molars over their outer edge, which 

 a cross section would have better shown ; but as the specimen 

 is gone on board, I cannot now make itf."

t The specimen represented in figures 2 and 3 was exiiibited at the 

 meeting of the Geological Society on Dec. 6, 1837. We have slightly al- 

 tered Col. Colvin's description, in order to make it correspond with the 

 figures in Plate II, which are a part only of those given in the Journal 

 of the Asiatic Society. — Edit.
