FOSSIL GENERA op the SUB-HIMALAYAS. 59 



stated to exist in the living species by Dr. Adams, twice the occipital con- 

 dyles' breadth equalling the breadth at the orbits. 



Figures 2a, 2b, 2d, PL V, and Fig. 6, PL IV, are taken from a speci- 

 men which is the only one of the kind hitherto met with. It is a fragment 

 from the jaw of some pachydermatous animal* ; but differs materially from 

 all with which it has been compared : further discoveries will it is hoped 

 throw light on this interesting fragment. 



Fig. 9, a, b, c, PL VII, is a fragment from the jaw of an animal sup- 

 posed to belong to the genus Sus. (Sus Sivalensis, Fal. and Caut.J 



Fig. 6, PL VII, molar of a small Hippopotamus. 



Fig. 7 and 10 a, b, molars supposed to belong to species of the Siva- 

 therium.^ 



Fig. 8, a perfect tooth, the lower part of which has a white enamel ; 

 the upper part is a dark brown cone, longitudinally striated — I have deli- 

 neated it in consequence of its dissimilarity to the drawings or specimens 

 of Saurian teeth which have come under my observation.| 



* The drawing of this fragment so much resembled Cuvier's plates of the Hippopotamus, 

 that I wondered at the author's misgivings on the subject, and wrote to interrogate Dr. 

 Falconer previous to putting the present page to press. Dr. F, however assures me that the 

 fragment undoubtedly does not belong to that animal ; but, as Lieuts. Baker and Durand 

 had rightly conjectured, to a new pachydermatous animal, to which Captain Cautley and 

 himself have from other specimens given the name of Chcerotherium : " the engraving is 

 imperfect, and so much like the Hippopotamus, that it might be easily mistaken. The dif- 

 ference in the original tooth however is well marked. There is no real trefoil on it ; the appear- 

 ance is spurious : the plane of wearing is oblique ; the spur is strongly bifid ; and the coUines 

 or mamillary processes are wide apart." J. P. 



f Dr. Falconer remarks on the engravings: Figs. 10, a, b. " they exhibit the form well, 

 but they do not give the characters of the surface of the teeth, which is striated reticularly with 

 rugous eminences." A tooth of the same kind, obligingly sent down by dak for my inspection, 

 exhibits these peculiarities very distinctly ; I hope shortly to have an opportunity of 

 engraving it. - J. P.
