FOSSILS FKOM PEEIM ISLAND.

relief of the ridges, tlie depth of the muscTilar depressions, 

 and especially by the circumstance that the posterior articu- 

 lating surface is completely synostosed with the body of the 

 bone, which is not the case in young animals. With this 

 united correspondence in form, size, and other particvdars, I 

 have little hesitation in referring the Perim Island fossil to 

 the second cervical vertebra of the Gamelopardalis Sivalensis. 

 This specimen is from the collection sent by Captain Full- 

 james to the Geological Society.

The next of these remains to be noticed are of great in- 

 terest, as they appear to indicate a large and peculiar form 

 of Ruminant, nearly equalling the Sivatherium in size, but 

 at the same time essentially different. The remains consist 

 of two fragments of the left side of the upper jaw, including 

 the entire series of the s\iperior grinders.' Although pro- 

 bably of the same species, they are certainly not derived from 

 the same individual. The first fragment (fig. 1) is from 

 the collection sent by Captain Fulljames to the Geological 

 Society. It contains the three false or premolars nearly 

 perfect, together with the broken remains of the first true 

 molar. The surface of the enamel (fig. 2) shows the 

 rugosely furrowed character, which is found in the Siva- 

 therium ; but the whole of the teeth in the fossil are at once 

 distinguished from those of that genus by the absence from 

 all of them of the sinuous plaited flexures, which the inner 

 crescent of enamel presents in it ; they also want the basal 

 collar or ' burr ' on the inside, which is seen in those of 

 Sivatlieriun. With these discrepancies, which are of consider- 

 able importance in the Ruminantia, from the constancy of 

 such modifications in the different groups of this order, the 

 premolars of the fossil correspond in general form, and in 



' The following remains of Brama- 

 therium are described by Dr. Falconer in 

 the Catalogue of the Museum of the 

 Asiatic Societj' of Bengal : — 



No. 38. Perim Collection. Lower 

 ja-w, left side, in two pieces, containing 

 2nd and 3rd true molars, truncated in 

 front and behind. 



No. 39. Lower jaw, left side, con- 

 taining four molars, worn, but more or 

 less broken. 



No. 40. Proximal imgual phalanx 

 of left leg. It corresponds almost 

 exactly in size and in proportion with 

 the same phalanx of the fore leg of 

 existing Giraffe in the Asiatic Society's 

 Museum. 



No. 41. Horn of the Bramatherium (?) 

 resembling the horn of Sivatherium, 

 figured in Journal of the Asiatic Society, 

 but different. This is a specimen of 

 very great interest. 



No. 42. Portion of the shaft of a long 

 bone, apparently the tibia, left side, of a 

 ruminant resembling the Giraffe and 

 hence inferred to be of Bramatherium 

 from its larger size. 



For an account of the bones of the 

 anterior and posterior extremities of 

 Bramatherium the reader is also referred
