64 Notice regarding Fossil Remains Jbund in Ava. 



by deep transverse furrows and ridges, the latter divided into 

 two or liiore obtuse pyramidal points or mammillae. 



It was this singular appearance which made the mastodon 

 a long time be considered erroneously as a carnivorous animal. 

 Five species of the genus mastodoix are supposed by Cuvier to 

 have been discovered, and I imagine the bones now under con- 

 sideration will be found to constitute a sixth species ; for the mo- 

 lares, on which he principally rests for his specific distinctions, 

 differ very materially from the representations which he has 

 given of the ascertained species. The mastodon of Ava, if it 

 be a distinct species, will be found equal in size to the great 

 mastodon of the Ohio, which is reckoned to be equal in size to 

 the Indian elephant. A grinder, which I examined, measures, 

 in circumference, between sixteen and seventeen inches, and the 

 circumference of a humerus round the condyles is not less than 

 twenty-five inches. Several of the grinders and bones, however, 

 apparently of an animal of the same species, are much smaller 

 than these, but this is probably on account of their belonging 

 to younger individuals. I need hardly observe that our mas- 

 todon, like others of the same genus, and all the species of the 

 elephant, had tusks. Several fragments, but no entire tusks, 

 are in the collection. 



" The next most remarkable remains are those of the fossil 

 rhinoceros. There are several molares of an animal of this ge- 

 nus in the collection. Cuvier describes four species of the fossil 

 rhinoceros to have been ascertained, all differing from the living 

 species. The bones, now found, bear a striking resemblance to 

 one of the species represented by Cuvier ; but the molares are 

 considerably larger than any of those which he has represented. 

 The collection seems to me to afford evidence of the existence 

 of two other animals of the same family with the elephant, mas- 

 todon and rhinoceros ; at least, teeth, which I have seen in it, 

 exactly resemble two species of a genus represented in the work 

 of Cuvier, and to which he gives the name of Anihracotherium. 



" The other teeth of quadrupeds which exist, and which I am 

 able to recognise, are those of an animal of the horse-kind, and 

 those of an animal of the ruminant family, apparently of the 

 size of the buffalo. 



" Among the remains are numerous specimens of those of a
