FOSSIL EEMAINS FROM AVA. 413 



Of the Pachydermata there are bones belonging to two 

 genera, the Rhinoceros and Mastodon. 



ISTo. la. Is a fragment consisting of a longitudinal and 

 vertical section, of a molar tooth of a Mastodon, with a por- 

 tion of the attached jaw, and a nearly entire fang. The 

 characters are not suificientlj marked to determine the 

 species, but it seems to approach most nearly the Mastodon 

 latidens of Mr. Clift (Geol. Trans, vol. ii. p. 11). 



No. 16. Is a portion of the middle of the femur of a 

 Mastodon. 



No. 2 a. Is a portion of the lower jaw of the left side of 

 a Rhinoceros, containing a perfect tooth, which has been 

 accidentally divided. It has belonged to an animal now 

 extinct, and of larger size than the Rhinoceros unicornis of 

 this country. The form of the tooth is different from that 

 found by Mr. Crawford, but as the characters vary, from 

 wearing, with the age of the animal, it is no easy matter to 

 determine whether or not it belongs to a different species. 

 It resembles very closely in form the Rhinoceros eriques of the 

 ' Ossemens Fossiles ' of Cuvier. 



Nos. 3 a, h, and c are vertebrae from different parts of the 

 spinal column of Crocodilece. Some of the bones carried to 

 Europe were found to belong to the Leptorhynchus of the 

 Ganges, or a species very nearly allied. 



Nos. 4 a, h, c, and e are osseous fragments of two large 

 genera of Turtle, the Emys and Trionyx. The remains of 

 these animals bear a large proportion to the other bones. 



There are several specimens, comprising the greater part 

 of the collection, to which no names have been attempted to 

 be given. Soine of them are well marked, and the in- 

 dividuals to which they belonged might be hazarded with a 

 tolerable degree of confidence ; but when the evidence fell 

 short of certainty, it appeared better to present the bones 

 without attempting to name them than run the risk of 

 giving misnomers and misleading others. 



A correspondence has been discovered between a specimen 

 from the Himalayahs and those of the Trionyx or Emys from 

 Ava ; there can be little doubt that when we have an op- 

 portunity of making a comparison of the fossil bones from 

 both places further coincidences will be brought to light.
