3. Descrij)tion of some M.AMMAi.1 AN Fossils /row^ the Red Crag 

 o/ Suffolk. By Prof. Owen, F.R.S., F.G.S. 



Since my description of the mammalian fossils of the Red Crag, 

 collected by Sir Charles Lyell at Newbourn, Suffolk, in 1840*, and 

 the publication of the ' History of British Fossil Mammalia,' in which 

 these and subsequently discovered Cetacean Crag fossils were figured, 

 I have visited several localities where the Red Crag is worked for 

 phosphatic nodules, in Suffolk, and have myself collected, and have 

 received from other collectors, numerous specimens of mammalian 

 remains, from the Red Crag, of which I have selected the following 

 as most worthy of being described. 



Genus Rhinoceros. 



There is some difficulty in determining the species of Rhinoceros 

 by detached fossil molar teeth — the only recognizable parts of the 

 genus that I have yet obtained from the Red Crag of Suffolk. 



Most of the detached molars of Rhinoceros from this formation 

 appear by their size, want of roots, and indications of absorbent action 

 at the base of the crown, to have belonged to the deciduous series of 

 teeth, and to have been shed by young individuals ; and the milk- 

 teeth are less characteristic even than the permanent ones, as indeed 

 most structures of the immature period of life partake more of the 

 general and less of a special character than those of the adult. There 

 are, however, specimens of the permanent teeth sufficiently cha-
