IN the present Catalogue of the Fossil Remains of Mammals and Birds 

 in the Museum of the College, the specimens have been severally 

 referred to the species to which they belonged, the bones named ac- 

 cording to the place in the skeleton, and the teeth according to the 

 position in the dental series which they originally occupied. A brief 

 exposition of the principal characters of the fossil, and of the dif- 

 ferences which it presents in comparison with its nearest existing 

 analogues, has been subjoined where required by the rarity or singu- 

 larity of the specimen ; and in the case of the remains of species im- 

 perfectly known or new to science, the descriptions are pursued to the 

 details requisite to establish the characters and affinities of such spe- 

 cies, and to serve for the identification of similar fossils which may 

 hereafter be discovered. In some instances the determination of the 

 precise affinities of the fossil has required microscopic investigation of 

 the tissues, as in the teeth of the Glyptodon, Mylodon and Megatherium. 

 The matrix or geological formation, and the locality from which 

 each specimen has been obtained, are subjoined to the determination 

 or description, except in a few instances of the Hunterian specimens, 

 where such records had not been preserved. A particular account 

 has been added, from the best authorities, of the more remarkable lo- 

 calities, as the ossiferous caves of Gailenreuth, Kuloch, Oreston, &c.
