INTRODUCTION. 



As a full Introduction has been given to the First Part, it is only 

 necessary on the present occasion to add a few supplemental 

 remarks. 



In order to avoid extending the Catalogue to an unreasonable 

 length, it has been considered advisable to omit all reference to the 

 majority of the specimens contained in the Cavern Collection, at the 

 entrance to the Fossil Mammalian Gallery, as, in most instances, 

 these are but duplicates of specimens from other localities. For 

 the same reason, in cases where the number of specimens of the 

 remains of any one species is excessively numerous, only the more 

 important of such specimens have been introduced into the Cata- 

 logue. Similarly, in cases like the Siwaliks of India and the French 

 Phosphorites, where there are great numbers of species of Artio- 

 dactyle Ungulates, and it is very often apparently impossible to 

 refer individual bones even to their respective genus, such specimens 

 have not been catalogued here, as nothing would be gained by so 

 doing. 



Mention may be made of a few fossil localities noticed in the 

 present part, which are not given in the table on pages x, xi of 

 Part I. ; but before doing so, it may be observed that the position of 

 the Georgensgmlind 1 beds as given in that table should be transferred 

 from the Upper Miocene to section b of the Middle Miocene 2 . The 

 Lower Pliocene of Cucuron (Vaucluse) is equivalent to that of Mont 

 Leberon. The beds at Elgg (Zurich), Switzerland, correspond to 

 those of Kapfnach. From the comparatively unaltered condition of 

 many of the specimens in the Museum, and the circumstance that

2 These beds were classed with those of Eppelsheim and (Eningen, on the 

 ground that they were so placed by Schlosser in the ' Palajontographica,' 

 vol. xxxi. p. 96 (1884), who has subsequently (Neues Jahrb. 1885, vol. ii. 

 pp. 136-144) indicated their true position.
