(2) That the actual mouutaiu fauna i« couijwsed of two elemeuts — 

 viz., 



(a) Coutiueutal, 



(b) Sumatrau, 



(rt) is largely in excess aud consists of species, fov the 

 most part, identical or only sliyrhtly differentiated 

 from the congeneric forms in Teuasserim and 

 Burma at similar elevations ; 



(b) is less dominant and comprises species identical 

 with or verv closelv allied to West Sumatrau 

 mouutaiu species. 



(3) That the connection with the Borneau mountain fauna is very 

 distant. "We may also infer that, at some geological epoch by no 

 means distant, the land area of the Peninsula was very much less than 

 is at present the case, and that the connection with Teuasserim has 

 l>een continuous or only interrupted for very brief spaces both in tiuie 

 aud distance. 



(4) That there has been a direct land connection with Sumatra, also 

 in comparatively recent times. 



(o) That the southern portion of the Peninsula — from some point 

 N. of the mouth of the Muar Kiver, including Mt. Ophir, and the area 

 on the east side of the Peninsida, south of the Pahang Eiver, at its 

 confluence with the Triang — has been at some very recent time discon- 

 nected with the mainland. This is shown, by the entire absence of all 

 Teuasserim and endemic species of birds, and by the fact that the line 

 roughly indicated is the southern boundary of such continental 

 mammals, as Sc. concolor and Sc. macddlandi ; while it is the 

 northern limit of such insular forms as Sus vittatus and Sc. penin- 

 eularis.
