Of these, with the exception of species previously men- 
tioned, only the following appear to be confined to Sumatra,

In this zone we reach the lower limit of the true moun- 
tain fauna and only the following fourteen species do not 
extend as far as sea level, though two, Garrulax bicolor and 
Melanocichla lugubris, were not found at higher elevations than 
the upper limit of the zone. 
1. Chalceurus chalcurus. 2. Dendrocitta occipitalis. 
3. Dicruropsis sumatranus. 4. Buchanga stigmatops phedra. 
5. Bhringa remfer. 6. Hemipus picatus. 
7. Garrulax bicolor. 8. Melanocichla lugubris.

11. Hapalharpactes macklott. 12. Cyanops oortt. 
13. Pstlopogon pyrolophus. 14. Ihopodytes tristis elongatus. 
The Javan element is here at its minimum, only three 
species, Nos. 5, Bhringa rvemifer, 10, Turdinulus epilepidotus 
dilutus, 11, Hapalharpactes mackloti, having their closest relations 
in that island; the continental element is strong, vide, 
8, Melanocichla lugubris, 12, Cyanops oortt, 13, Psilopogon pyro- 
lophus, all occurring in the Malay Peninsula, while certain 
species extend to Borneo or are represented there but are not 
found in Java, such as Dendrocitta occtpitalis, Buchanga stigma- 
tops phedra, Rhinocichla mitrata and Hemipus picatus. 
GENERAL CONCLUSIONS. 
The foregoing analysis of the collection enables us to 
formulate with some degree of confidence the following 
conclusions. 
A. The highest elevations of Korinchi Peak are inhabited, 
almost exclusively, by a fauna which to all intents and purposes 
is identical with that found on the higher elevations of the 
island of Java and the smaller islands to the east and is very 
much more distantly related to that of similar zones on 
Kinabalu. 
B. In addition to this Javan element, a small proportion 
of the species is of recent continental origin, occurring on the 
mountains of the Himalayas and the mountains of Tenasserim 
and the Malay Peninsula but not spreading to either Java 
or Borneo.
