gatus. 
Of the forms that are not peculiar to Sumatra occurring 
in this zone 25 are found also in Java, 26 in Borneo and 33 in 
the Malay Peninsula, or, put somewhat differently, of the 
total of 81 species 46 also occur in Borneo or are represented - 
there by closely allied forms, 18 are found in Java, or have 
their nearest telatives there but are not met with in Borneo, 
I5 are identical with or nearest to continental forms which 
have not spread to the Indo-Malayan Ids., while two species, 
which are peculiar to the island of Sumatra, have no very 
close relatives. 
Of the 46 species which are represented in Borneo, very 
many also occur in Java so that in this zone, also though not 
quite to the same extent as at higher altitudes, the Javan 
element may be said to be predominant. 
The Himalaic and Tenasserimese species have*increased 
largely and are here practically equal to those found in Java 
only. 
Dr. Sharpe gives 43 species as inhabiting the correspond- 
ing zone of Kinabalu, viz., 3-4,000 feet, though this is narrower 
than the one we have taken for Korinchi, 21 species are given 
as not ascending higher and of these 13 are represented in 
Korinchi, leaving the following nine :-— 
Rhinomytas rificrissus. Allied to a Philippine species. 
Geocichla aurata. Intermediate between a Malayan and 
a Javan species. 
Staphidia everett. A member of a continental genus not 
elsewhere represented in the Indo- 
Malayan region.
