however so small that the mountain fauna is correspondingly limited 
aud it is therefore not safe to draw any deductions from the absence 
or presence of particular species. 
Many forms strictly confined to the zone above 3,000 feet 
in the south of the Malay Peninsula here occur at elevation of 
1,000 feet or under while certain species such as Cyanops oorti 
and Oriolus consanguineus of insular facies, common everywhere in the 
hills of Selangor and Perak, are not met with on Kao Nawng and 
presumably do not occur. 
The following species not hitherto recorded from the Malay 
Peninsula were collected : 
Pseudotantalus leucocephalus (Peun.) ; 
Cyanops davisoni (Hume) ; 
Anthipes submoniliger, Hume ; 
Anthipes olivacea (Hume) ; 
Cryptolopha youngi, sp. nov. ; 
Thringorhina guttata (Tick.) ; 
Pnoepyga pusilla, Hodgs. ; 
Athopyga sanguinipectus, Wald. 
Without the active co-operation of the local authorities jungle 
- travel in the Siamese portions of the Malay Peninsula is practically 
impossible to a stranger. Our most hearty thanks are therefore due, 
in the first place to H.R.H. Prince Damrong, Minister of the Interior, 
Siam, who provided us with the necessary introductions, and in the 
second to the Acting Governor of Bandon and to the amphurr™ of 
Lampum, who treated us most courteously and took an infinity of 
trouble in securing the large amount of transport that we required. 
Without their aid we should have been tied to the line of the railway 
and would have obtained no results of any particular interest.

These jungle partridges are apparently fairly common in the north 
of the Peninsula, though they are extremely rare south of the latitude 
of Taiping in central Perak. Near Ban Kok Klap they were very 
numerous in dry jungle but very wary and almost impossible to 
approach. Mr. Seimund, who obtained one specimen, describes the 
note as a soft low double whistle. The small native boys occasionally 
shoot them with pellet bows. They make excellent eating.
