' The affinities of some of the Arbotophila forms of South-eastern Asia 
are difficult to discover as the genus shows an unusually strong tendency to 
produce well-marked geographical representatives. Robinson (Birds Mai. 
Pen. it, 1928, p, 8 ) has stated that the nearest ally of campbelli is atrogularis , 
but we think that the former is the Malayan representative of brunneopectus . 
A. rolli , javanica, and hyfer ythra are other Sunda Island forms of the same 
‘ ‘species’ 1 : Javanica although very distinct in colour is linked to brunneo- 
pectus by some richly coloured examples of campbelli. The presence of two 
very distinct sub-species in Java is awkward, but orientalis is only found 
in the east of the island. A, rubrirostris seems nearest to .4. davidi of 
Cochin China.
