• We regard the grey forms of Brachypodius as common mutations, but 
it is curious that they are unknown in some areas occupied by the species. 
* There is no difference in colour between many fresh skins of melano- 
leucos and "proximus". 
a The Malaysian subspecies of Criniger are very difficult to combine 
into species and the present attempt is, frankly, little more than suggestive. 
A significant feature is that only in the Malav Peninsula does one meet with 
two forms in any one place and that even here they are largely mutually 
exclusive. C. tephrogenys is common in the lowlands throughout the whole 
length of the Peninsula, C. sacctdatus only occurs in the south of the Penin- 
sula at high elevations. C. ochraceous occurs only in the north, but it 
overlaps the range of tephrogenys. Were it not for this it would be possible 
to regard all Malaysian forms as representatives of one widely-spread species.
