it is probably younger than the other specimen. ‘The species is rare 
in the Malay Peninsula. We have half a dozen specimens from Trang 
to Selangor shot in December, January or April.

The specimen sexed [2] by the collector (but almost certainly 
an immature male, as it has a few blue feathers on the forehead) pre- 
cisely agrees with the immature males from Chong Hill, Trang, obtain- 
ed by us in December 1910.

We have dealt elsewhere with Gerygone griseus, founded on a 
single specimen from Kok Lak. The form appears quite inadmissible 
even as a subspecies, but it is futile to attempt to divide the species 
into local races based on single individuals.
