I have already dealt with this species and its geographical 
races at some length in the [bis 1919, p. 205, and it is therefore un- 
necessary for me to go into further detail here. All the specimens 
collected by Mr. Herbert agree well with Blyth’s intermedius, which 
only differs in being smaller. The average wing measurement for 
159 specimens of tntermedia is 144.4 mm., whilst Mr. Herbert's 
birds have wings ranging from 135 to 149 mm., and averaging 
143 mm., the two smallest birds coming from Samkok. 
The average Wing measurement for 7. j. javanensis is under 
130 mm.

This specimen dogs not agree with the rather doubtful 
form described by Hesse under this name. It is said to differ from 
typical G. rafflesi from Sumatra, in having red upon the upper tail- 
coverts and also in being much bigger. 
In size the two forms do differ to some extent, nine Sumat- 
ran birds having a wing averaging 138 mm., whilst thirty-nine 
Peninsular birds have the same 134 mm. Mr. Herbert’s specimen 
has a wing of 150 mm., but no red upon the upper tail-coverts. 
This latter characteristic seems to be a very uncertain one, 
Of the series in the British Museum, some ten adult birds have no 
tinge of red, whilst the other ten have it to a greater or less extent. 
On the other hand, one so-called Sumatran skin has this red tinge 
quite apparent. 
More skins from Sumatra are badly wanted, for of those 
in the Museum the majority have only got dealers’ data tickets, 
and only one has an original collector's ticket. Two specimens, 
moreover, look suspiciously like Malaccan dealers’ skins, and one 
cannot Jay down any sound diagnosis on material of this nature,
