Fairly common on both the above islands.
A comparison of the above series and seventeen other
specimens from various parts of the Malay Peninsula
with nine specimens from Eastern Java (Idjen massif, nr.
Banjoewangi) show that it is readily possible to distinguish
the Malayan and Siamese from the typical }a\an form, in
that, both in males and females the rump and upper tail
covert are concolorous with the back and not strongly tinged
with zanthine orange. Dimensions are practically identical.
Types: Adult mule. Lamra, Trang, Siamese Malaya,
collected on January 10th. 1910.
Adult female: Gunong Jerai (Kedah Peak), Kedah,
2,800 ft. to 3,500 ft. collected on December 2nd. 1915.
Remarks: It is possible that Oreskios gouldi quoted bv
Ogilvie Grant, floe, at.) as of Bp. Coiisp. Vol. Zyg. p. 14
(1854) applies to this bird, but I have no access to the
reference. The name, however, is of earlier date as it is
quoted by Bonaparte in 1850 (Coiisp. Av. 1. p. 1511 as a
synonym of Trogon oreskios and attributed to Swainson.
though I cannot trace the quotation. I prefer, therefore,
to regard it as a nomen nudum.
