the tail feathers occur on both webs of the outer tail feathers; 
confined to Aracan and North Tenasserim; C. macrorhynchus 
lemmiscatus (Raffles), syn. C. malaccensis, Salvad., in which the 
white bars are well marked but occur on the inner webs only; 
found in the Malay Peninsula, Sumatra and the smaller 
intervening islands, and C. macrorhynchus macrorhynchus, in 
which the white on the tail is practically obsolete, confined to 
Borneo. 
This character however appears to be extremely variable, 
for several specimens submitted to us by the authorities of 
the Sarawak Museum coming from that State have the white 
as strongly pronounced as in many skins from the Malay 
Peninsula, which was evidently also the case with the collec- 
tions of the Dutch Scientific Expedition to Central Borneo 
(vide Buttikofer, Notes Leyden Mus. xxi, p. 184 (1900)). 
The above four birds have the white marks very faint, 
more so than in any Malayan Birds, which is also the case 
with certain of Klaesi’s specimens from the Padang Highlands 
(Buttikofer Joc. cit.) and with others collected by Abbot in 
Tapanuli Bay. é; 
Our specimens from Pasir Ganting may be regarded as 
topotypical of C. macrorhynchus lenmiscatus, which was pro- 
bably collected in Bencoolen, and the question arises whether, 
in view of the above facts, they should not be regarded as 
identical with the Bornean race, which is typical C. macror- 
hynchus. 
On the other hand, birds from Eastern Sumatra and the 
Lampongs appear to have the white on the tail strongly 
marked and to agree with those from the Malay Peninsula. 
But Western Sumatra, west of the main range, is an old 
land surface, while Eastern Sumatra is largely alluvial land of 
recent origin. It is therefore quite possible that the typical 
form may have existed in Borneo and West Sumatra, long 
prior to the deposition of the eastern area which may have 
been subsequently colonised from the Malay Peninsula, the 
mountains forming an effective barrier to the race inhabiting 
their western slopes. This would account for the occurrence 
of two closely allied forms in the same island. If this view is 
correct Eurylaimus lemniscatus becomes a pure synonym of 
C. macrorhynchus (Gm.), while the bird from the Malay 
Peninsula, Eastern and Southern Sumatra must be known as 
C. macrorhynchus malaccensis, Salvad.
