FROM JAVA AND FROM SUMATRA, 209 
other localities, being evidently different from the javan 
form, must receive a new name. 
When cataloguing some years ago this species, it has 
already struck me, that specimens from Java are not so 
brightly coloured as specimens from Sumatra, Banka and 
Malacca. Dr. Hartert, being in Leyden some time ago, 
thought to have made the same observation with the ma- 
terial, he had had in his hands. I now received in the col- 
lection of Mr. Jacobson a specimen from Java, which is 
also less vividly coloured than specimens from Sumatra 
etc. I have now before me four adult birds from Java 
and several adult ones from Sumatra, Banka, Borneo and 
Malacca. Though the material from Java is not very 
large, yet it is sufficient to prove the differences between the 
Java bird and those from other localities. The typical 
Eurylaimus javanicus Horsfield occurs only on Java, whe- 
reas the form from Sumatra, Banka, Billiton, Borneo, 
Malakka and probably from other parts of the continent 
belongs to a different subspecies, which I herewith name, 
in honour of Dr. E. Hartert of the Tring Museum: 
Eurylaimus javanicus harterti nov. subsp. 
Type: oO, Deli, N. Sumatra, May 1884, Coll. Dr. B. Hagen. 
This subspecies is similar to Murylaïmus javanicus Hors- 
field from Java, but breast and vent are much more dark pur- 
plish vinous; the under tailcoverts are purplish vinous, 
not pure yellow or yellow with a slight vinous tinge as 
in all our birds from Java. Already Horsfield in his des- 
cription of the type-specimen ') said that the crissum is 
yellow and also Temminck ”) described the under tailcoverts 
as pure yellow, though, it must he said here, he recorded 
the species from Java, as well as from Sumatra. Vorderman ®), 
who gave the description of a male from Goenoeng Salak, 
W. Java, called the under tailcoverts light yellow.
