172 BIRDS OF THE 
mandible red, inside of mouth and tongue black, naked part 
round the eye scarlet; feet grayish blue, sometimes tinged 
with green, soles ochraceous. 
Hab. Throughout Borneo, in the plains as well as in 
the mountain-forests. Count von Berlepsch, in his above 
quoted paper, was the first who stated the constant diffe- 
rence of the Bornean specimens from those from Malacca 
and Sumatra, which hitherto had been united under the 
specific name of Ramphococcyx erythrognathus. The principal 
differences consist in the shape of the nostrils, which are 
oblong in the Bornean specimens while they are circular 
in the birds from Sumatra and Malacca, and in the length 
of the red terminal part of the central tail-feathers which 
is constantly less in Bornean birds than in those from 
Sumatra and the Malay Peninsula. The length of wing and 
tail, said by von Berlepsch to be inferior in Bornean birds, 
does not differ constantly in the rich material at hand from 
Borneo and Sumatra. ri 
Count von Berlepsch, in his above quoted paper, also 
mentions the reasons why he re-unites the genera Ram- 
phococcyx, Rhinococeyx and Urococcyz, and Dryococcyx with 
Phoenicophaes, and J fully agree with the view based upon 
his arguments. I also confirm the difference in the sex of 
the present species, which holds well in all the numerous 
specimens which I have collected and sexed myself during 
my stay in Borneo, although this is not the case with the 
three specimens from the Upper Mahakkam, which are 
probably wrongly sexed by von Bérchtold.
