Judging from its rarity in collections we conclude that this species is an 
inhabitant of the mountains. The exact localities of the specimens obtained 
by Meyer and those in the Darmstadt and Leyden Museums have not been 
recorded, but the Drs. Sarasin obtained it in the crater itself of Mount Klabat 
and in the neighbourhood of 'I'omohon c. 2500—3000 ft., and our native collec- 
tors sent It only from the neighbourhood of Lake Tondano, which lies at an 
altitude of over 2000 feet. Its stomach was found by the Drs. Sarasin to contain 
insects. 
P. sulfunventer belongs to the group of Pachycephalae which have been 
separated as a distinct genus, Hploterpe Cab. {= Musdtrea Bljth , of the same 
date, 1847), a group in which the sexes are alike in coloration. Over a dozen 
spemes of this group are now known, ranging from Bengal throughout the East 
Indies as far as New Guinea, viz: 
Burmah and the Andamans to 
P.grisola iBlyth), [Muscitrea ap. Oates) 
Borneo, Java and Lombok; 
P. hnmneicauda (Salvad.), Sumatra; 
P whiteheadi Sh. [P. plateni W. Bias.), Palawan; 
P. philippinensis Tw., Philippines; 
P. homeyeri W. Bias., Sooloo; 
P. hypoxantha Sh., Borneo ; 
P. sulfuriventer Wald., N. Celebes; 
P.meridiomdis Biittik., S. Celebes; 
P. teijsmanni Biittik., S. Celebes and Saleyer; 
P. Orpheus Jard., Timor, Saleyer, Samao; 
P.phaenonota (S. Miill.), Moluccas; 
P.griseiceps Gray, Papuasia; 
P.jobiensis Meyer, Jobi; 
P. miosnomensis Salvad., Miosnom; 
to which some others would have to be added in a complete Ust of the group.

tending higher, and being much brighter. The bill is likewise more powerful”
