Of the thirteen bird species, forming the list of the hosts, three, marked 
with asterisks, are species peculiar to this Island and many of the parasites 
found on them are new species. 
The mikado pheasant, Calophasis mikado of Mt. Arisan, the most interest- 
ing species of all Formosan birds, is parasitized by six Mallophagan species of 
which two are new species and the other four common to several other pheasants 
except one which differs so considerably from the type that it must be referred 
to as variety. From <Arboricola erudigularis (Phasianide) which is found 
throughout the Island at higher altitudes, five Mallophagan species were ob- 
tained, of which three were new species and two were known species, 7. ¢., 
Menopon pallescens Nitzsch and Lipeurus rubrifasciatus Piaget. 
None of the Mallophagan parasites of Campephagidee have hitherto been re- 
corded. Of this family our list contains two species, i. e. Pericrocotus griseigularis 
and Graucalus rex-pineti, and the former was found to be parasitized by 
Docophorus communis Nitzsch, the most widely spread species among Passeriforme 
hosts. rom the latter were taken two parasites, one of them being Lipeurus 
baculus common to doves and the other a new Goniocotes which was also found 
in the wedgetailed pigeon, Sphenocercus sororius. This unusual distribution 
may be due eitheir to the fact that these two host species have a similar
