* It is certain that more genera are recognized here than is necessary, 
but although several authors have made bold attempts to lump the palaearctic 
genera, the tropical groups have not been included in their reviews. We 
have, therefore, chosen to be conservative rather than inconsistent but it 
may be noted that of the genera recognized here Hartert has already merged 
Hemic heUdon, Alseonax Siphia, Cyornis f Poliomyias f Zantkofygia t and 
Cyanopiila. u MuscUtm 7> is here placed in the Laniida for we do not see 
how it can be separated from Packycephaia ,

from Borneo but they are all really H. sibirica. Some Malaysian birds may 
be H. s , tncerta La Touche (North China) which we have not seen,
