Dr. Richmond has examined two of our Calayan specimens and 
confirms my identifications.

Some doubt has been raised as to the validity of Dr. Steere’s 
Tole guimarasensis, and after puzzling over a series from several 
islands I am not surprised that opinions differ on this point. 
Steere described the species from Negros, Guimaras, and Panay 
and it is quite probable that the Masbate /ole is of the same variety, 
although no comparison of skins has been possible. Bourns and 
Worcester consider guimarasensis not entitled to separation, while 
Grant agrees with Steere and says: “The much larger bill of this 
bird and the paler color of the throat are differences easily ap- 
preciated.” 
To settle the first point I have prepared a table of measurements 
of specimens from several islands and give the results in condensed 
form showing under each head extremes and averages. It will 
be seen that while the extreme dimensions overlap, the averages for 
Masbate-Ticao specimens are nearly all greater and never less than 
the averages for birds from Mariveles, Luzon. The only color 
difference seems to be that of the throat, which in philippensis is 
bright tawny rufous, while in guimarasensis the color is pale rufous, 
becoming quite dingy in worn specimens. April specimens from 
Benguet, Luzon, and from Ticao are used in the color comparison. 
The color difference is quite constant and taken with the larger 
size of guimarasensis seems to entitle that species to recognition. 
With the Verde Island birds I have been bothered not a little. 
They are in fresh plumage, having been taken in December and 
are therefore not strictly comparable with our specimens from 
Masbate and Ticao, which were taken in April, May, and June. 
The six specimens from Verde Island are certainly not philippensis 
but appear to be very closely related to the Masbate species, if not 
identical with it. The measurements of so few specimens are of
