22 BOURNS AND WORCESTER: PRELIMINARY NOTES. 



25. Hyloterpe major sp. nov. 



Adult male: General color exactly as in H. winchelli from which 

 it differs in having the white of the throat less sharply defined and 

 in its much larger size. 



Four males from Cebu measure 7.31 in length. Wing, 3.70. Tail, 

 2.97. Culmen, .80. Tarsus, .88. 



Three females from the same locality measure 7.00 inches in 

 in length. Wing, 3.69. Tail, 2.83. Culmen, .79. Tarsus, .87. 



Three males from Tablas measure in length 7.00 inches. Wing, 

 3.40. Tail, 2,79. Culmen, .75. Tarsus, .89. 



Habitat: Cebu, Tablas, Sibuyan. 



It will be noticed that the Tablas birds are slightly smaller than 

 those from Cebu. The same holds true of the Sibuyan birds. We 

 note also that the Cebu birds have the feathers of the thighs dark 

 brown faintly tipped with white while Sibuyan birds have the 

 same feathers light brown heavily tipped with white. The under 

 tail-coverts in the Cebu birds are usually not white but are washed 

 with brown, in one case heavily; but we note a good deal of variation 

 in the color of under parts in birds from the same locality, also that 

 the largest of our Tablas- Sibuyan birds are larger than the smallest 

 of the Cebu birds, hence do not think they can be specifically sepa- 

 rated. The distribution is curious, as H. winchelli comes between; 

 but this is only one of several instances of relationship between 

 Cebu and the Tablas -Romblon-Sibuy an group. 



26. Hyloterpe mindorensis sp. nov. 



Adult female. Above brown washed with olive yellow, faintly on 

 head, more heavily on back, the rump bright olive yellow. Scapu- 

 lars, wing-coverts and outer webs of tertiaries heavily washed with 

 olive yellow changing to olive brown on secondaries and primaries.

 of feathers above brown, below bright yellow. Lores and sides of 

 face ashy brown. Ear-coverts with distinct light shaft stripes. 

 Chin, throat and upper breast ashy grey, changing to olive brown 

 on sides of neck, breast and upper breast. Lower breast and
