Birds of the PliUippine Islands. 109 



female specimen^ and it is unfortunate that up to the present 

 time Mr. Whitehead has not succeeded in obtaining the male 

 of either species. O. isabeUce, though bearing a strong 

 resemblance to 0. albiloris in general coloration and appear- 

 ance, may be easily recognized by its larger size, the bill 

 being twice as stout and brownish black instead of dark red ; 

 the colour of the lores and chin is bright yellow ; the under- 

 parts uniform golden yellow_, with scarcely any trace ot 

 dark shaft-stripes on the flanks ; the outer tail-feathers 

 show no trace of the black subterminal spot characteristic of 

 0. albiloris ; while the shape of the wing in the two birds is 

 quite different. 



2 adult. General colour above dark yellow, slightly tinged 

 with olive, especially on the head and nape ; primaries and 

 secondaries brown, margined on both webs with yellow, the 

 innermost secondaries and scapulars entirely dark yellow ; 

 lores, narrow superciliary stripes, chin, throat, and rest of 

 the underparts uniform bright yellow, brightest on the belly 

 and under tail-coverts ; tail dark brownish yellow, the outer 

 feathers very narrowly tipped with pale yellow.

O. isabelloi. 4th primary longest ; 2nd=10tli ; and the 1st 

 about ^ the length of the 2nd, 



0. albiloris. 4th primary longest; 2nd = 7th; and the 1st

In the second collection made by Mr. Whitehead in the dis- 

 trict of Benguet there was an adult male Pericrocoius, most 

 nearly allied to P. yfam^nez^s from S.India and Ceylon. Though 

 I failed to identify it with anything previously described, 

 I did not give this bird a name, hoping that additional speci- 

 mens might be sent in Mr. Whitehead's siibsequent collections.
