RENDAHL, BIRDS FROM THE PEARL ISLANDS. 45 



Pileum mouse gray with some brownish tinge, margined 

 laterally by an indistinct dusky line, a paler superciliary stripe 

 indistinct and not extending behind eye; rest of upper parts 

 citrine, more brownish on interscapulium and hindneck; chin, 

 throat, median portion of chest and breast white with a light 

 shade of gray (påle gull gray ) ; sides and flanks between olive- 

 yellow and reed yellow; under tail-coverts, under wing-coverts 

 and axillaries between picric yellow and baryta yellow. 



As to the measurements, this specimen is greater than 

 what was stated for the female, agreeing more with the measure- 

 ments found in the male. It is, however, possible, that the 

 present bird was wrongly sexed by Dr. Bovallius. 



Measurements: wing 74,5, tail 56, tarsus 17,9, middle toe 

 without claw 11, exposed culmen 13.
