2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.98 



indistinctly with vinaceous buff ; primaries and secondaries fuscous, 

 edged narrowly with pale olive-buff, these light markings prominent 

 at the centers of the sixth, seventh, and eighth primaries ; dorsal 

 surface of rectrices fuscous, the outer one margined all around with 

 pale olive-buff; chin white; throat ivory yellow, the feathers white 

 basally ; a broad band of fuscous across lower f oreneck, continuous 

 at sides with the dark color of the sides of the head ; behind this a 

 narrower band of white, washed lightly with cream-buff ; behind 

 this, a band of fuscous-black across the upper breast, narrower than 

 the anterior dark band, and somewhat irregular and broken centrally ; 

 rest of under surface white washed with cream-buff, with a line of 

 spots of fuscous-black extending from the sides toward the central 

 part of the breast as indication of a third dark bar which, however, 

 remains broken in the center ; flanks spotted with fuscous and. fuscous- 

 black ; under wing-coverts cream-buff ; inner webs of primaries at 

 base dull white ; of secondaries ivory yellow ; under tail-coverts cream- 

 buff. Bill black, tarsus and toes dull brownish black (from dried skin). 

 Iris indicated by collector as yellowish buff. 



Measurements. — Type, male, wing 91.5, tail 85.3, culmen from base 

 35.7, tarsus 19.0 mm. 



Males (3 specimens), wing 89.8-91.5 (90.4), tail 83.4-85.3 (84.1), 

 culmen from base 34.2-35.7 (35.1), tarsus 19.0-20.4 (19.6) mm. 



Females (6 specimens), wing 89.7-93.3 (91.3), tail 86.7-89.3 (88.5), 

 culmen from base 35.0-37.3 (35.7), tarsus 19.0-22. 1 (20.1) mm. 



Remarks. — Separation of the Margarita Island form is made after 

 comparison of nine specimens from the island, two in the National 

 Museum and seven loaned by the Field Museum, and nine from the 

 mainland of Venezuela. The paler coloration is easily evident in series 

 and though some individuals approach rather closely, all that 1 have 

 seen can be allocated properly without particular difficulty. 



It may be noted that Ridgway 2 observed the paler coloration of the 

 Margarita Island bird but did not have material available on which 

 to make the separation.
