2l6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I50 



I did not find these birds at Jaque, Darien, in 1946 and 1947, and 

 there are no present records for the species on the Pacific coast south 

 of Garachine. To the south and east this race ranges across northern 

 Colombia and northern Venezuela. It is fairly common along the 

 Chucunaque and the Tuira, less so in the western area of the San 

 Bias coast. When perched near at hand it is possible to note the 

 gray bands on the tail, which are a field mark to distinguish this race 

 from petulans of farther west, in which these marks are rufous. 



Todd and Carriker (Ann. Carnegie Mus., vol. 14, 1922, p. 155) 

 describe two eggs of this race, collected at Bonda, Magdalena, Colom- 

 bia, by H. H. Smith, April 13 and 18, 1898, as "dull grayish white, 

 specked and blotched with pale chocolate, sparsely over the small end, 

 more thickly about the middle, while the large end in one is palely 

 washed and mottled with chocolate over the greater part of the 

 surface; in the other, the large end is more heavily washed with a 

 much darker shade of chocolate and heavily streaked with lines of 

 dark umber. They measure 42.5x35 and 42x34, the eggs being 

 oval." 



J. Parker Norris, Jr. (Ool. Rec, vol. 6, 1926, p. 36), had one egg 

 of this subspecies, taken from a nest about 10 meters from the 

 ground in an upright crotch in tree in "semi-savanna country" near 

 La Tigrera above Santa Marta, Colombia. The tgg, described as 

 "brownish-white marked with an indistinct cap of pinkish brown at 

 the large end," measured 45.5 by 36.3 mm. 



Sets that I have seen of other subspecies from Tamaulipas, Mexico 

 (5. m. griseocauda) , and from Rio Grande do Sul, Brazil {B. m. 

 magniplumis) , were of two eggs each. 



The type locality in the original description was given as "Santa 

 Marta Mountains." The race was described from a female taken by 

 W. W. Brown, Jr., in the Museum of Comparative Zoology labeled, 

 "Colombia (Santa Martha) Mts. January 16, '98." From what is 

 known regarding the itinerary of the collector, on the date in question 

 he was located at Bonda, a village a few miles east of Santa Marta.
