64 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



were in breeding condition. The Rio Calovevora record is from an 

 immature bird taken by Benson. 



With an excellent series of specimens taken in Chiriqui and in 

 Bocas del Toro I find that birds from the two areas both represent 

 nigrifuniosa though currently those of Chiriqui have been placed 

 with chapmant. They show only very slight variation toward that 

 race. 



(The author's separates of the paper in which nigrifumosa was de- 

 scribed, through a printer's error, had the pages wrongly numbered, 

 the reference in the separate to this form being listed as on page 181 

 instead of 180 as in the original source.) 



SYNALLAXIS BRACHYURA CHAPMANI Bangs and Penard 



Synallaxis brachyura chapviani Bangs and Penard, Bull. Mus. Comp. Zool., 

 vol. 63, June 1919, p. 25. (Jimenez, Valle, Colombia.) 



Characters. — Definitely lighter colored throughout, the chestnut 

 of crown and wings being paler, the back lighter brown, and the 

 under surface lighter gray, with the white on the throat more exten- 

 sive. The average size is very slightly greater. 



Measurements. — Males (10 from the Canal Zone, Darien, and 

 San Bias), wing 56.0-65.3 (59.2), tail 67.6-81.7 (74.3, average of 

 9), culmen from base 15.7-17.5 (16.4, average of 9), tarsus 21.4- 

 24.4 (22.8) mm. 



Females (11 from San Bias and Darien), wing 55.6-60.3 (57.8), 

 tail 65.4-71.8 (69.8. average of 9), culmen from base 14.7-16.6 

 (15.8, average of 10), tarsus 21.4-23.0 (22.3) mm. 



Resident. Rare in the lower Chagres Valley in the Canal Zone; 

 fairly common in western San Bias near Mandinga ; common in 

 southeastern Darien on the upper Rio Jaque. 



The first record of this race for Panama is by Sclater and Salvin 

 (Proc. Zool. Soc. London, 1864, p. 354) of specimens received from 

 McLeannan at Lion Hill. There are three from this collector in the 

 British Museum (Natural History) and two in the U.S. National 

 Museum. Lawrence (Ann. Lye. Nat. Hist. New York, vol. 7, 1861, 

 p. 319) quotes a note from Galbraith, collecting with McLeannan, that 

 they were common. Bangs (Proc. New England Zool. Club, 1900, 

 p. 26) reported five taken at the same locality in March 1900. They 

 now are rare, as the last specimen record is by Goldman who 

 collected an immature female there February 6, 1912. At Mandinga,
