472 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Measurements. — Males (10 from Chiriqui and Costa Rica), wing 

 66.0-73.0 (70.2), tail 54.5-60.9 (58.1), oilmen from base 14.7-16.7 

 (15.4, average of 9), tarsus 15.5-18.1 (17.0) mm. 



Females (9 from Chiriqui and Costa Rica), wing 62.3-67.5 (64.8), 

 tail 47.6-59.7 (54.4), culmen from base 14.0-15.1 (14.5, average of 8), 

 tarsus 15.2-17.6 (16.3) mm. 



Resident. Rare in the lowlands of western Chiriqui, where Arce col- 

 lected it at Bugaba and Divala (Salvin and Godman, Biol. Centr.- 

 Amer., Aves, vol. 1, pt. 28, 1884) and J. H. Batty took it at Boqueron 

 and David. The specimens at the American Museum of Natural His- 

 tory collected by Batty labeled Iguaros I., Medidor I., and Cebaco I., 

 all off the coast of Veraguas are probably falsely labeled. This race 

 also occurs in adjacent Costa Rica. 



Ridgely (in litt.) comments that this form is probably close to being 

 extirpated in Panama; he knows of no recent records. 



TACHYPHONUS LUCTUOSUS AXILLARIS (Lawrence) 



Chhrospingus axillaris Lawrence, 1874, Ann. Lye. Nat. Hist. New York, 10, p. 

 395. (Talamanca, Costa Rica.) 



Characters. — Male with white of wing coverts less in amount; some 

 with partly concealed yellow in center of crown. Female differs from 

 panamensis in having crown and nape like back, and from nitidissimus 

 in having throat yellowish like rest of undersurface. 



Measurements.- — Males (10 from Bocas del Toro and Costa Rica), 

 wing 64.0-68.5 (66.1), tail 54.2-59.3 (56.9), culmen from base 12.5- 

 15.1 (14.3), tarsus 14.9-18.4 (16.3) mm. 



Females (7 from Bocas del Toro and Costa Rica), wing 59.0-63.2 

 (61.2), tail 51.1-56.2 (53.9), culmen from base 13.8-15.8 (14.6, aver- 

 age of 6) , tarsus 15.4-16.8 (16.4) mm. 



Resident. Known in Panama only from western Bocas del Toro, 

 where it is uncommon. It was first collected there by Kennard, who 

 took a female at 300 m on the Boquete Trail, March 9, 1926 (Kennard 

 and Peters, Proc. Boston Soc. Nat. Hist., vol. 38, 1928, p. 463). Ben- 

 son collected a male and female at Almirante during May of 1927, and 

 4 immature females there on September 7 of that year, and H. von 

 Wedel took other specimens on the Boquete Trail and at Changuinola 

 in 1928 and 1929 (Peters, Bull. Mus. Comp. Zool., vol. 71, 1931, p. 

 342). North of Panama, axillaris is found along the Caribbean slope 

 to eastern Honduras.
