Average of D. a. anabatina. D. a. saturata. 



4 males: wing, 98; tail, 84 mm. 3 males: wing, 99.6; tail, 83 mm. 



6 females: wing, 94; tail, 83 mm. 3 females: wing, 95.3; tail, 78 mm. 



This race of D. anabatina has thus far been found only in south- 

 western Costa Rica, from Pozo Azul southward, and extending down 

 the Pacific lowlands of Chiriqui as far as David (at least). It ranges 

 from sea-level up to about 1,500 feet, although it is more abundant 

 below 1,000 feet. It is an inhabitant of the heavy virgin forest, 

 creeping about on the tree-trunks continuously, and is very noisy 

 (probably only the males during the breeding season), uttering harsh 

 notes while running excitedly up a tree-trunk or hanging in one place 

 for several minutes. It is quite shy and it is sometimes difficult to get 

 within gunshot.

This species in Costa Rica is rarely found outside of the Nicoya 



peninsula and Guanacaste, where it is not abundant. There is only 



one authentic record of a specimen from any other region, that of Mr. 



Cherrie from Boruca. Neither Mr. Underwood nor myself found it in 



the Terraba Valley, so that it must be very rare there. Mr. Ridgway 



records a specimen as having been collected by J. Cooper at Navarro. 



I think there is every reason to doubt the correctness of the locality, 



and that the bird very probably came from San Mateo, where Cooper 



collected at different times, and where the bird might be rarely taken. 



At all events it is not a species of the Caribbean slope (Navarro is on
