BIRDS OF NORTHERN VENEZUELA — WETMORE 239 



THRYOPHILUS RUFALBUS CUMANENSIS (Cabanis) 



Troglodytes cumanensis "Licht." Cabanis, Journ. fiir Orn., 1860, p. 408 (Cartagena, 

 Colombia) . 



On October 24 in a deep, wooded ravine above the Rio Cumboto, 

 near Ocumare de la Costa, I saw two of these wrens working about 

 near the ground. They scolded in wren fashion and then disappeared, 

 but by careful watching I took one, an immature female. This bird 

 has the duller dorsal coloration of these wrens in northern Venezuela. 



WMle Hellmayr " has adopted van Rossem's suggestion ^* that 

 Pheugopedius and Thryophilus be merged, as well as possibly Thryo- 

 thorus, I am not prepared to accept this until the whole matter has 

 been more carefully studied. 



THRYOPHILUS LEUCOTIS VENEZUELANUS (Cabanis) 



Thryothorus venezuelanus Cabanis, Museum Heineanum, vol. 1, 1861, p. 78 

 (Venezuela) . 



At Ocumare de la Costa on October 30 I secured two of these wrens 

 after much patient labor in low scrub where they inhabited the densest 

 cover. One is an immature female that has just completed the molt 

 into the first adult plumage. This specimen measures as follows: 

 Wing 59.5, tail 40.8, culmen from base 18.3, tarsus 19.7 mm. The 

 other, an adult female, is in full molt on the body and head. 



THRYOPHILUS LEUCOTIS HYPOLEUCUS Berlepsch and Hartert 



Thryophilus albipectus hypoleucus Berlepsch and Hakteet, Bull. Brit. Orn. 

 Club, vol. 12, Oct. 30, 1901, p. 12 (Altagracia, Rio Orinoco, Venezuela). 



On November 20 I secured an adult male at El Sombrero in a tangle 

 of vines and branches in low woods near the Rio Guarico. This speci- 

 men is much paler than the two from Ocumare de la Costa, being 

 nearly white on the throat and breast, with the color of the flanks 

 and posterior underparts paler, and is grayer above, except for the 

 tail, which is lighter, brighter brown. It measures as follows: Wing 

 62.1, tail 43.8, culmen from base 18.5, tarsus 21.3 mm. It agrees 

 with skins from Soledad and Ciudad Bolivar and marks a considerable 

 extension in the range of this form. 



PHEUGOPEDIUS MYSTACALIS RUFICAUDATUS (Berlepsch) 



Thryothorus ruficaudatus Beelepsch, Ibis, 1883, p. 491 (Puerto Cabello, Vene- 

 zuela) . 



The only specimen of this rare bird secured was shot in heavy 

 forest at an elevation of 3,900 feet above Rancho Grande, where it 

 was working through branches and creepers not far above the ground
