The Xenicopsis collected in the Santa Marta region by Messrs. 

 Brown and Smith was at first presumed to be X. striatic ollis, the form 

 inhabiting central Colombia, until Mr. Bangs pointed out its distinc- 

 tive characters in 1902. There is little difference between the two 

 forms in the color of the upper parts, but anxius is markedly yellower 

 below, the throat and superciliaries being mustard yellow. It is clearly 

 only subspecifically distinct from striaticollis, and according to Dr. 

 Chapman and others the latter is similarly related to the Peruvian 

 form, montanus. 



A species which is found in the heavy Subtropical Zone forest be- 

 tween about 5,000 and 8,000 feet in the San Lorenzo, dropping down 

 as low as 3,000 feet in the Sierra Nevada. It is an active, noisy bird, 

 continually scrambling and hopping about among the branches of the 

 trees, but unlike the stiff-tailed species doing little real climbing. It 

 is fond of rummaging about in the bromelias for insects.
