312 PROCEEDINGS OF THE ACADEMY OF [1899. 



7. Troglodytes musculus puna (Berl. and Stolz.). 

 Distribution. — Highlands of Peru (type loc, Queta). 

 Larger than T. miisculus and color below not at all rufescent. 



Under tail coverts with very few spots. 



8. Troglodytes musculus albicans (Berl. and Tacz.). 

 Distribution. — Ecuador (type loc, Guaquil). 



Throat and middle of abdomen pure white, paler and grayer above 

 than mmculm and sides more rufescent. 



The last two and T. m. rex I have not seen, and am therefore in 

 much doubt as to the forms fi'om Peru, Ecuador and Bolivia. If 

 tecellata, puna and audax all occur in Peru, and are perfectly 

 separable, they must occupy very different geographic areas. 



The confusion of the tropical American Wrens in the published 

 works is very perplexing. The Biologia Centrali Americana 

 recognizes but two forms of the group here treated, i. e., T. 

 intermedins of Central America and T. furmis of South America! 

 The British Museum Catalogue is much better, but it is difficult to 

 imagine how Dr. Sharpe can unite the AVrens of Panama and 

 Bogota under T. striatulm and separate T. intermedius. The 

 Panama birds which I have seen are scarcely distinguishable from 

 T. intermedius, while the true striatulus from Bogota is very 

 different.
