been taken at 7,000 feet, although this figure is undoubtedly a mistake. 

 Mr. Smith sent in a single specimen from Onaca, shot January 7, 1899. 

 The writer took a fine pair at Don Diego on January 31, 1914. These 

 were the only ones seen or heard, and were found in a ravine in the 

 heavy forest a short distance up in the hills abeve the coastal plain. 

 The four specimens just enumerated are the only ones known. Like 

 all the forms of this genus, it is very rare and very hard to find, on 

 account of its shyness and retiring habits. 



Since the above was written the species has been noted not uncom- 

 monly in the heavy forest of the dark ravines on the north and east 

 slopes of the San Lorenzo, from 2,000 up to 4,000 feet. It has a very 

 characteristic song of several clear liquid notes, which have such a 

 pronounced ventriloquistic quality that the bird is very difficult to lo- 

 cate by its song. The bird invariably keeps on or very near the 

 ground, while the song appears to come from up in the trees. 



The most recent record is that of several individuals heard singing 

 at Loma Larga, on the eastern flank of the Sierra Nevada, in July, 

 1920. 



376. Thryophilus albipectus venezuelanus (Cabanis). 



Thryophilus albipectus bogotensis (not of Hellmayr) Oberholser, Proc. U. 

 S. Nat. Mus., XXV, 1902, 66 (Don Diego; descr. ; crit.). 



Twenty-six specimens : Buritaca, Don Diego, Dibulla, Arroya de 

 Arenas, and Fonseca. 



The Thryophilus albipectus group has always given a great deal of 

 trouble to ornithologists, several authors having struggled with the 

 problem, with more or less success. We have to do here only with the 

 Santa Marta bird, misidentified, as it now appears, with T. albipectus 

 bogotensis Hellmayr by Dr. Oberholser some years ago, after examin- 

 ing a specimen from Don Diego (No. 9,365, Collection Carnegie 

 Museum). Fortunately we have for comparison a good series from 

 various points on the north coast of Veftezuela, whence came the type of 

 Thryothorus venezuelanus Cabanis. These are quite indistinguishable 

 from the Santa Marta series, and with them are barely separable from 

 typical Cayenne birds, differing only in being a shade more brightly 

 rufescent above. The ashy gray sides of the neck, to which Mr. Hell- 

 n;ayr refers (Novitates Zoologies, XIV, 1907, 3), are not a diagnostic 

 character, being precisely the same as in the Cayenne examples. T.
