376 Annals of the Carnegie Museum. 



Sclater (Catalogue of the Birds in the British Museum, XIV, 1888, 

 93) diagnoses Hapalocercus mcloryplius as having the sides of the 

 head ashy brown, while in H. fulviceps these parts are fulvous. Evi- 

 dently misled by this, Mr. Bangs compared his Santa Marta specimens 

 of Hapalocercus with H. fulviceps. The type of H. meloryphus, 

 kindly loaned by Dr. Chapman, is in poor condition, being much faded 

 and worn, but the buffy sides of the head are clearly indicated 

 nevertheless. A specimen from the Rio Parana (No. 20,993, Collection 

 U. S. National Museum) is similar, as well as a series of no less than 

 fifteen specimens from Bolivia, northern Argentina, and Venezuela in 

 the collection of the Carnegie Museum. After very careful compari- 

 son of the entire series we can find no sufficient characters for divid- 

 ing it, and do not believe that paulus is worthy of recognition, even as 

 a race. The amount of rufescent edging on the wings and tail is a 

 variable feature, probably depending on age and season. 



According to von Berlepsch H. fulviceps is only subspecifically 

 separable from the present form. 



Mr. Ridgway suggests that Hapalocercus may belong to the Formi- 

 cariidae, but for the purposes of this paper we propose to retain it 

 provisionally in the Tyrannidse. 



Evidently this is a rare bird. The one taken at Don Diego was 

 shot in a tract of waste land, overgrown with shrubbery and weeds, 

 near the beach. The three taken at Pueblo Viejo were all secured in 

 the same place — a tract of second-growth and shrubbery on the out- 

 skirts of the village. Mr. Smith sent in two specimens from Don 

 Diego also. Mr. Brown claims to have taken it in the Sierra Nevada 

 at an altitude of 7,000 feet, but it may well be doubted if it regularly 

 goes so high up, being a bird of the Tropical Zone.
