108 Bangs On Some Bir<lsJ'r<nn S<uit<i Marta, Colombia. 



Measurements. 



Remarks. This new form of the white-bellied thrush is in all proba 

 bility not confined to the Sierra Nevada de Santa Marta. but is a large 

 northern subspecies. True M. albiventris of Brazil is a much smaller bird, 

 besides differing somewhat in the color of the head. The young bird, in 

 nestling plumage, from Palomina, taken May 21, 1898, that I recorded as 

 probably the young of Merula incompta* proves on examination to be 

 the young of M. albiventris fusa. 



Merula phaeopyga minuscula Bangs. 



Ten specimens, nine males and one female, from La Concepcion and 

 Chirua. All these agree closely with the original specimens. 



Platycichla flavipes carbonaria (Licht.). 



Seven specimens, both sexes, from Chirua, La Concepcion, and San 

 Miguel. 



Catharus fuscater (Lafr.). 



One adult male from Chirua, Feb. 5, 1899. 'Iris white; orbital ring 

 reddish orange ; bill reddish orange, but apex of culmen dusky ; tarsus 

 light orange.' f
