160 Bangs Birds from Pueblo Viejo, Colombia. 



Tachyphonus rufus (Bodd.). 

 Four specimens, a male and three females. 



Helminthophila chrysoptera (Linn.) 

 One adult female, Mar. 20, 1898, winter resident. 



Basileuteius cinereicollia Scl. 

 One male. 



Thryothorus laetus sp. nov. 



Type (and only specimen), from Pueblo Viejo, Colombia. No. 5601, <j\ 

 coll. of E. A. and 0. Bangs. Collected Mar. 19, 1898, by W. W. Brown, 

 Jr. Altitude 8000 ft. 



Specific characters. Resembling in general style of coloration T. ratilus 

 Vieillot, but featbers of russet chest and white breast and upper abdomen 

 marked with black subterminally, giving a mottled appearance to the 

 under parts. 



Size.tf, wing, 59.6; tail, 49.4; exposed culmeu, 17. 



Remark*. At first glance the type and only specimen of T. laetus gives 

 one the impression of a spotted young, but a closer examination shows 

 that this is not so. The feet and bill are those of an adult and the plu 

 mage shows no signs of immaturity. 



Heiiicorhiiia leucophrys (Tsdmdi). 

 One adult male. 



Catharus aurantiirostris (Hartl.). 

 One adult male. 



Merula phaeopyga (Cabanis). 



Two males. These are not exactly the same as a specimen from British 

 Guiana (presumably taken near the type locality) in the National Museum 

 collection. Neither can they be referred to M. phxopyya .>y>o<//o/.T//w. 

 (Berl. and Stolz.) of central Peru, or to M. plixopyga mturata (Berl.) of 

 Bogota. It is very likely that they represent still another subspecies of 

 this wide-ranging and variable thrush.
