100 Bcmgs — On Some Birds from. Santa Maria, Colombia. 



Premnoplex brunnescens (Scl.). 



Two females, one fron'i San IMiguel, the other from Cliirua. 



Dendiocincla olivacea anguina Bangs. 



Three specimens, one each from Palomina, Chirna, and La Concepcion. 

 All are similar to the type, the onl}' specimen ]\Ir. Brown had previously 

 taken. 



Picolaptes laciymiger (Des Murs.). 



One female from La Concepcion. 



Diymophila caudata (Scl.). 



Twenty-five specimens, yonng and adult of both sexes, from Chirua, 

 La Concepcion, San Francisco, Santa Cruz, San Antonio, and San Miguel. 

 I am now inclined to consider the Santa Martabird true D. caudatn (Scl.), 

 although when I recorded the first two, taken by Mr. Brown at Palo- 

 mina,* I thought that they were not that species. The tails are about tlie 

 same throughout the series and do not difier, to any extent, with age or 

 sex. The rectricesare dark brown (l)etween raw umber and bister), with 

 subapical black bands and white tips. The only specimen from ' Bogota ' 

 in the National Museum has a precisely similar tail. Sclater's descrip- 

 tion reads : ' Tail of ten feathers, very long, much graduated, black, with 

 white ends.' This was probably a mistake. 



Conopophaga bio-wni f sp. nov. 



I'lve specimens, both sexes, from Chirua.
