" L. supra aureo-Yiridis, subtus sericeo albns, gulte et colli lateri- 

 bus maculis paryis, lateribus pectoris hypochondriisque aureo 

 viridibus ; subcaiidalibus albis, minoribus macula centrali viridi 

 aurea ; rectricibus acuminatis glauco viridibus unicoloribus." (Ber- 

 lepsclt, in Orn. Per.) 



This bird appears to differ from its congeners by the uniform 

 coloration of its tail. Count Eerlepsch's specimen was obtained by 

 Whitely at Huiro in Peru, and others from the same source were 

 doubtless referred to L. cMonor/aster by Sclater and Salvin in their 

 list of Whitely's birds from that locality. One of these specimens, 

 through Mr. Whitely's kindness, I have now before me, and it agrees 

 with Count Eerlepsch's description. The Peruvian skin sent to 

 Gould by Warszewiez I believe to be the female of this species. It 

 is a discoloured specimen. The tail is pale at the base, the lateral 

 rectrices have whitish tips and a wide indefinite subterminal dark 

 band.
