Ornithion, aud sj'nonymised it with M. obsokta Temm. On examiuiiig a very large 

 series of skins from varions localities iu Soutliera and Eastern Brazil, I find, 

 however, that those from Espiritn Santo, Bahia, Gojaz, and Mattogrosso differ 

 from trne 0. o. obsoletum, of southern Minas Geraes (Oongonhas), S. Paulo and 

 Parana in decidedly smaller size and slightly paler coloration, especially of the 

 upper i)arts. Two t()potyi)ical specimens from the llio Espiritn Santo, for the 

 loan of which I am greatly indebted to Professor H. v. Ihering, of S. Paulo, fit 

 admirably several freshly moulted birds from Bahia; hence cinerascfns becomes 

 the proper subspecific appellation of the pale, short-winged northern race. 



It may be mentioned that the original specimen from Congonhas, upon 

 which Burmeister based the description of his Elaenea miirina,* and which was 

 kindly submitted to my inspection by Professor Taschenberg, of the Halle Museum, 

 is referable to typical 0. o. obsoletum, agreeing in every way with skins from 

 S. Paulo and Parana. This had already been stated by Count Berlepsch.t The 

 range of the two forms is accordingly as follows :
