Thanks to the kindne.ss of my friend l)r. von Loriiiz, of Vienna, 1 was enaliled 

 to examine Pelzeln's specimens, and I found them absolutely identical witli tiie 

 type of//, hemih'uca in the British Museum. Perhaps they have a slightly longer 

 bill, but, as will be seen from the measurements given above, the difference is hardly 

 apparent. Mr. Allen's careful description leaves also no doubt that his iL/rmochanes 

 hi/jjoleucus is nothing else but the species in ijuestion. 



It need not be added that this bird has nothing to do with Terenura or with 

 I'ljrujlena, but it agrees structurally with some species of the genus Ilijijocnemis, 

 except that the bill is rather flatter and rather more compressed towards the tip. 

 However, //. melanopoijon and //. macuUcauda are intermediate in this respect, and 

 therefore I do not venture to sejMrate //. hemilcuca generically from Ili/pociicmin. 



In the Cat. of Birds sv. p. 291, Mr. Sclater gives the description of tlie ? of 

 //. hcmilciica, but there must be some mistake here, as neither Bartlett nor any 

 other naturalist collected specimens of this sex. 



The British Museum possesses only the single S ad. upon wliich Sclater and 

 Salvin based their original description. 



The range of //. hemileuca, thus far known, is as follows : 



E. Peru : Lower Ucayali (Bartlett); y.E. Bolivia: Reyes (Rusby); -X. Brazil : 

 Borba (Natterer).
