"On the whole, and in the absence of any information as to the 

 habits of any species of Terenura, we are inchned to phxce the genvis 

 near Myrmoiherula, notwithstanding the difference of coloration and 

 the much longer tail. 



"The bill is longer than that of Myrmoiherula surinamensis, but is 

 otherwise very similar. The wings are decidedly longer and less 

 rounded. The tarsi are covered behind with large scutella, the 

 sutures of which are, however, rather indefinite. 



"Four or five species constitute the genus Terenura, all more or less 

 rare birds. These are distributed over a wide area of Tropical 

 America — one or two in Southeastern Brazil, one in Guiana, one in 

 Eastern Ecuador, and T. callinota, a western and northwestern bird 

 the range of which is given below"" [Veragua to Peru].
