TERENURA. 213 
TERENURA.: 
Terenura, Cabanis & Heine, Mus. Hein. ii. p. 11 (1859) ; Sel. Cat. Birds Brit. Mus. xv. p. 257. 
Terenura is a peculiar genus of doubtful affinities, but remarkable for the bright 
colours of its members. These colours (black, bright yellow, chestnut, and olive), it is 
true, are all to be found in different species of Formicariide, but in Terenura alone are 
they associated in a single bird. 
Cabanis and Heine, who founded the genus, placed it between Ramphocenus and 
Eltipura (=Formicivora), and in this position it was left by Mr. Sclater. We cannot 
see that it has much in common with either of these forms, which, different as they are, 
both possess well-defined rictal bristles, not a trace of which can we see in Terenura. 
Mr. Sclater speaks of the presence in the latter genus of a slightly membranous nasal 
operculum such as is found in khamphocenus, but the specimens of Terenura callinota 
before us have open nostrils without any overhanging membrane. 
On the whole, and in the absence of any information as to the habits of any species of 
Lerenura, we are inclined to place the genus near Myrmotherula, notwithstanding the 
difference of coloration and the much longer tail. 
The bill is longer than that of Myrmotherula surinamensis, but is otherwise very 
similar. The wings are decidedly longer and Jess 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 lessrare birds. These 
are distributed over a wide area of Tropical America—one or two in South-eastern 
Brazil, one in Guiana, one in Eastern Ecuador, and 7. callinota, a western and north- 
western bird the range of which is given below.

This pretty species was described and figured in 1855 by Mr. Sclater from a specimen 
(a trade skin from Bogota) in the British Museum!. We have since seen other 
examples from the same country. Buckley obtained a bird of the same species near 
Nanegal in Ecuador, and one was sent us from the State of Panama by our collector 
Arcé after the second list of his birds, published in 1870, was issued. All these birds
