992 TROMPETER 
Messrs. Sclater and Salvin in their Nomenclalor (p. 141) admit 
6 species of Trumpet-birds—(1) the original Psophia crepitans of 
Guiana ; (2) P. napensis of eastern Ecuador (which is very likely 
the veritable “Oiseau trompette” of De la Condamine); (3) P. 
ochroptera from the right bank of the Rio Negro; (4) P. leucoptera 
from Peru and the right bank of the Upper Amazons; (5) P. 
viridis from the right bank of the Madeira; and (6) P. obscura, the 
distinctness of which is denied by Dr. Sharpe (Cat. B. Br. Mus. 
xxiii. p. 281), from the right bank of the Lower Amazons near 
Para. And they have remarked (Proc. Zool. Soc. 1867, p. 
PSOPHIA LEUCOPTERA. (After Mitchell.) 
592) on the curious fact that the range of the several species 
appears to be separated by rivers, a statement confirmed by Mr. 
Wallace (Geogr. Distr. Anim. ii. p. 358); and in connexion there- 
with it may be observed that these birds have short wings and 
seldom fly, but run, though with a peculiar gait, very quickly. <A 
seventh species, P. cantatriz, from Bolivia, has since been indicated 
by Prof. W. Blasius (Journ. f. Orn. 1884, pp. 203-210), who has 
given a monographic summary of the whole group worthy of 
attention. The chief distinctions between the species lie in colour 
and size, and it will be here enough to describe briefly the best 
known of them, P. crepitans. This is about the size of a large | 
barndoor Fowl; but its neck and legs are longer, so that it is a
