The three skins are very uniform inter sz. The back is bright grass-green, the 
bill large and somewhat blunt. An adult bird from Salinas, Beni, Eastern Bolivia, — 
in the Tring Musenm, has the under parts, including the throat, of a mach deeper 
olive-yellow, the ear-coverts brighter yellowish olive-green, and the bill decidedly 
longer. A series from the Roraima Mts. (British Guiana) and the upper Rio 
Negro (R. Icanna, Barcellos, Marabitanas)* differ from the preceding ones by their 
much doller, olive-green back, and much narrower, slenderer bill. An apparently 
immature female from Maipures (Orinoco R.), however, agrees perfectly with 
Mr. Hoffmanns’ examples. The type from Pebas (in the British Museum) should 
be re-examined in order to ascertain the exact application of the name gracilipes.

feet black, bill grey.”—Bill 12 mm. 
The adult bird (No. 482) agrees with Natterer’s type + in every respect, Both 
have a little white at the extreme base of some of the crest feathers. It differs, 
however, from the two specimens in the Vienna Museum and another adult g from 
Araguaya, Goyaz, in Mus. Berlepsch by its rather lighter, more greenish upper 
surface; this trifling variation is very likely individual. As correctly pointed 
out by Berlepsch & Leverkithn, &. /. spectabilis may be readily distinguished 
from E. f. flavogaster (= pagana auct.) by its much larger size and much stronger 
as well as longer bill. In seven specimens (five from Goyaz, one each from 
Calama and Barcellos, Rio Negro) the wing measures from 88 to 92, the tail 
from 79 to 85 mm. 
* « Myiopatis pusilla (?)” Pelzeln, Zur Orn. Bras. ii. 1868, p. 106 (part.). 
} Although Pelzeln (.c. p. 176) says that Natterer sent only a single male of this species, the Vienna 
Museum possesses two specimens from Natterer’s travels: an adult male taken at the city of Goyaz 
August 16, 1823, which is to be considered as the type,“and an adult male obtained at Barcellos, Rio 
Negro, August 31, 1831. The latter locality alone is mentioned in the systematic list of Pelzeln’s book 
(p. 107).
