The three skins are very uniform inter .s.\ The back is bright grass-green, the 

 bill large and somewhat blunt. An adult bird from Salinas, Beni, Eastern Bolivia, 

 in the Tring Museum, has the under parts, including the throat, of a mucli 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 duller, olive-green back, and much narrower, slenderer bill. An ajiparently 

 immature female from Maipures (Orinoco R.), however, agrees perfectly with 

 Mr. Hoffmanns' examples. The type from Pebas (iu the British Museum) should 

 be re-examined in order to ascertain the exact application of the name gracilipes.

The adult bird (No. 4s2) agrees with Natterer's typef 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 iu the Vienna Museum and another adult <S 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 & Leverkiihn, Vi. /. spectabilis may be readily distinguished 

 from E. f. Jlavogaster { = 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.

t Although relzcin {I.e. p. 17ti) say.s that N':itt,erer .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 Ifi, 182.'?, which is to he considerefl as the type,*an(l an adult male obtained at Barcellos, Ilio 

 Negro, August 31, 1831. Tlie latter localitv alone is mentioned in the systematic list of Pelzeln's book 

 (p. 107).
