35. Oktalis RUFicAUDA, Jard. 

 E/io Apure. An adult bird. 



Long. al. 243j caud, 270^ culm. 30, tars. 73 millim. 



Agrees with a specimen from Puerto Cabcllo (Mus. H. v. B.), 

 but is of rather larger size, with much larger bill, and gener- 

 ally lighter colours, crissum lighter rufous-brown. I believe 

 the Puerto-Cabello bird is not quite adult. 



36. Opisthocomus chistatus (Lath.). 

 Angostura. An adult. 



Long. al. 345, caud. 322, culm. 28, tars, 58 millim. 



Agrees with a specimen from Yquitos, Upper Amazons, 

 but wings, tail, aud crest longer. 



So far as I know, this bird has not hitherto been recorded 

 from Venezuela. 



37. Aramides cayennensis (Gmel.). 



Angostura. A somewhat small and pale-coloured speci- 

 men, but otherwise agreeing with individuals from British 

 Guiana and Panama.

 while an individual from Santa Catharina is of much larger 

 size and paler in coloration.
