Huallaga. This is the greatest depredator in the country ; it visits 

 the plantations in large flocks, in early morning and evening, eating 

 and destroying the ripe bananas and other fruit of the planter. It is 

 the commonest of all the genus, and breeds in large colonies." — E. B. 



7. Ostinops atrovirens (Lafr. & D'Orb.) ; Scl. & Salv. P. Z. S. 

 1866, p. 182.

8. Cassicus persicus (Linn.) ; Scl. Cat. A. B. p. 128. 



" Upper and Lower Ucayali, Nauta, Santa Cruz. This beautiful 

 species breeds in small numbers in the trees on the banks of lakes 

 and streams, near town, sometimes low down, and at others high up in 

 the tall spiny palms. " The nests are generally matted together ; and I 

 found that the whole of this group of birds select a tree with a large 

 nest of Wasps or of White Ants in it, whether for protection or for 

 food I am unable to determine. I watched them for hours, and 

 could never discover them interfering with the nests of either of these 

 insects. I obtained the eggs and nest of this species with great 

 difficulty and with the chance of being stung to death. 



"The nest is about 1| foot long, with a pocket at the upper end. 

 The eggs four in number, of a pale greenish white ground-colour, 

 streaked and spotted at the large end with brown and grey." — E. B. 



9. Cassicus h^emorrhous (Linn.); Scl. Cat. A. B. p. 129.

 Chamicuros, the only locality in which I observed it. I found it in 

 company with Ocyalus latirostris." — E. B.
