the months of February, March, April and May, in moist places on 

 the banks of tlie river Rimac, near Lima. It li^es in flocks of eight 

 or ten couples. Its flight is very light. 



On the Hoazin {Opisthocomus cristatus). 



This bird is one of those whose position has always been embarrass- 

 ing to ornithologists. By Linnaeus and some other authors it was 

 placed amongst the Gallinaceous birds ; Temminck referred it to his 

 order Omnivori ; Vieillot to the Passerine birds ; whilst by Latreille 

 it was included in a small order intermediate between the Gallinaceous 

 and Passerine birds established by him for the reception of the 

 pigeons and some other birds. This according to the views of 

 M. Deville is its true position. 



The author here describes the anatomy of the bird and the struc- 

 ture of its beak and tongue (the latter organs being figured on pi. 9). 

 He states that it is entirely a phytophagous bird, the contents of its 

 stomach always consisting of the leaves of a tree known in Brazil 

 by the name of Aninga, in Guiana by that of Moueou Moucou (Arum 

 arborescens, Linn.). It lives in large flocks on the banks of rivers, 

 creeks and florid savannahs, where the above-mentioned tree grows 

 abundantly. Its note is a rough, grunting cry. It has an odour of 

 eastoreum, which its flesh also possesses, so that it is not used as food. 

 It nidificates in the lower parts of trees, forming its nest of branches 

 covered with some softer matter ; the female lays three or four eggs 

 of a dirty white colour with scattered red spots. This bird inhabits 

 Brazil, Peru, and Guiana. 



On the Caurale (HeUas phalenoides, Vieill.). 



M. Deville furnishes a few anatomical observations on this bird, 

 which he says lives in solitude on the banks of rivers and about 

 marshy ground, feeding upon insects, moUusca and small fishes. It 

 is excessively timid ; its note is a weak whistling, to an imitation of 

 which it will reply. It flies very hghtly, and rarely perches during 

 the day ; at night it perches on trees, where it also nidificates. The 

 female lays three or four oval eggs of a crimsoned yellow colour vnth 

 some spots of brick-red and violet-brown. It lives in Brazil, Peru, 

 and Cayenne. 



On the Savacou (Cancroma). 



Of this bird M. Deville also gives a few anatomical details. The 

 bird lives in pairs in the neighbourhood of water, and feeds upon in- 

 sects, moUusca and fishes. It is very fierce. The author thinks 

 that there must be several species of this genus.
