bill ; lastly, three or four others from Patagonia and the Andes, 

 which could not properly be placed in any of the genera already 

 constituted. 



The pigeon tribe will likewise be increased by the addition 

 of many new species. 



The gallinaceous tribe will receive many important addi-; 

 tions ; among others, the genera tinamou and tinochorus, esta- 

 blished by M. Eschscholtz on a species of bird sent by our tra*; 

 veller to the museum ; besides two new species with tridactylated 

 feet, one from Patagonia, the other from the higher regions of 

 the Andes, and which seem to admit of being formed into two 

 genera, which have accordingly been established by M. I. 

 Geoffroy, under the name of Eudromia. Unfortunately, M. 

 d'Orbigny, not being aware of the importance of possessing the 

 skeleton, or, at least, the sternal apparatus of those birds inter- 

 mediate between the pigeons and the gallinaceae, has preserved 

 nothing but their skins. This has likewise been the case with 

 the hoazins and penelopes that he met with, so that their place 

 in the series may yet be regarded as doubtful. 



The cursores appear to have furnished a less abundant har- 

 vest. We may mention, however, a complete series at all ages 

 of nandou, a species of ostrich with three toes, illustrated by a 

 beautiful skeleton ; a fine example of the humphed kamichi ; 

 as well as a new species of agami, of phenicoptera or flamingo, 

 of foulque, and of phalarope. 



Of the palmipedes, M. d'Orbigny has collected in his travels 

 twenty-five species of the extensive genus Anas L. the greater 

 part of which are unknown to naturalists. 



In general, the ornithological aspect of the" unexplored coun- 

 tries of South America, presents nothing very peculiar. Only 

 one or two species have been remarked which could be regarded 

 as identical with the birds of Europe. It may also be noticed, 

 that M. d'Obigny figured and coloured, with great care, while 

 the specimens were yet fresh, the eyes and beaks of all the birds 

 that he collected, as well as their eggs, and that he neglected no 

 opportunity of observing their habits and periodical migrations. 

 Among other facts, he remarked that the Ani is not the only 

 bird which makes a nest common to many females, as he found 

 a species of cuckoo, and a parakeet, which follow the same
