helpless, and leed from the mouths of their parents, are 

 called AUrices. The common Eobin is a good illustration 

 of this group. Other birds, like the hens and ducks, have^ 

 young which are able to run about and take care of them- 

 selves, in part at least, as soon as hatched. These are called 

 Precoces. Each of these sub classes is to be divided into- 

 several orders, hut Bonaparte himself has made various 

 alterations in the serial arrangement of the orders and sub- 

 orders in his pu Wished papers. If wc place the singing' 

 birds highest, as I have pioposed, instead of the parrots, the 

 following arrangement, thougli somewhat different from^ 

 either of those of Bonaparte, seems to me the most natural. 



Of the AUrices, the first order will be the Passeres, inclu- 

 ding the singing birds or Oscines, as well as most of the 

 other small perching birds ; second the Scansores including' 

 tlie parrots ; third the Accipitres or birds of prey ; fourth 

 the Cohimbcv or doves and pigeons, and perhaps, also, the; 

 Dodo, which is very little known, and forms, in one of the' 

 arrangements of Bonaparte, a separate order, called Inepti ; 

 fifth, the Herodiones. including the herons, cranes and the 

 like ; and sixth the Gavirc, with two sub-orders embracing 

 the gulls, albatross, pelicans, cormorants, &c. 



In the second sub-class or Precoces, there are four orders f 

 first, the Gallincc, including the hens, pheasants, &c. ; sec- 

 ond, the Struthiones, embracing the ostrich and other simi- 

 lar birds ; third, the Grallcc, containing the plovers, sand- 

 pipers, and the like ; fourth, the Anseres, including the- 

 two sub-orders Lamellirostres, or ducks, geese, etc., and 

 Brachypteri or auks aad divers. The penguins in the 

 latest arrangement of Bonaparte form a distinct order, the 

 lowest of the Altrices, but previously they had been placed 

 as a sub-order, Ptilopteri, under the Anseres. The Flamin-
