GALLING, 229 



even descend a considerable way down the tarsus. These 

 may be considered as the genuine terrestrial birds ; al- 

 though a few species may be found among them, as the 

 king's fisher and water crow, which, in their manners, ap- 

 proach the waders. 



Three toes directed anteriorly. 



A. Nostrils hid under an arched covering. The bill is 

 vaulted ; the toes have serrated edges, and the feathers of 

 the wings are short. The stomach is a strong gizzard. The 

 food consists chiefly of vegetables, occasionally mixed with 

 insects. 



a. Bill arched from the base. Eggs numerous. This 

 group includes the GALLING of LIN. The characters of 

 the species, as connected with systematical arrangement, 

 have been very imperfectly explored. The males, in gene- 

 ral, have spurs. 



1.] First and second toe united at the base. 



(A.) Hind-toe fully developed *. 



(a.) Front or crown of the head appendiculated. 



Appendix consisting 1 of feathers. The genera of ;this 

 group have a crest of feathers, which they can elevate and 

 depress at pleasure. 



Tail coverts remarkably produced. 



1. PAVO. Peacock. The size, the motions^ and the colour- 

 ing of the tail, distinguish this genus from all others. There 

 are two species, the P. cristatus, or common peacock, and 

 the bicalcaratuS) or double spurred kind, which TEMMINCK 

 has placed in a separate genus, termed Polyplectrum. 



* * It is probably among the Gallinaceous birds, and in this section, where 

 the doubtful genus Didus of LIN. will be placed, when the species shall have 

 been more carefully examined.
