From tlie Maccaw division we now proceed to 
tlie subfamily Psittacina, containing a numerous as- 
semblage of species, distinguished by their compa- 
ratively stout and generally even tail. The largei 
species of this division answer to M. Kohl's fourth 
section Psittacus, and are usually known among us by 
the special title of Parrots. These by Wagler, in his 
Monographia Psittacorum, have since been divided 
into several groups, and constitute his genera Eclcc- 
tus, Psiltacodis, Psittacus, and Pionus. In this 
subfamily, the bill, though very powerful and strong, 
is more elongated than in the Maccaws and Cocka- 
toos, the head is large, and the face, with some few 
exceptions, covered with feathers. The tail is short, 
with the end even, or else slightly rounded ; and the 
wings are generally ample and long. It forms the 
typical group of the family, and is nearly allied to 
the Cockatoos, or subfamily Plyctolopliina, by some 
interesting forms, among which may be mention- 
ed Nestor hypnpolius, Wagler, and by some of its 
smaller members, to the short-tailed diminutive spe- 
cies of the Lory division ; while their connection 
with the Macrocercince is supported by the forms 
previously adverted to. Tlie species are found dis- 
tributed in Asia, Africa, and America, and are all 
inhabitants of the torrid zone. Many are gregariouB, 
except during the period of incubation. They breed
