18 DIVISION I. VERTEBRAL ANIMALS.—CLASS II. AVES. 
Again, speaking of the Crimson-fronted Parakeet, Coolich of the natives 
(Trichoglossus concinnus) Mr. Calez states that it may be observed in 
large flocks sucking the Eucalypti flowers. He adds, that like the Blue- 
Mountain Parrot, it is subject to fits, which generally prove fatal ; that it is 
seldom kept alive, and that its breath, or some part above its head, emits a 
very sweet odor. The natives told him that this species breeds in the hollow 
boughs of trees, scraping out the decayed mould, and making its nest of it. 
The eges, he informs us, are green, without spots, and the number of young ° 
two. Of the Small Parakeets (Jarryang of the natives) (Tiéehoglossus 
pusillus), he observes that this, like the Coolich, is seen in very large 
flocks in the Hucalyptt trees when in bloom. “The natives,” says he, 
“now and then bring in the young ones, but they seldom live long. I had 
three young ones for some time, which used to huddle together, and give out 
avery pleasing note. They all died strongly convulsed, and nearly at the 
same time the limbs were as stiff the moment life was extinct as if the 
body had become cold. The natives tell me that it builds in the hollow 
limbs of trees, making no other nest than of the decayed wood. The eggs 
are white and without spot.” 
In the Cockatoos the bill is strong, short, broad, with the upper mandible 
much curved; the head is ornamented with a folding crest; base of the 
under mandible frequently concealed by feathers. Wings long; tail even. 
Locality, Australia and the Indian Islands. These birds inhabit the woods, 
feeding on fruit, and breeding in hollow trees: their ery is harsh, loud,-and 
disagreeable, but they are readily tamed, and though not celebrated for their 
powers of imitation, are engaging from their gentleness and affectionate dis- 
position. Their plumage is very powdery. They live long in captivity. 
An authenticated instance is on record of a great Sulphur-crested Cockatoo 
which attained the age of one hundred and twenty years. Mr. Gould, who, 
in his “ Birds of Australia,” has given a magnificent figure of the Cacatua 
galerita of Vieillot, observes, that if we regard the White Cockatoo of Van 
Diemen’s Land and that of New Guinea as mere varieties of each other, 
this species has a more extensive range than most other birds. It is an in- 
habitant of all the Australian colonies, both on the southern and northern 
coasts, but has not yet been seen on the western. “On a close examination 
of the specimens from the three countries above mentioned, a decided differ- 
ence is observable in the structure of the bill, or rather, perhaps, a modifica- 
tion of the organ for the peculiar kind of food afforded by the respective 
countries. The Van Diemen’s Land bird is the largest in every respect, and 
has the bill, particularly the upper mandible, less abruptly curved ; the bill 
of the New Guinea bird is much rounder, and is, in faet, fitted to perform a 
totally different office from that of the White Cockatoo of Van Diemen’s
