As we have often heard said, the establishment of a Zoological 
Garden is a very fair test of the progress of civilization in 
every country. We thank Capt. Flower for the trouble he 
has taken in preparing this useful list. We have already 
noticed his report on the Zoological Gardens in Europe 
which he himself visited in 1907 (see 4 The Ibis/ 1908, 
p. 619). 
6. Fulton on the Disappearance of New Zealand Birds , 
[The Disappearance of New Zealand Birds. By Dr. Fulton. Trans. 
New Zealand Inst. xl. p. 485.] 
“ Owing to change in environment, alterations in food- 
supply, and disturbance of the balance of Nature by 
ridiculous importations of birds and animals,” Dr. Fulton 
tells us, “ our beautiful feathered friends are fast going to 
the wall.” He discusses the different groups of Land-birds 
of New Zealand, and gives ample proofs of this melancholy 
fact. The Birds of Prey “are now rarely seen,” the Tui 
is “ fast disappearing,” the Thrush is “very rare,” the Native 
Quail is “ absolutely extinct ”—such are the sad stories put 
before us. The same sort of process is, no doubt, going on 
in all civilized lands, but in New Zealand it is progressing 
more rapidly.

The third part of this important Monograph continues 
the good work on the system described in our notices of 
the first and second parts (see 4 Ibis/ 1907, p. 515, and 1908, 
pp. 367, 527). The present part is mainly devoted to the 
widely spread genus (Estrelata , of which 23 species are 
recognized, and all but two are figured, with “ more to 
come.” They are far wanderers, as their name implies, and
