58. Hutton on Migratory Birds in New Zealand. 
[Our Migratory Birds. By Capt. F. W. Hutton, F.H.S. Trans. New 
Zeal. Inst. 1900, p. 251.] 
This is an interesting paper which we commend to the 
notice of all who wish to study the difficult problems of 
Migration. The only regular summer visitors to New 
Zealand, for the purpose of breeding there^ are the two 
parasitic Cuckoos Eudynamis taitensis and Chrysococcyx 
lucidus. But numerous Waders and other birds appear 
there more or less sporadically, besides a number of accidental 
visitors from Australia and other adjacent lands.

Acanthopneuste puella is based on several specimens received 
by the National Hungarian Museum from the vicinity of 
Yladivostockj Eastern Siberia. It is nearly allied to Phyllo- 
scopus coronatus of Japan (Cat. B. v. p. 48), but has no 
light middle stripe on the head, and shews other points of 
difference.

Before the appearance of the present paper Dr. Mitchell 
had, in a communication to the Zoological Society of London, 
directed attention to the importance of the intestinal tract 
as a basis of bird-classification. 
The very large series of differences in the size of the various 
loops and folds of this tract lend themselves to a regular 
arrangement of birds in correspondence therewith, and, what 
is more important^ permit of a reasonable guess at the more
