several more specimens, one of which is mounted in the Canterbury 
Museum, and three of which I have in my own collection. All of these 
birds are in their winter plumage. 
There is not a great deal of difference between the marsh and pectoral 
sandpipers, and what there is would be almost impossible of detection in 
the field. 
The pectoral sandpiper breeds in Arctic America and migrates south 
through the American continent in the winter even so far as Patagonia 
` and the Falkland Islands. It also occurs in eastern Asia, and it is doubt- 
less from there that these birds have come to New Zealand, joining up with 
the flocks of knots and godwits.

The curlew sandpiper may, I consider, be put down as one of our 
egular migrants. Two specimens whic shot on Lake Ellesmere on 
‘the 5th April, 1903, were the first of this species to be recorded for New 
Zealand, but since then I have seen it on many occasions ha 
secured a number of specimens. It is usually to be found associating 
with the banded dottrel. On one occasion I saw between twenty an 
thirty curlew sandpipers, which were in a large company of dottrel. 
When disturbed both species rose and flew around together, and when 
they settled again the curlew sandpipers all settled together, and slightly 
segregated from the dottrel. Most of the specimens I have o tained have 
ad some signs of summer plumage, though none has had the full breeding- 
ress. 
Its nest had not been found until July, 1897, when the bird was 
discovered breeding in the Yenisei Valley. 
In conclusion, I wish to express my thanks for the very valuable 
assistance I have received, in preparing this paper, from Mr. Gilbert Archey, 
Canterbury Museum. He did all the nomenclature, and helped me with 
the identifications.
