arundinacea), and occasionally remains of old wrecks. In 
these localities the nests were placed very thickly, and young 
birds were in multitudes. Most of the nests were just depressions 
in the sand, but others were lined with anything that came handy, 
as broken shells, grass, seaweed, egg-cases of squid, and other 
materials. 
All the species bred together ; but the Common Tern was 
by far the most abundant, while the Arctic came next, and the 
Roseate in much smaller numbers. Owing to the presence of 
foxes on the island, the birds are much disturbed on their breed- 
ing-grounds, and this year many nests were placed on the sand- 
hills near the stations, where foxes dare not come. Onthe sand- 
hills where grass was plentiful the nests were still mere depres- 
sions in the sand, and hardly any had even a slight lining of 
grass. 
MUSEUM SPECIMENS. 
We have specimens taken at Indian Head and Crane Lake, 
Assa. Of eggswe have 27specimens. Fourof these are from an 
island in Lake Winnipeg, taken by Mr. J. B. Tyrrell ; and twenty-

71. Arctic Tern. 
Sterna pavadis@a BRUNN. 1764. 
This Tern, although an arctic bird, seems to be little known in 
Greenland but breeds in Ungava Bay and southward to Nova 
Scotia. (Downs.) Brewster reports it breeding abundantly on the 
Magdalens, and in June 1897 the Rev. C.J. Young found it there, 
and it has been found breeding in other parts of the Gulf of St. 
Lawrence. Chamberlain says it is rare in New Brunswick and 
only asa straggler. MclIlwraith says it is of rare occurence in 
Ontario, and all our researches in the western territories never 
revealed this bird east of the Columbia River. Numbers were 
seen on Upper Arrow Lake, Columbia River, B.C., June 5th, 1890, 
but they went north a few days later. 
Breeds as extensively as the Common Tern and extends as far 
north. (MWacfarlane.) This species breeds very abundantly on the 
shores of Melville Peninsula and on the islands and beaches 
of the Arctic Sea. (Richardson.) On the sandy islands east of
