 ' The Osprey ' for June of the same year. This article contained data on 

 the longevity of 75 species, more than two-thirds of which exceeded 20 years, 

 and ten of which reached the age of 50 years or more. The oldest birds 

 mentioned in the list (omitting doubtful records) were a Sulphur-crested 

 Cockatoo and a Domestic Goose, each of which attained the age of SO years. 

 Only five North American species were included in Gurney's list, and appar- 

 ently data on the ages of our native birds are still very meager. — T. S.
