Club, printed in the May 1920 number of the journal, 
deals with colours of birds in relation to their habits. 
He suggests that the conspicuous white rump and wing- 
patches of many birds are useful as a signal of alarm and 
danger. 
A new bird to the Irish list is the Carolina Crake or 
Sora Hail (Por2ana Carolina), an example of which struck 
the lantern of the lighthouse at Slyne Head, co. Galway, 
on 11 April, 1920. and is recorded by Prof. C. J. Patten in
