80 PLANTS FROM NEW CALEDONIA. 
deformation occurs in Pannaria perfossa Stirton, a New Zealand plant, 
but the apothecia of the latter have crenulate margins and smaller spores, 
and the structure of the thallus is different. 
The specific name Montaguei commemmorates the brilliant young zoologist, 
Paul Montague, with whom Mr. Compton was associated in the expedition to 
New Caledonia. Mr. Montague joined the army on his return to England 
and served in the R.F.C. He lost his life in an air-fight in Salonika.
