Obs.— The Rev. Churchill Babington in “Flora of New Zealand," p 
310, places under the head of Myriangium inconspicuum a lichen which Dr. 
Nylander has since shown to be an Arthonia allied to Arth. lurida and has 
named Arth. conspicua (see Nylander's Lich. Novo-Granatense, note, p. 67, 
1st ed.). Babington in his remarks does not seem to be aware that there 
exists in New Zealand a true Myriangium, viz., Myr. duriei, a perfectly 
developed species of that very curious genus.
