The Cockbuni Island plant, referred (in Lond. Journ. Bot.) to this, we have elsewhere described as Lecanora Babingtoni.

I have little hesitation in considering this plant to be that described by Tries ; though I know the latter from description alone. It approaches Schserer's L. atro-alba (n. 178); but the apothecia do not appear to rise from the thallus. C. Babinyton.

At first sight this resembles Lecanora subfusca, (or rather the var. orostltea,) but the hypothallus is quite black. I feci no doubt of its being the L. glacialis, which is compared with the above-mentioned species, both by Fries and Sehserer. The only difference I can detect between the European and Antarctic specimens, lies in the apothecia of the former being dusky within, and not white.

I am hardly satisfied with the determination of the Hermite Island specimens : they are certainly allied to the L. sabuletorum and also to L. arctica. They further resemble Bialora verualis, var. sangtdneo-atra, Fries; but this L. sabuletorum is scarcely a Biatora, and may be an undescribed species of Lecidea. C. Babhtgton.
