Campbell's Islands] Dr. Montague distinguishes this from the 8. carpoloma, Delise, by its having the apothecia on the surface, as well as on the margins of the frond, and by its different under surface. Our specimens are in a rather imperfect state.

The S. variabilis, Ach., is also enumerated by Montague as a native of Lord Auckland's group.

8. PARHELIA, Ach.

1. Parhelia rubig'mosa, Ach., Syn. Lick. p. 202. Lichen affinis, Engl. Bot. t. 983.

Hab. Lord Auckland's group and Campbell's Island ; on the bark of living trees, also on the ground on the lulls.

A most variable plant and a very abundant one in New Zealand and Tasmania ; on the hills the thallus is reduced to a few imbricating scales, as in Squamaria, and the apothecia are strangely contorted and closed, having the border closely indexed; in this state we are inclined to suspect that it passes into the Lecanora Hypnorum of these islands.

2. Parhelia sphinctrina, Mont, in Toy. au Pole Sucl, Bot. Crypt. 1. 15. f. 3.

Hab. Lord Auckland's group ; on the bark of trees.

This, judging from our copious suites of Tasmanian and New Holland specimens, is hardly distinct from P. rubiffinosa. Montagne's figure of it is excellent.

9. LECANORA, Ach,

1. Lecanora Hypnorum, Ach., Syu. Lich. p. 193.

Hab. Campbell's Island ; upon tufts of Andreaa and other mosses. The upright mode of growth and slender lacinias of the thallus, distinguish the present from its allies ; the specimens are of a dusky yellow colour.

2. Lecanora versicolor, Hook. fil. et Tayl.;" substrato adnato tenui atro, thalli squamuhs subrotundis planis crenulatis albidis demum flavis confertis bevibus, apotheciis majusculis sessihbus coneavis, disco nigro-pruinoso, margine integerrimo subincurvo.

Hab. Lord Auckland's group ; on bark.

Caspites 1 unc. latae, nigro-limitatae, substrato continuae, fuscae v. pallide virescentes. Apothecia squamis majors, disco nigro-pruinoso, margine thallode crassiusculo.

Allied to the L. varia, but marked by the scattered apothecia, dark discs and smooth thallodal border.

3. Lecanora tartarea, Ach v Syn. Lich. p. 172. Engl. Bot. 1. 156 et 1634.

Hab. Lord Auckland's group ; on the ground.

Specimens, apparently of this plant, are iu a very imperfect state, 4. Lecanora Parella, Ach., Syn. Lich. p. 169. Engl. Bot. t. 727.

Hab. Lord Auckland's group ; on the lulls.

Also in a very rudimentary state.
