ADDENDA.

The following are stated to have been collected on Mount Franklin, by Mr. Park of the Geological Survey Department, on the authority of Mr. J. Buchanan ("Trans. N.Z. Inst.," vol. xvii., p. 356):

Ranunculus lyallii, Hook. f.
Cotula pectinata, Hook. f.
Gentiana concinna, Hook. f.*

Veronica linifolia, Hook. f.

"Mitrasacne cheesemanii," J. Buch.

Ourisia macrocarpa, Hook. f.

Carex wakatipu, Petrie.

* Hitherto this species has only been recorded from the Auckland and Campbell Islands, and it is to be feared that a clerical error has occurred, Mount Franklin being a most unlikely habitat for a plant that can only exist when growing in peat.

ART. LIV.-On a new Variety of Desmid.

By W. M. MASKELL, F.R.M.S.

[Read before the Wellington Philosophical Society, 24th February, 1886.] Genus Triploceras, Bailey.

Triploceras tridentatum, Maskell; var. superbum, var. nov. Frond slender, elongated, cylindrical, very slightly depressed at the middle.

Denticulate lateral projections of the segments large, some

what prominent, tri-dentate, the middle tooth the largest. Edges of frond between the projections slightly curved inwards, so that the segments appear as if with several toothed transverse rings. Denticulations pointing at right angles to segment near the constriction, and slightly forward near the extremities. The small processes at the base of the terminal tridentate prolongations sharply pointed forwards, not tri-apiculate. Terminal processes, 2, sub-rectangular, tri-dentate.

Endochrome, not very dark
