they taper to the base aud apex, and nre pretty regularly dichotomous, with more or less intermixture of lateral
branches. The axils are all rounded, the apices attenuated and acute. Sometimes there are few or no lateral ramuli
; in other specimens they arc numerous, and frequently strongly hooked backwards, or converted into clasping
tendrils. The cystocarps are sessile on the branches, and mostly tipped with a strong subulate horn. The colour
is a dark brown-red. The substance is firm, and the plant imperfectly adheres to paper in drying.

Hab. At the mouth of the Tamar, W. H. 11.
Fronds 6 -8 inches long, and as much in the expansion of the laciniæ, foliaceous, deeply divided in a dichotomous
manner, sometimes rather irregidarly multifid, the segments euneate, from half an inch to an inch in breadth,
the terminal laciniæ gradually narrower, the apices subacute and fastigiate. Colour a rather pale rose-red, occasion-
aUy deeper. Substance veiy soft, somewhat gelatinous on the surface. The plant closely adheres to paper. The
cystocarps, which are densely scattered over the frond, resemble those of a Callophyllis in structure.—The structure
of the frond agrees «fith Agardh’s description of that of his Folycoelia taciniata, a plant from 'Western Australia,
unkuown to me, but which perhaps may be specifically as weU as generically identical with wlial is now described.
Not having seen a specimen of the B est Australian plant, I think it best, for the present, to give a name to the
Tasmanian. I recently distributed it as a Callophyllis, having placed it, without examination, in that genus from
its strong external resemblance to C. P l a t e CXCII. B. Fig. 1, a frond, nat. size; 2, section through

A beautiiul speeies, elegantly perforated like an Agarum. I first found it in Western Austridia; and afterwards
coUected it in greater plenty at Port PhiUip Heads. It appears to be of very rare'occurrence in Tasmania. (Local
name, “ The Holy Coat.”)

H ab. Georgetown, W. II. H.
Fragments of a Kallymenia of large size, resembling K. Harveyana, are not uncommon at Georgetown, but 1
have as yet seen no specimen sufficiently perfect to enable me to characterize the species. Oue of my specimens is
18 inches broad, about 13 inches long, broacUy foliaceous, lobed and lacerate at the margin; another, of somewhat
smaller size, is deeply laciniate, and divided into numerous narrow lobes and segments. Tliere seems to be no very
defiaite outline. There is a short stipes, soon widening into the euneate base of the frond. The colour is a deep
crimson. The substance is soft, and the plant adheres firmly to paper.
