It is probable that some of the specimens referred to may prove distinct. The fertile plants correspond with 

 European specimens, but there are some barren ones which are much elongated and branched, and are nearly 

 destitute of rootlets beneath ; these have a different look, which may be due to local causes. The Dendroceros 

 leptoliymenius, so fully described by Dr. Taylor, differs in appearance from the common prostrate forms of this plant. 

 No New Zealand specimens of Antlioceros punctatus, Linn., have been seen, those so named by Dr. Taylor be- 

 longing to A. lavis. The A. punctatus, from Hennite Island, is apparently the Dendroceros Jamesoni (Tayl. in 

 Lond. Journ. Bot. 1848, p. 285), which, however, can hardly be compared with Dendroceros crispatus, Hook. 



2. Antlioceros Jamesoni, Tayl. ; fronde enervi plana dissecta lseviuscula margine minute lobulata, lo- 

 bulis undulatis crenatis, involucro oblique truncato kevi, capsula longiuscula valvis apice cohserentibus.

Also found at Cape Horn (barren), J. D. H. ; and at Quito (with perfect fruit), Prof. Jameson. — This species 

 differs from all others excepting A. giganteus, Lehm. et Ldbg., in the crenate laciniaB of the margins of its fronds, 

 which, however, are much more minute than in that species, a character of degree only, and perhaps not constant. 

 The fronds of A. giganteus do not always show the nerve very distinctly, particularly in the part above the involu- 

 erum. The transition of Antlioceros into Dendroceros would appear to commence with A. Jamesoni, and there re- 

 mains only the adhesion of the valves of the capsule on one side to distinguish the genera ; an unsatisfactory cha- 

 racter, for in D. crispatus the valves are sometimes as much separated as in A. punctatus. So far as can be judged 

 from the figure, Monoclea Forsteri, Hook., differs scarcely at all in structure from Antlioceros Breutelii, Gottsche ; 

 and these two species may therefore prove congeneric, if the absence of the columella be considered a sufficient cha- 

 racter to distinguish them from Antlioceros, with which they are in every other respect almost identical.

4. Antlioceros Colensoi, Mitten; fronde late nervosa inordinate subpinnatifida margine lobulis fla- 

 bellatis crenulatis sinuatisque preedita, involucro ruguloso, capsula arcuata uno latere tantum dehiscente, 

 pedunculo incluso.

Fusco-niger. From 1-2-pollicaris, vage ramosa, dorso ventreque lsevi, margine irregulariter subpinnatim lobato, 

 lobulisque parvis pallide pellucidis sinubus rotundatis quasi perforatis onusta. Involucrum plicis parvis rugulosum, 

 apice subbilabiatum. Capsula pallide fusca, breviuscula. 



A curious species, differing from A. Javanicus, Nees, in the much less laxly areolate lobulate margin of its 

 fronds. It has also considerable resemblance to A. glanduloms, Lehm. et Lind., another Javan species ; but although 

 the habit appears to be very similar, the form of the lobules on the margin is totally different.
