CONTRIBUTIONS TO THE FLORA OF VICTORIA. 



No. V. — Description of New Species of Moss.* 



By Professor Mueller, Ph.D., &c., &c. 

 * Translated from the Latin by F, M. Reader, F.R.H.S. 

 Dawsonia VicTORiyE, n. sp., C. Mueller, in " Hedwigia," vol. 

 xxxvi., 1897. 



Dioicious ; stem short, simple or singly branched ; leaves on 

 the lower part of the stem minute, remote, with a red-brown 

 broader sheathing base ; more or less shortly lanceolate, entire 

 elamellose, reticulate with narrow, rather dense and short cellules ; 

 nerve broad, occupying the whole of the lamina. Cauline leaves 

 small, in a dense head, when moist rosulate-spreading, broadish 

 lanceolate, firm, with the margin remotely, indistinctly and spar- 

 ingly serrated, areolate with thickened hexagonal cellules ; base 

 short, broad, sheathing and of a pale or more of an orange- 

 colour ; nerve broad, lamellose, occupying nearly the whole of 

 the blade, remotely dentate at the back. 



Perichgetial bracts more or less numerous and short, ligulate- 

 obtuse, above thickened-areolate ; sheath rather long, pale, laxly 

 reticulated and deeply channelled ; nerve narrow, hardly lamellose 

 at the apex or elamellose, vanishing towards the apex ; the inner 

 bracts tender and quite entire. Seta of hardly an inch, thick, 

 red. Theca erect, small, globular-ovate. Calyptra and peristome 

 of the genus, but the latter split into very fine capillary teeth. 



Habitat. — On the ground, Doncaster, near Melbourne. F. 

 Reader, 27th July, 1884. Forwarded from Dimboola in 1892. 



Formerly I included this species in Dawsonia longiseta, HpL, 

 but it is separated from that species by all parts being smaller, 

 by the peristome being much finer, the cauline leaves less 

 serrated, and chiefly by the perichaetial bracts being very short 

 and ligulate-obtuse. The perichaetial bracts of D. longiseta are 

 similar to the cauline leaves, but smaller, whilst the inner ones 

 are coarser and excised-serrate. 



REVIEW. 



A List of Marine Mollusca of Victoria. By Agnes F. 



Kenyon. Melbourne, 1898. 

 This brochure of twelve pages cannot lay claim to much scientific 

 value, whilst any merit it may possess in that direction is set off 

 by the richness in mis-spellings, and though a partial rectification 

 is offered by a list of twenty-six errata, yet two of these require 

 re-correction. The practice of the British Museum, which is 

 widely followed by zoological writers, is to use all low-case type 

 for species names, but in the present list the opposite extreme 

 is in force, as all the species names, whether adjectives or nouns, 

 have commencing capitals.
