found at two stations in Sussex b}' W. E. Nicholson. Owing to 

 its large air cavities it might be confused with i?. crystallina^ but 

 the latter is always green or yellow-green and never tinged with 

 violet. 2. Lophosia badensis Schiffner has been much confused with 

 L. turbniata Steph. and to some extent with small forms of jL. i1ifw^//m. 

 This confusion has been cleared up by Schiffner. Macvicar cites 

 stations for L. badensis in Yorkshire and Scotland, describes 

 the salient points of all three species, and shows how Lindenberg's 

 Jiingermannia acuta (a mixed species) has added to the confusion. 



3. PrioMolobtis striatulus Schiffn. has been found in Lanarkshire 

 by Macvicar, where it occurs at an altitude of 1900 ft. growing on 

 masses of decaying Sphagmmt , associated with Vaccinitun Myrtillus, 

 Efnpetrum and Polytrichiim. It occurs in Sweden, Denmark and 

 France. In the latter country it had been mistaken bj' Boulay for 

 Cephalosia Elachista which, according to Douin, has not been found 

 in France. Lately C. Elachista has been found in Sussex by 

 Nicholson, the only previous British Station being in Ireland. 



4. Cephalosiella integerrinta Warnst, was found by Nicholson in 

 Sussex at two stations. Macvicar shows how it differs from C. ^ryÄw« 

 Kaal. and resembles C. pirißora Douin. A. Gepp.

 Mosses. (The Annais of Scottish Natural History. n^. 58. p. 106 — 113. 

 Edinburgh 1906.) 



The author describes the following new Scotch species and 

 varieties: Cynodontium asperelhirn, Campylopus prasinorufus, C. 

 rubiginosus, C. purpurascens var. Kinlayanus, Barbida viridescens, 

 Leptotrichum confertu^n, Hypnum anotnalum, Plagiotheciuin tricho- 

 deuin, Ceratodon conicus var. acicularis. Also Campylopus Dickieanus 

 from Lake N5'ami in Central Africa. He finds Didymodon Jenneri 

 Schimp. (1868) to be synonymous with Cynodontiurn laxirete Dixon, 

 with C. polycarpoides Stirt. and C. polycarptan var. laevigattanHa-gen., 

 and rechristens it C. Jenneri. Under Dicranidia fuscorufa he gives 

 details of what is apparently a new moss previously mistaken for 

 Dicranella curvata. Barbida assinmlans Stirt. he lowers to a var. of 

 B. insidana. He redescribes Leptotrichtitn conipactuni Stirt.

 of Australia and Tasmania, collated from available Publi-

The authors, seven years ago, prepared a catalogue of 500 

 species of mosses found in New South Wales, but withdrew it and 

 substituted in its stead this Census of Australian mosses which 

 comprises 918 species of acrocarpous mosses. The compilation was 

 rendered very difificult by the inaccessibility of specimens and de- 

 scriptions, many new species being known only by name in Australia, 

 and b}' the differing principles of determination adopted by specialists.
