had been cleared away. E. B. Chamberlain,* having received specimens 

 of an unknown Cathariium from Maine, has ascertained that it is 

 identical with G. Macmillani of Holzinger, whose description he re- 

 publishes, with new figures and new records of the plant's distribution. 

 It occurs in Minnesota, Missouri, Connecticut, New Jersey, Maine. 



Mexican Mosses-f — A. Geheeb gives an account of the vicissitudes 

 that have attended the determination of a century of mosses collected by 

 Sartorius in Vera Cruz, Mexico, in 1<S80, 1883, 1884. Among them is 

 Rhodobryum Levieri, a new species ; and two American species are 

 recorded for Mexico for the first time. 



Hypnum riparium L. in New Zealand.^— H. N. Dixon recapitulates 

 the evidence against the occurrence of this species in New Zealand ; but 

 is able to record the indisputable existence of an aquatic form of the 

 species near Hnnterville, north of Marton, in the North Island, wdiere it 

 was found by C. J. Burgess in 1905. It was also gathered by J. 

 Drummond on the Swan River, West Australia. 



Fissidens algarvicus Solms as a British Moss.§ — H. N. Dixon 

 records the discovery of this moss in England, collected by Gr. B. Savery 

 on red sandy shale near Exeter in the early spring of this year. Various 

 authors have referred F. algarvicus to F. incurvus, F. pusillus, F. viri- 

 dulus, etc., as a variety. But Dixon shows that it is distinct from these 

 species and also from F. intraUmbatus ; that it exhibits more similarity 

 to F. Orrii — an immigrant of the Glasuevin garden — bat is distinguished 

 by certain leaf -characters ; and finally that it is identical with F. sor- 

 dagnai, so far as can be judged from V^enturi's description of that 

 species, save in the one character o? the sculpturing of the spores. 



Distribution of Fissidens grandifrons.|l— A. .Geheeb reports having 

 found in a collection of mosses collected by W. Schimper in Abyssinia 

 a specimen of Fissidens grandifrons, for which the only African locality 

 previously recorded was Algeria. The collection was received from 

 Stephani, and was probably one of the sets issued by Hohenacker. 



Philonotis adpressa Ferg.,a False Species. 1" — G. Desmier discusses 

 the history of Ph'donoUs adpressa Ferg., which has been shown by 

 Loeske to be, not a specific type, but a series of forms artificially united 

 under a common superficial character, and belonging, some to P.fontana, 

 some to P. seriata. The author describes the special characters which 

 these forms have in common ; and calls attention to a particular 

 specimen gathered in Haute- Vienne by Lachenaud, over which experts 

 have disputed, and which he himself is convinced must be referred to 

 P. ccBspitosa. Accordingly he names it var. adpressa of this species. It 

 is a confirmation of Loeske's theory as to the parallel forms observable 

 in the different hygrophilous species of Philonotis.
