and 29 hepatics have been gathered in that region, and of these 128 

 mosses (73 p.c.) and four hepatics (14 p.c.) have proved to be new to 

 science. 



Mosses of the Belgian Congo.* — J. Cardot publishes preliminary 

 diagnoses of mosses collected in the Belgian Congo by Laurent and 

 Paque, and near Oussouye on the Casainance by Mathieu. He hopes 

 later to give fuller descriptions accompanied by figures. Eighteen 

 novelties are described, and most of the specimens from the French 

 Congo are previously unknown species of Fissidens or Galymperes. 



Mosses of the Philippine Islands.f — V. F. Brotherus publishes a 

 list of 98 mosses collected in the Philippine Islands by Merrill and 

 others. Twenty-two of the species are new to science. New also 

 is the genus MerriUiobryum, agreeing with Fabronia in structure of 

 stem and leaves, but differing much in its sporogonium. 



Hepatics of New Caledonia. J — E. G. Paris gives a list of 16 

 hepatics collected by Le Kat in New Caledonia, and determined by 

 Stephani. None of them are new to science, but some are recorded for 

 New Caledonia for the first time. 



Studies of Javanese AnthocerotaceaB.§ — D. H. Campbell has pub- 

 lished studies on some Javanese Anthocerotaceae. He separates off from 

 Anthoceros certain species, which had been grouped together on 

 account of their spiral elaters and the absence of stomata on the sporo- 

 gonium, into a new genus Megaceros, which has the additional characters 

 of multiple chromatophores and green spores. Two new species from 

 Java are added. They are both monoecious. The thallus-form and 

 apical growth and archegonia are as in typical Anthoceros ; the large 

 solitary antheridium is more like that of Dendroceros. The early 

 divisions in the embryo recall Dendroceros ; the amount of sporogenous 

 tissue is great as in Notothylas. As in Anthoceros, the primary chromato- 

 phore of the spore-mother-cell divides into four before the nucleus 

 divides ; the spores are small and thin- walled and contain a large chloro- 

 plast. The elaters are multicellular as in Dendroceros. The sporophyte has 

 much green tissue but no stomata ; the cells contain 2-6 chromatophores. 

 The foot is large and has root-like extensions. Campbell also treats of 

 Notothylas javensis and of two unnamed Javan species of Dendroceros. 

 Finally he discusses the affinities of the Anthocerotaceae, and would 

 keep them in a special class distinct from both Marchantiales and 

 Jungermanniales, though perhaps approaching somewhat to Cyath odium 

 in the former of these two. 



Antiquity of the Hepaticse.|| — D. H. Campbell discusses the 

 distribution of the Hepaticaa and its significance. He is strongly of 

 opinion that, though fossil remains of indubitable Bryophytes are very
