forms, arc discussed critically. Three rarities — Acrobolbus Wilsoni, 

 Plagiochila tridenticulata, Leptoscyphus cuneifolius — were supplied to the 

 author from the west of Scotland by S. M. Macvicar. 



Calypogeia in Italy.* — C. Massalongo publishes a monograph of the 

 Italian species of Calypogeia. He gives new descriptions of the genus 

 and various species and varieties. He maintains four species— 6'. Tri- 

 chomanis, C.Neesiaaa, C. suecica, C. arguta — under 0. Trichomanis are 

 four varieties : communis, flssa, Sprengelii, gracilis, and a subspecies, 

 G. Miilleriana. Critical notes are added, and attention is called to other 

 species which are likely to be found within the limits of Italy. 



Cephalozia in Scandinavia.! — H. W. Arnell and ; C. Jensen describe 

 and figure some rare Scandinavian species of Cephalozia, from the original 

 specimens preserved in the herbarium of Helsingfors University, viz. 

 C. boreal is Lindb. (1887), C. subsimplex Lindb. MS., C. spinigera Lindb. 

 (1879), C. lacinulata Spruce, and C. (Prionolobus) Perssonii Jensen sp.n. 



Notes on Californian Hepatics4 — H. B. Humphrey publishes 

 some studies on the physiology and morphology of some Californian 

 hepatics. Certain species are infested with fungi, parasitic in the case 

 of Fossombronia longiseta, symbiotic in the case of Fimbriaria californica, 

 epiphytic in the case of Aneura multifida, Anthoceros Pearsoni, and 

 Porella Bolanderi. Fertilisation takes place in Fegatella conica during 

 early spring ; but the spores do not mature until the following January, 

 having passed through the intervening dry season in the tetrad stage. 

 The dry season leads to other adaptations, which are noted. It is fatal 

 to hydrophilous species, but not to xerophilous species, these latter being 

 able to resume growth from thallus or spores even after complete desic- 

 cation. The spores of some xerophilous species are capable of germina- 

 tion after two years. 



Antarctic Hepatics.§ — F. Stephani gives an enumeration of the 

 hepatica? collected by Skottsberg in Tierra del Fuego, the Falkland 

 Islands, South Georgia, and the neighbouring Antarctic regions. There 

 are seventy-eight species, five of which are new to science. 



Illustrated Key to the Genus Lejeunea.|| — Lacouture publishes an 

 analytical and synoptic key of the forty-three subgenera or genera into 

 which the old genus Lejeunea is now divided. He gives a typical figure 

 of each in illustration of the text printed opposite to it. The drawings 

 have been made from nature, from sketches made by Spruce, Schiffner, 

 and Stephani respectively. 



Morphology and Anatomy of Bucegia romanica.1[ — Y. Schiffner 

 gives a detailed and illustrated account of the structure and develop- 

 ment of the rare hepatic Bucegia romanica, based upon an examination
