ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 337 



Netherton, near Liverpool. It is an addition to the British flora, and 

 grows erect in an ancient bog with Sphagnum obtusum, S. teres, Minium 

 affine and Hypnum cordifoliutn. A second station for the plant is near 

 Rainford Junction, Lanes. 



Hepaticse of Bermuda.* — A. W. Evans gives a list of the hepatics 

 of Bermuda, of which not much was known previously. Mitten, in 

 the 'Challenger' Report (1884), recorded 6 species ; since then 3 more 

 species have been added. Evans has worked up 6 recent collections, 

 and raised the total of species in the Bermudan flora to 23. The 

 affinities of this subtropical flora are with that of the Eastern States, 

 where more than half the species are found. Twelve occur in the 

 British Islands, and about as many in the West Indies. The one new 

 species, Grossotolejeunea bermudiana, is of tropical American affinity. 



Hepaticse of New England.f — A. W. Evans publishes the fourth 

 and final part of his notes on New England Hepaticse. He says that 

 but few additions have been made to the flora of New England during 

 the past year, and that most of the additions here noted have come 

 to light through the study of old material. All the species mentioned 

 in this contribution, with the exception of Frullania arborescens, are 

 common to Europe. Notes are added on species from Rhode Island 

 and from Cumberland, Maine ; and the census of New England species 

 completes the paper. 



Hepaticse of Puerto Rico.J — A. W. Evans contributes the sixth 

 part of his studies on the hepaticae of this region. It includes the 

 genera Cheilolejeunea, Rectolejeunea, Cystolejeunea, and Pycnolejeunea. 

 The second and third of these genera are new. Rectolejeunea contains 

 4 species, one of which is new ; Cystolejeunea contains one species 

 formerly known as Lejeunia lineata Lehm. and Lindenb. Critical 

 notes and detailed descriptions are appended to the species names, 

 together with synonymy. 



Hepaticse of New Caledonia.§ — E. G. Paris gives an interesting 

 list of hepaticae collected by MM. Etesse and Le Rat in the south of 

 New Caledonia, and determined by Stephani. Of the 53 species re- 

 corded, 19 are new and 9 are endemic. Three other genera are 

 represented by fragments of plants, which are insufficient for specific 

 determination. The above proportion of endemic species is unique. 



Riccia.|| — C. E. Lewis describes the embryology and development of 

 Riccia lutescens and R. crystallina. The former species is shown to be a 

 terrestrial form of Riccia nutans. It is monoicous, and produces 

 antheridia and archegonia in the autumn and ripe spores in the following 

 spring ; it is also propagated vegetatively by the separation of thalline 

 branches. In both this species and in R. crystallina the development 

 of the sexual organs and fruit agrees with that described for other species
