ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 339 



Leucolejeunea, a New Genus of Hepaticae.*— A. W. Evans sepa- 

 rates off from Archil ejeuma Schiffn. a new genus, Leucolejeunea, proposed 

 for the reception of three North American species, A. clypeata, A. 

 Sdlowiana, and A. conchifolia, described (or redescribed) and figured by 

 the author six years ago. And with them he associates A. xanthocarpa, 

 of wide distribution within the tropics and outside, and also A. rotundi- 

 stipula, a Cape species. He gives a detailed description of the genus, 

 and, having had the opportunity of studying the type-material of 

 Lejeunea unciloba Lindenb., he is able to show that it agrees with 

 A. Sellowiana and takes precedence of it. 



Bryological Notes.t — V. Schiffner publishes a continuation of his 

 notes upon Bryophytes. 88. Cephalozia connivens has been found among 

 some North American material of Telaranea nematodes, and is thus 

 shown to be a circumpolar species. 39. C. gracillimavar. viridis Douin, 

 hitherto recorded only for France, has been found in Dalmatia. 40. 

 Scapania calcicola Ingh. is distinguished from 8. aspera by having larger 

 leaf-cells, and a new form of it is described. S. calcicola was first found 

 in Sweden and France ; it is absent from England, but has recently 

 been found in Bosnia and Lower Austria. 41. Riccia pseudo-Frostii 

 Schiffn. receives a more complete description, founded upon material 

 gathered near Regensburg by Familler. The openings of the air-cells 

 do not arise by resorption or dying off of epidermal cells. The species 

 has been found by Nicholson in Sussex. 42. The vegetative repro- 

 duction of Leptoscyphus cuneifolius, a rare and sterile European species, 

 is brought about by the breaking off of the small obcuneate leaves at 

 their bases. These are carried away by wind or water, and sprout at 

 their margins. A similar process occurs in some tropical species of 

 Plagiochila. 



European Hepaticae.J — K. Miiller publishes the sixth part of his 

 monograph of the " Lebermoose " in Rabenhorst's Kryptogamen-Flora, 

 treating of the following genera : — Riella (continuation with descriptions 

 of five more species) ; Aneura (6 species) ; Metzgeria (4) ; Blyttia (1) ; 

 Mbrckia (3) ; Pellia (3) ; Blasia (1) ; Petalophyllum (1) ; Fossombronia 

 (generic description). Figures of each species are supplied. 



Mosses of Sussex.§ — W. E. Nicholson publishes an enumeration of . 

 the mosses of Sussex, comprising 344 species and numerous varieties. 

 In an introductory note he gives a sketch of the geology and physical 

 geography of the county, a brief account of the principal bryologists 

 who have collected in Sussex, and a list of papers in which previous 

 records have been published. Nearly all the species in the present 

 enumeration have been actually observed in the field by Nicholson him- 

 self during the last fifteen years. He adds a list of 15 more species 

 which have been found just outside the borders of the county, and may 

 reasonably be expected to occur in Sussex itself.
