Acromastigum, Badula. In the Frullania type the branch represents 

 the ventral half of a lateral segment ; in the Microlepidozia type the 

 dorsal half ; in the Acromastigum type one of the halves of a ventral 

 segment ; in the Radula type a part of the ventral half of a lateral 

 segment. 2. Intercalary branches may be either lateral or ventral in 

 position. 



Abnormality in Mosses.* — H. N. Dixon describes and figures two 

 cases of structural abnormality in the leaves of mosses — a bitid leaf of 

 CampyJopus flexuosus and a leaf of Tortida muralis with fragmentary 

 adventitious nerve. 



N. Arnaoudofff discusses some teratological instances observed in 

 mosses — a double nerve in Desmatodon latifolius, a costal lamella in 

 Mnium punctatum, duplication of leaves in the same species, twin sporo- 

 gonia in Ditrichum tortile. 



Chiloscyphus.J — V. Schiffner publishes a critical revision of the 

 European forms of the genus Ghiloscgphus based on phylogenetic con- 

 siderations. The European forms all Ijelong to one group and are nearly 

 allied to one another. The author discusses the following species, their 

 forms, distribution, microscopical characteristics, etc. : O. polyanthus, 

 C. paUescens, G. lophocoleoides, G. adscendens, G. fragilis, G. rivularis, 

 G. Nordstedii (a new species), Heteroscyplius deiiticulatus (Madeira and 

 Canaries). Schiffner gives a detailed summary of his results and appends 

 a revision of all specimens of Ghiloscyphus published in essiccatae. 



Bryosedgwickia, a New 6enus.§ — H. N. Dixon gives an account of 

 Bryosedgtvickia, a new genus of Entodontacete, collected in Western India, 

 and with it a list of some fifty Indian species collected partly in the 

 Nilgiris, partly near Darjeeling. Four of these are new to science and 

 are described ; and critical notes are appended to several of the others. 



Claopodium in Europe.! — ^^ • ^^- Nicholson discusses the genus 

 Claopodium, which resembles Thuidium in the papillose areolation and 

 the form of the leaves, but differs in the absence of filamentous para- 

 phyllia. He shows that its species are not confined to North America 

 and Asia, but that one species occurs also in Portugal. This is the 

 Leskea{?) aJgarvica of Schimper (I-STG). In May, I'Jll, Nicholson and 

 Dixon found the moss in its locus classicus and elsewhere in Portugal, 

 Upon studying the structure of the plant Nicholson came to the conclusion 

 that it is identical with the North American Glaopodium Whippleanum 

 and G. leuconeuron. It thus adds an item to the small list of Southern 

 species common to Europe and North America. 



Lepidozia setacea.H — E. J. Hill publishes some notes on Lepidozia 

 setacea found among other hepatics associated with Sphagnum in New 

 York State. He describes the small rhizoids or haptera by which the 

 hepatic attaches itself to mosses, and he speculates as to whether these 

 organs of absorption as well as of attachment.
