ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 325 



eluding 124 new to Alaska and 4G new to science, viz. 2D new species 

 and 1 7 new varieties. In this list are included the results of previous 

 collectors. 



J. M. Holzinger* in summarising the above announces that the 

 number of species now known from Alaska and the Bering Sea Islands 

 readies 350, without reckoning a number of doubtful species. 



Inconspicuous Mosses. t — J. M. Holzinger describes the haunts of 

 some of the minute mosses (Archidium, Phascum, &c.) that occur in 

 the upper Mississippi valley, which he has had under observation for 

 several years. They wither away soon after the snow has melted. 



Psilopilum.J — R. S. Williams publishes a critical note on the dif- 

 ference between P. tschuctschicum and P. arcticvm as illustrated by 

 specimens gathered in the Yukon and Klondike region by himself and 

 by Macoun, and concludes that the two species are sufficiently distinct. 



Mosses of East Greenland.§ — P. Dusen has worked up the mosses 

 collected by the Swedish Expedition under A. G. Nathorst to East 

 Greenland and Jan Mayen Island in IS!)',). The gatherings were far 

 from exhaustive ; hence the number of species enumerated does not 

 exceed 130. Hurry Inlet w T as the richest locality visited, but the 

 expedition made only a very short stay there. Five new r species of 

 Bryum are described. The climate is a dry one ; and the conditions 

 of drainage, of irrigation by melting snow, of soil, &c. which affect 

 the moss vegetation, are discussed. The special gatherings from the 

 fourteen chief localities visited are noted separately, and are followed 

 by a general systematic enumeration of the whole collection. An index 

 is supplied and a map of the voyage. 



The Moss Exchange Club || issues its report for 1903. The principal 

 feature is a list of the mosses and hepatics contributed by the members 

 for exchange. Critical remarks by the referees upon several of the 

 specimens are added. 



K. G. Limpricht.lf — V. Schiffner supplies a biography of the late 

 K. G. Limpricht, the distinguished German bryologist, who died at 

 Breslau last October in his sixty-ninth year, and who for many years 

 was lecturer in Natural Science at an Evangelical College in Breslau. 

 His high qualities as a systematist and biologist in the study of the 

 European MuscineEe are pointed out ; and a chronological list of his 

 publications — GO in number — is appended. The greatest of these — Die 

 Laubmoose Deutschlands, Oesterreichs nnd der Schweiz — a well-known 

 standard work on mosses in three volumes, is still incomplete. It was 

 begun in 1 885 ; and the lapse of time since the first part appeared has 

 necessitated the preparation of a supplement which is being issued by 

 the author's son.
