occurrence of Amphidium lapponicum Schimp. in the Hohe Tatra, where 

 it forms small patches in rifts in the granite irrigated by icy-cold water. 

 M. Peterfi * describes Bryum HazsUnszkyaiium, a new species of the 

 section Ptycliostomum and closely allied to B. pendulum. It occurs on 

 the walls of the basilica at Esztergom. I. Gyorffy t records the occur- 

 rence of the rare moss Molendoa Honisrhuchiana Lindb. at five stations 

 in the Hohe Tatra, on moist shady rocks. He has discovered Neckera 

 complaiiata var. longifoUa and Gathariticea imdulata var. polycarpa, which 

 are also additions to the Hungarian flora.

Mosses of Central Asia. J — -V. F. Brotherus gives an account of the 

 mosses collected l)y Lieut. Olufsen during his second expedition to the 

 Pamir. Twenty-six species and four varieties are recorded, coming 

 mostly from the Pamir (18,000-14,000 ft.), and the Altai Mountains 

 (1)000-10,000 ft.). Three species are new to science. The species of 

 Bryum were determined by the late Professor Philibert, and are described 

 by Brotherus. Only four pleurocarpi occur in the list. 



Tropical Mosses.§ — E. G. Paris gives a short list of seven mosses and 

 two hepatics from the high frontier plateau between French Somaliland 

 and Abyssinia. One species is new. He also gives a list of 55 mosses 

 and 19 hepatics collected by Frere Apollinaire in the Columbian Andes. 

 Three mosses and one hepatic are new species. 



South American Mosses.|| — P. Dusen publishes a fourth instalment 

 of his contributions to the bryology of Magellan, West Patagonia, 

 and South Chile. He describes 25 new species, and adds critical notes 

 on species previously known. 



Musci Europasi exsiccati.lf — E. Bauer publishes a series of critical 

 notes on hx^ Musci Europceiexsiccati, series iii -v., containing descriptions 

 of new species, additional notes on some of the specimens in the two 

 previous series, and very detailed keys to the European species of 

 Campylopus, Dicranodontium, Metzleria, and Didymodon. 



Classification of the Harpidia.** — F. Renauld describes the principles 

 which he has adopted in classifying the Harpidia : — (1) to admit as 

 specific types only well defined and fixed species ; (2) to regard as 

 subspecies certain widely distributed derivatives from the types less 

 clearly defined and usually, but not absolutely, fixed in their characters ; 

 (3) to recognise certain groups of varieties or forms which interrelated 

 cluster round the species and subspecies ; (4) to distinguish among 

 these groups a certain number of well-marked varieties, especially those 

 which tend to become generalised through adaptability to their environ- 

 ment. The author then enters into details, and offers a series of critical 

 remarks upon the various species and forms, and their relationships, etc.
