Enumeratio Muscorum Caucast. V.¥. Brotherus. (Acta Soc. 
Sci. Fenn. xix. 170 pp. quarto, 1892). 
This beautiful memoir is a very important contribution to 
geographical Bryology, and of much interest to American students, 
many of the species occuring on this side of the Atlantic. 
Although the author claims to follow Lindberg in the nomen- 
clature, we notice several discrepancies, which are interesting, as 
being also unlike Braithwaite’s accepted names—Lucalypta for 
Leersia, Mnium for Astrophyllum, Ulota for Weissia, Orthotri- 
chum for Dorcadion and Amphidium for Anetangium. The de- 
scriptions of new species are by Lindberg, Brotherus, Muller and 
Venturi, twenty-four Acrocarpi and ten Pleurocarpi being char- 
acterized. Four hundred and twenty Musci, six Spagna and 
thirty-four Hepatic are listed. E. G. B.
