MUSCl MEXICANI. 
Elizabeth G. Britton. 
The first Century of C. G. Pringle’s Mosses of Mexico was received on 
July 15th. It includes ninety-four species of which thirty-one are new and 
four belong to new genera, three are new combinations and five are new 
varieties and two new records for Mexico; a remarkable series of novelties as 
M. Cardot, who has named most of the new species, claims them to be! The 
specimens number one hundred and twenty-two, in some cases as many as 
four numbers are given for one species, they are generous in quantity and 
generally in good fruiting condition, thus constituting a valuable and most 
interesting addition to American Exsiccatae. But we are surprised to see 
that the labels are headed P'lantae Mexicanae and not Musci Mexicani as 
the list issued with the set calls for, and the numbers are the collection 
numbers. 
The new genera are Dactylhymenium P ring lei (Britt.) Card., 
Husnotiella revoluta Card., P ringleella pleuridioides Card, and Synthe- 
todontium Pringlei Cardot which would at first sight be taken for a 
Tortula. 
The new combinations are Metzleria leptocarpa (Sch.) Cardot which is 
the same as Atractylocarpus mexicanus Mitt. ; Octodiceras mexicana 
(Sch.) ( Conomitrium mexicanum ) and Symblep/iaris Schimperiana (Par.) 
Card. 
The two new records for Mexico are Fissidens asplenioides and Poly- 
trichum commune. Diphyscium foliosum and Hymenostylium curvirostre 
also seem to be extension of ranges. 
Of the thirty one new species it is impossible to give a quick verdict, as 
they will necessarily require some study and comparison; but Trematodon 
Lozanoi is most interesting, belonging close to the South American T. gym- 
nostomum Lindb. but differing in size, annulus, etc. One of the most inter- 
esting species of the old ones is Bryoxiphium mexicanum which for the first 
time is issued in fruit. The capsules agree in all essentials with those of 
Br. Norvegicum. 
Two interesting reductions are made, Poly trichum j uniperiforme Sch. 
and P. Ghiesbreghtii Besch. are reduced to P . juniperinum. A few typo- 
graphical errors have been made in the labels and list, and a few differences 
of usage in generic names as A trichum and Diphyscium are noted. 
We heartily recommend this set to all students of American mosses.

Wanted. — Miss Caroline C. Haynes will be grateful for fruiting speci- 
mens of the genus Sphaerocarpus from tropical European and American 
stations. These will be returned to the owners, or exchanged for local 
species. Address Highlands, New Jersey.
