1874) by thirty-seven years, it is the latter which must change 
its name, and the former must be dropped, as it is a mixed 
species founded on immature specimens. Fortunately there is a 
name which unquestionably belongs to B. Beyrichiania Sull., for 
in the description of it in L. & J. Manual, page 47, they say, 
«Sull. Icon. Musc. Suppl. 25, 2 75, partly made upon specimens 
of the next species.” 
The next species is B. brevicollis L. & J., founded on specimens 
collected by H. W. Ravenel, Santee Canal, South Carolina; accord- 
ing to their own citation, the very ones cited by Sullivant in the 
Icones Supplement under B. Beyrichiana. A further comparison 
of the descriptions in both will show that those in the Manual are 
transcribed from the Icones with a slightly incorrect modification, 
and a very imperfect characterization for their new species. Omit 
the words “its top not surpassing the leaves;” change “partly” to 
“entirely;” combine the two descriptions, omitting all references to 
B. Beyrichiana, and there will remain a good characterization of 
Ravenel’s specimens, with the additional evidence that the spores 
are large and rough in Ravenel’s specimens and are so figured in 
the Icones, but no mention is made of them in the Manual. 
That Sullivant should have drawn table 15 from several speci* 
mens is not probable, and contrary to what we know of his 
careful methods, furthermore the other specimens referred to in 
the Icones are preserved in the same cover with the above 
in Sullivant’s Herbarium. Those collected by T. P. James, 
at Burlington, N. J., are immature, but they do not agree with 
either of the above, when placed side by side under the same 
cover-glass. They have leafy stems 2 mm. high, but the leave? 
are subpapillose, and the pedicels stout and recurved with 1m- 
mersed capsules, not sufficiently matured to show the spores: 
They are probably immature specimens of B. Sudlivanti Aust 
Dr. George Vasey’s specimens from Illinois are also immature, st 
young that they are still acaulescent, the calyptra is only just 
formed and the capsule is yet a mere thickening of the stout, io 
curved pedicel. The leaves are subpapillose on the back, am 
specimens preserved in Austin’s Herbarinm, labeled “97 ese 
Beyrichiana, Ringwood, McHenry Co., Ill. collected by Dr. G° 
Vasey,” are corrected by Austin to B. Sullivanti Aust. It is
