NOTE. 
I find that Weisia mucroiiulata Bruch is described on page 158 in Vol. 
IV, Part I of Sprengel’s Linnsei Systema Vegetabilium (1827). The first 
eighteen words of the last paragraph of my article in the March Bryolo- 
gist consequently become irrelevant, and the reference to “ W. mucron- 
atula" in Paris’ Index Bryologicus (p. 1365) under Weisia mucronata is 
shown to be incorrect. At the same time I would suggest that the word 
“ quoted ’’ in the first paragraph of my article be changed to translated.

SUPPLEMENTARY NOTE. 
Owing to the thoughtless omission of a certain sentence from the first 
paragraph of my article in the March Bryologist (which paragraph was 
hastily condensed just before going to press) a wrong impression may have 
been conveyed to some of the readers of the article— an impression which 
would be unfair to Prof. Holzinger. In order to counteract any such possi- 
ble impression I wish to say that Prof. Holzinger cannot justly be held 
for the errors cited, because they appear in his stated source of information, 
and, furthermore, they were, in his article, inclosed within quotation marks. 
His purpose, which is seen to be fully served by an exact translation, and 
my own in calling attention to certain erroneous citations, have no direct 
bearing whatever upon each other. My object in citing portions of his arti- 
cle was simply to make my own more intelligible by referring directly to an 
article which was accessible to all. 
Prof. Holzinger suggests that “ is also removed ” which appears on page 
8 (line 22) of the January article be changed to “is retained’' (i. e. as a 
Hymenostomuiri). J. Franklin Collins.

A CORRECTION. 
Thanks to Mr. Collins’ note on Some Erroneous References in the March 
Bryologist, I am able to make an important correction in my translation: 
the word “ fortgefiihrt,” rendered by me “removed,” must be rendered 
“ retained in the genus.” 
Then I also thank Mr. Collins for his correction in the above note sub- 
stituting “ translated” for “quoted.” It was entirely foreign to my purpose 
to criticise Mr. Limpricht’s page references ; the simple translation was all I 
needed, and the references, erroneous or right, had no bearing on my point. 
John M. Holzinger. 
Mr. J. F. Collins has called my attention to the fact that Dixon has named 
a Brachythecium rivulare tenue so that my name is untenable. For the 
variety described in the April Bryologist under this name I propose the 
name B. rivulare LAMOILLENSE. A. J. Grout.
