A CORRECTION BY DR. I. HAGEN. 
In the September Bryologist, page 82, towards the end of the article 
after the words, Mr. Stuntz quotes: please read as follows: 
HypJium ornithopodioides Scop. FI. Cam. p. 104 (1760). 
Hypnum complanatum L. Sp. PI. p. 1588 (1763). 
Instead of 
Hypnum complanatum L. Sp. PI., ed. i, p. 1123 (1753). 
Hypnum fronde subpinnata ramosa, foliis pellucidis acutis pla 7 iis Scop. 
FI. Cam., ed. i, p. 150 (1760). 
Hyp 7 iu 7 n ornithopodioides (nec. L. nec. Huds.) Scop. FI. Cam., ed. 2. 
II, p. 329 (1772). (The last two on the authority of Bridel.) 
Dr. Hagen wishes to bring out that there was opposition between the 
first two and three following names, the words “instead of” by occupy, 
ing a separate line brings this contrast out. — Editor
