Having fallen into an error in the Linnwan Transactions, 
where I have described the teeth of this moss as 16 per parta ap- 
proximatis, whereas they are decidedly but 8 with a middle lon- 
gitudinal line, and having become possessed of noble specimens 
with every part of the fructification in the most complete state, I 
willingly publish another description and figure of it. ‘The eight 
teeth and the terminal fruitstalk constitute this plant an Ocfo- 
blepharum. 1 am doubtful, however, whether O. a/bidum has a 
mitriform ealyptra; and if it have, I should propose that the pre- 
sent subject be separated from it on that account, preserving to It 
Bory de St. Vinceut’s name of Orlhodon, The calyptra is a very 
striking object, and rendered more so by the long hairs spreadng 
every way. The whole plant inclines remarkably to yellow
