An apology is certainly necessary for giving so very imperfect 
an account of this species of a Genus requiring more than an 
ordinary degree of care in its investigation. The fact is, the 
drawing was made by Dr J. D. Hooker, and the plate prepared 
previous to his departure on the scientific voyage in the southern 
hemisphere under Capt. James Ross: but the specimen and 
original drawing, and the notes made by him, have been nislaid, 
and the above is all the information we can venture to give. 
Our impression is that the species is one of Dr Jameson’s from 
Pillzhum. We trust at some future time to make up for our 
present deficiency of knowledge relative to this Moss.
