NORTH DONEGAL MOSSES. 
By J. Hunter. 
Wate Mr. H.C. Hart’s Flora of Donegal has supplied botanists 
with a full account of the flowering plants, it is a matter of regret 
that so little has yet been done in the investigation of the Moss 
Flora of this interesting county. Mr. H.N. Dixon, in this Journal 
for December, 1891, pp. 859-362, has a short paper on the mosses 
collected by him during a brief visit in July, 1890, and this seems to 
be the last contribution to the very meagre bryological literature 
dealing with the county. During a residence of some years in the 
northern portion of Donegal, I paid a little attention to the mosses, 
but the list which I subjoin can hardly be considered as more than 
a partial contribution to the bryology of the district. As such 
however, it may possibly be considered interesting and suggestive 
in the absence of a more complete record. 
My investigations have been mainly confined to the valley run- 
ning from the city of Londonderry north-westward to Fahan, Lough 
Swilly, and thence along the eastern shore of the lough to Bun- 
crana, in the neighbourhood of which I have explored largely. I 
have also visited, but only for a few hours, a portion of the western 
shore of Lough Swilly, which is interesting as possessing features 
more characteristic of the Donegal landscape in its wilder aspect. 
In a little wood, named Carradoan, on the slope of a hill, I seemed 
to be transported to an altogether different climate. The mildness 
this group, and also with the Andree, and other similar ga 
whose absence in my list is accounted for by my not having ye 
explored the higher hills and mountains, which I hope, however, 
to do in the ensuing summer. . 
My thanks are due to Mr. H. N, Dixon and Dr. Stirton for
