lanceolate, obliquely cuneate at the base, margins cartilagi- 
nous and slightly undulate, sori somewhat reticulated usually 
interrupted. (T's. VII, VIII. C.)

Ogs. On account of the pinnz of this species being nar- 
rower than the simple fronds of the two first species, the 
venules are consequently shorter and therefore anastomose 
sooner, exhibiting a more uniform reticulated character: in 
that respect possessing some of the reticulated venation and 
sori of Hemionitis ; but in other particulars it bears no affinity 
to that genus. 
On several Mosses, new to the British Flora. By RICHARD 
Spruce, F.B.S. ie hb res x 
The mosses described in this and the following pages, for 
: the first time as British, comprise the whole of my additions 
_ to the Bryology of Great Britain (with the exception of those 
. included in my paper on the ** Musci and Hepatice of Tees- 
dale," in the 2nd volume of the Transactions of the Botanical 
. Society), together with five species and one variety disco- 
- vered by my excellent friend, Mr. Borrer, and now published 
With his kind permission. Of the twenty-one species de- 
tected by our joint researches, four have never before been 
. described; those which have been figured in the * Bryologia 
- Europea” have all been authenticated by comparison with 
Specimens from the learned authors of that work ; and the 
. Temaining species have been ascertained by means of exam- 
. Ples received from Messrs. Bruch, Wilson, Taylor and Mon- 
. fagne, and in most cases confirmed by the personal examina- 
. Uon of those distinguished cryptogamists themselves.
