230 HYPNUM EXANNULATUM AND H. ADUNCUM, 
nulatum as a new and rare species known only from Cheshire (vide 
p.120). It is evident that both these are the same, and that he is un- 
acquainted with the true H. aduncum. 
. The synonyms of the three species are then as follows :—

I am indebted to Messrs. Baker, M‘Kinlay, and Davies for speci- 
mens of H. ezannulatum from various localities. It is widely distri- 
buted all over the country, and is not very rare in fruit. H. aduncum, 
L., and Br. and Sch., has, as far as I know, only been noticed at South- 
port, Lancashire, from which place there are specimens in the Herba- 
rium of the British Museum, collected by Mr. Wilson, June, 1858. 
A new species, H. pellucidum, Wils. ms., has been discovered by him 
at Wyburnbury Bog, Cheshire. This is Z7. vernicosum, Lindberg, and 
H. aduncum, var. 8 tenue, Bryol. Eur., according to Berkeley ; and 
H. aduncum, var. B tenue, Wils. Bryol. Brit., according to Mr. G. E. 
Hunt (in lit.). 
I append a list of the British species belonging to that division of 
the genus to which Sullivant has given the name Harpidium, taking 
the description in Bryol. Eur. in accordance with Berkeley's determina- 
tion as that of Wilson's H. pellucidum, with which I am yet unac- 
quainted.
