LIST OF SPECIES. 



1. FONTINALIS ANTIPYRETICA. Linn. 



On stones in streams— not uncommon. " Attached to wood and stones in 

 the Co. Antrim rivers." — Moore, Herb. Coll. Sc. Dublin. Woodburn, Six- 

 mile Water, Colin Glen (Antrim) ; in a well near Comber, and in stream at 

 Newtownards Glen (Down). — S. A.S. Very luxuriant specimens may be found. 

 I have met with examples having stems two feet in length. The fruit, which 

 is seldom abundant, is to be looked for near the base of the stem. 5-7. 



2. Cryphtea heteromalla. Dill. 



" Abundant on trees in Glenarm Demesne, but not common in Co. An- 

 trim." — Moore, Herb. Coll. Sc. Dublin. On an ash tree at Ballywalter (Co. 

 Down). — S.A. S. 



3. HOOKERIA LUCENS. Dill. 



Damp, wooded banks of streams in hilly districts. This beautiful moss is 

 widely distributed, but rarely abundant. ' ' On moist shady banks in northern 

 glens" — Moore, Herb. Coll. Sc. Dublin. Glenoe, Woodburn (Antrim) ; Cre- 

 gagh Glen, Dundonald, Holywood Wood, Drumbo Glen (Down). — S.A.S. 

 12-1. 



Neckera ptnnata is stated to have been found on trees in Colin Glen, near 

 Belfast, but I believe there has been an error regarding this : it is certainly not 

 there now. 



4. Neckera crispa. Dill. 



Frequent on rocks in mountainous localities. "In fruit at the head of 

 Glenariff, July, 1836." — Moore, Herb. Coll. Sc. Dublin. Glenarm, Sallagh 

 Braes, Black Mountain, and Colin Glen (Antrim) ; Newtownards Glen, Slieve 

 Donard (Down). — S.A.S. 



5. N. COMPLANATA. Linn. 



Trunks of trees, and rocks — not rare. ' ' Frequent on trunks of trees 

 through the Co. Antrim." — Moore, Herb. Coll. Sc. Dublin. Redhall, Knock- 

 agh, Colin Glen (Antrim); Glenmachan, Mealough Hill (Down). — S.A.S. 

 12-3.
