at sea-level where the mountains adjoni the sea near New- 

 castle. The following are found in the Mourne mountains, 

 and some on Slemish and Fair Head, Co. Antrim : Andrecea 

 alpina, A. crasshiervia and var. Hu/itii, Oligoirichum hercy- 

 nicum (also on Cave Hill), Grhnmia funalis, G. robusta, 

 Rhacotnitriuin el/iptitum, R. ramulostivi, Dicranum Scottii, 

 D. fuscescens, Dierauodontium /ofi'^irostre var. alpinum (at 

 Cushendall), JFe/>era acuminata, IV. e/of/j^^a/a, Flai:,iobryum 

 Zierii (at Sallagh Braes and Cushendall), Tetraplodoii 

 jnnioides, Splachnuin a/npiiiiaceui/i, Hypnuni Jlui^fl/are, H. 

 sun/ienlosu//i. Of Hepatiac may be mentioned Scapaiiia 

 purpurea, A^ardia ccfiipressa, Anfhe/ia Ju/acea, Acolea oblusa, 

 and A. creuulata, a list which is chiefly remarkable for the 

 absence of northern and alpine species such as are found on 

 the higher mountains of Scotland. 



On the sea-coasts, Grimmia maritima and Ulota phyllantha 

 grow on rocks close to tide mark, and Tortula inclinata in 

 the chinks; while on the sandhills at Newcastle have been 

 found Tortula ruralipormis, Bryutn roseuin, JSIniuni cuspi- 

 dal utn, Jyrachvthedu/n albicans, and Morikia hibeniica. 



Many species grow on the extensive peat bogs and 

 marshes which are spread throughout the two counties, 

 but with the cutting out of the bogs and drainage are not 

 so numerous as they once were. Hxpnum lycopodioides, 

 recorded early last century from Rasharkin, and Amblyodon 

 dealbatus from the same place, and also found by Templeton 

 at Holywood and Blaris, seem to be extinct now. 



There is a marked contrast between the Mosses which 

 grow on the basaltic and calcareous rocks of Antrim and 

 the Silurian and granitic rocks of Down. Some species are 

 confined to the basalt and Chalk, such as Hedwi^ia imberbis 

 and Plerogonium gracile (Ballygally Head), Tortula pri?iceps 

 (Clenarm), Anoinodon viticulosus, Hypnum niurale, H. cras- 

 sinervium, and APetzgeria pubesceus. Others, though charac- 

 teristic of these rocks, are not confined to them exclusively 

 — Grimmia conferia var. prui/iosa, Glyphomitriuin Daviesii, 

 and Hypfium Teesdalii. 



Seiigeria Doniana grows on Greensand rocks in Colin 

 Glen ; S. pusilla and S. calcarea on damp Chalk rocks and 

 stones on the Belfast mountains, .'\nother minute moss,
