gardens in the vicinity ; but on searching those nearest to the swamp we 

 failed to find the Snowflake in any of them, and Mr. "White has since informed 

 us that the plant is unknown in any of the gardens in the district. Among 

 the mollusca of this marsh we have taken the very rare little land snail 

 Vertigo rrwulinsiana, found elsewhere in Ireland only by the river Barrow ; in 

 England confined to a few of the southern counties ; and on the Continent, 

 like Lfucojnm ae-stivum, widely distributed through the southern and western 

 countries. 



In 1905 a large patch of Lcucojnm atMivum was discovered by !Mr. E. W. 

 Bingham in a bog a few miles from Dungannon, Co. Tyrone. This statement 

 was published in "Additions to Irish Topogi-aphical Botany for 1905" (Irish 

 Naturalist, 1906, p. 60) ; and Mr. Praeger, who has seen the place, informs us 

 that the plant grows in a spot that must have been on the shore of Lough 

 Neagli before it was contracted by the Bann Drainage Works. 



In the Irish Naturalist, 1906, Mr. W. J. C. Tomlinson reports the occur- 

 rence of Leucojnm atstivum in a boggy wood which borders the Lough Neagh 

 shore between the water's edge and the Deer Park wall, about two miles from 

 Antrim town. It was glowing about the centre of the wood, which consists 

 of alder, birch, and willow, with a dense undergrowth. Associated witli the 

 Leucojum were Caltha palmtris, Ranunctdus Flammula, Orchis mascula, and 

 Scilla nutans. There were only a few plants of the Snowflake, which, from 

 Mr. Tomliiison's account, seems to be, in common with many other rare marsh 

 species of Lough Neagh district, failing on account of drainage. 



Ldicojttin acstititm has also been recorded from damp meadows atLisgoole, 

 Co. Fermani^j'h, in Mr. Praeger 's " Flora of the West of Ireland," p. 192. 



As habitats for Lcucojnm acstivum, the Tyrone and Antrim stations, being 

 so far removed from tidal influence, seem at first sight to be abnormal ; but 

 both are in the neighbourhood of Lough Neagh, and we have already shown 

 that the plant is native on the shores of large lakes in Italy and Switzerland. 

 Moreover, we must remember that the flora of Lough Neagh includes 

 several maritime or sub-maritime plants not usually in Ireland found 

 inland — for instance, Viola Curtisii, Spergularia rupestrU, Scirpus marUimus, 

 S. Tahtrnaemontani, &c. 



To sum up the results of our investigations, we have shown that Leucojum 

 aativum is distributed throughout most of the principal river-systems of 

 southern and western Europe ; that in England it has a wide range on the 

 southern rivers under exactly similar conditions ; and that in Ireland it 

 occurs spontaneously and abundantly in at least three of the principal river- 

 systems of the south, with surroundings and associates that in no way differ 

 from those prevailing on the Continent, where its standing as a native has
