vera and itxmra. Unlike the last, this 

 species never deserts the open country, 

 and occui's most frequently in districts 

 which contain old native woods or rough 

 ground that has never been under 

 cultivation. 



It has recently been collected on Clare 

 Island ("West Mayo), by Mr. H. Wallis 

 Kew, this being the first record outside 

 the mainland.

Generally distributed throughout the 

 mainland, and found on Lambay, in 

 Dublin, and on llathlin, in Antrim. 

 There are no records, however, for any 

 of the western islands ; and along the 

 west coast it is exceedingly local. 

 Usually inhabits gardens, hot-houses, 

 churchyards, cellars, and even larders 

 and sculleries, where it hides in cre- 

 vices during the day, and only makes 

 its appearance after dark. It is, how- 

 ever, also known to occur in some of 

 the old native woods. The cracks 

 into which this slug can crawl are 

 amazingly small. j!s"o variation of any 

 real importance has been noted, but 

 occasionally lighter or darker specimens 

 are met with.

Generally distributed and usually 

 common, but perhaps most abundant in 

 the mountainous districts of the west 

 coast and on the western islands, from 

 nearly all of which it has been recorded, 

 as well as from I.ambay in Dublin, and 

 llathlin in Antrim. As its name implies, 

 it is regarded generally as a tree-slug, 

 and in many cases this is undoubtedly 

 correct ; but the wholesale destruction 

 of our woodland areas has in no way 

 iliminished its distribution. Great varia- 

 tion is shown in the colour and marking 

 of this slug, and many beautifully 

 .striped and spotted foiins are to be 

 found ; these are particularly common 

 in the west. A unicolourous mountain 

 form, Ldmost black, has been recorded 

 from high altitudes (over 2000 feet) 

 in Kerry, Mayo, and Down. The alti- 

 tudinal range of Limax arbornm is very 

 great ; and from sea-level it occurs up 

 to a height of 3000 feet in the Reeks, 

 South Kerry, at which altitude uni- 

 formly black specimens were first
