some time. The dredging also resulted in the bring¬ 
ing to dry land of the three shells, Planorbis albus 
and contortus and LymncEa peregra, and also the 
eggs of these snails, which one of the party took with 
him to propagate. Greater results might have been 
produced by the dredging, bnt the call that “time 
’ was up ” put an end to work, and gathering the last 
plant of the day, the “ Moonwort ” fern, BotrycMum 
lunaria, on the pasture to the south of the Loch, we 
returned post haste to Almondbank Station. On a 
cursory examination of the various objects got during 
the excursion, I find there were thirteen shells, 
upwards of twenty species of Lepidoptera, fourteen 
species of Hemiptera or Bugs ; and of Coleoptera or 
Beetles, upwards of seventy species ; of plants, ex¬ 
cluding the commonest species got everywhere, we 
gathered upwards of forty.

White) was read on 
An Addition to the Perthshire List oe Land 
AND Freshwater Mollusca. 
On Saturday, May 21st, I had the pleasure of 
finding (conjointly with Mr Bruce) Helix lamellata, 
on Birnam Hill. This beautiful little shell (of which 
I present specimens to the museum) is perhaps the 
most boreal species of terrestrial mollusk that inhabits 
Britain. According to Mr Jeffreys its range in Bri¬ 
tain is the north of England and Angiesea, the north 
and north-west of Scotland, and Ireland. The only 
exotic localities in which it has as yet been detected 
are North Germany and Sweden. After, for the first 
time, making acquaintance with Helix lamellata in 
Boss-shire, in 1868, I had a conviction that it ought 
to be found in the neighbourhood of Dunkeld—either 
on Birnam or in some of the glens (such as Beichip) 
lying between Dunkeld and Blairgowrie—but till the 
other day I had not the opportunity of searching for 
it in that district ; and though some shells have been 
gathered on Birnam at various times. Helix lamellata 
does not appear to have been hitherto found there, or
