Additional notes.—(1) In Pennant’s “Tour in Scotland,” fourth 
edition, vol. ii, p. 190, that author, in referring to his visit to 
Ailsa Craig, says, inter alia—‘ Three reptiles appeared here very 
unexpectedly, the naked black snail, the common and the striped 
shell snail: not volunteer inhabitants, but probably brought in 
the salads of some visitants from the neighbouring shores.” 
(2) My friend, Mr. James Steel, informs me that he observed 
the Wood Tiger Moth (?) Chelonia plantaginis, Linn., on one of 
his visits to Ailsa Craig, which adds still another to our list of 
invertebrates. 
(3) I find, on looking through some literature relating to the 
West of Scotland, that two other and former members of this 
Society have taken a considerable interest in Ailsa Craig and its 
natural history, viz., Mr. Robert Gray, who studied its bird life, and 
Mr. Newton MacCartney, who examined its geological structure, 
and also in 1864 (according to Dr. Bryce) made a careful investi- 
gation of its plants, but apparently no systematic study of its 
invertebrates has hitherto been taken in hand, yet the study of 
these might prove to be as interesting as the others. 
* At the meeting of the Society on 25th January, 1898, Mr. Anderson 
Fergusson exhibited the following additional species of Coleoptera from 
Ailsa Craig, viz., Byrrhus pilula, Linn., Otiorhynchus blandus, Gyll., and 
O. rugifrons; Gyll.
