It is evident from the above records that Leach must have 
done a considerable amount of field work in the south of 
Ireland prior to 1820. Of the above references those to Ena 
obscura and Chilotrcma lapicida are the most interesting. 
The record of the latter species is not, however, given on 
the personal authority of Dr. Leach, and is, therefore, of 
little value, as Thompson^ could not satisfy himself that 
C. lapicida had ever been found in Ireland as a native. No 
Irish specimens have been forthcoming since the publication 
of Thompson's " Catalogue " in 1840, indeed in vol. iv. of his 
" Natural Histor}^ of Ireland," the reference to C. lapicida, 
referred to in footnote, is omitted. It would seem, therefore, 
that the belief that this species lived in Ireland was not well 
founded.'- It must be remembered, however, that in many 
of its habitats in England, C. lapicida is not now so plentiful 
as in former times, while in not a few localities it has become 
extinct. 
Dr. Leach's record of Ena obscura from near Killarney 
can scarcely be doubted, even though this shell has not been 
reported from this district within recent years. It would be 
wise, however, before adding the name E, obscura to the 
fauna of North Kerry to have the record verified.
