The family Boettgerillidae, represented by the Eurasian slug Boettgerilla pallens
Simroth, 1912, is first recorded for Newfoundland and Labrador, Canada—a range extension
of almost exactly 5000 km within the Americas. Compiled, within an appendix, to provide
a national perspective for the Newfoundland and Labrador record, are 13 previously unpublished
B. pallens records from British Columbia, Canada. Incidentally recorded is the second
eastern Canadian outdoor occurrence of the European slug Deroceras invadens. This
paper is the first in a series that will treat all of the terrestrial molluscs of
Newfoundland and Labrador.
