Terrestrial molluscs of the Province of Newfoundland and Labrador, Canada. Part 1: Boettgerillidae

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within an appendix, to provide a national perspective for the Newfoundland and Labrador record, are 13 previously unpublished B. pallens records from British Columbia, Canada.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.
