Original source
Dawson (1868): 302, text-fig. 102a–c; originally as “ Hardingi ”.

Type material
Dawson had two specimens. Beede (1911) selected the specimen figured on fig. 102a of Dawson (1868) as the “type” (constituting a valid lectotype designation). He separated the other specimen as a new species: dawsoni. Both species are stored together at the Redpath Museum of McGill University, Montreal, Canada, under coll. no. 2820 (coll. Dawson and Hartt).
