Additions and corrections to Land Snails of British Columbia
This page serves two purposes:
- To correct obvious errors that crept into the manuscript undetected; and
- To offer new information (new distributional data, additional species and important references) that have arisen since the book went to press.
I welcome suggestions, corrections and additions.
History of Terrestrial Malacology in B.C. (p. 22). For more information on the life of John Keast Lord, see:
Baker, D.B. 2002. John Keast Lord: Materials for a Life. Leiden: Backhuys Publishers. viii + 65 pages.
Checklist (p. 24). Genus Lauria J.E. Gray in Turton, 1830 1840.
Key to Snails (p. 31):
Couplet 9b: add Novisuccinea.
Couplet 17: occasionally Allogona ptychophora do have a very low parietal denticle or callus and will key out wrongly as Cryptomastix.
Family Succineidae (p. 39). First sentence should read: "Shells of these mostly wetland snails ..."
Add to the family Succineidae (p. 39) and to the Checklist (p. 24) the following species:
Novisuccinea strigata (Pfeiffer, 1855)
Synonym. Succinea rotundata Sowerby, 1862; S. chrysis Westerlund, 1883; S. annexa Westerlund, 1883; S. lineata W.G. Binney, 1885.
Recently collected (2004) from the Liard Plain in northern B.C.
Selected references: Dall, 1905; Likharev and Rammel'meier 1962; Pilsbry 1948.
Lauria cylindracea (p. 43). Both left and right figures are adult snails. The right snail is just a shorter form.
Pupilla hebes (p.52). Distribution. Recently found (2004) from several additional sites near Good Hope Lake and north of Atlin in northwestern B.C.
Vertigo andrusiana (p. 59), Distribution. Correct to "San Bernardino".
Vertigo modesta (p. 65), Synonyms. "?Pupa corpulenta parietalis Ancey, 1887" should be "1888" (described in the issue of The Nautilus published 23 January 1888).
Distribution (p. 66): add Kamchatka and the Kurile Islands. Also Europe, if Vertigo arctica is treated as a synonym.
Anguispira kochi (p. 79). "Anguispira kochi (Pfeiffer, 1821)" should be "1846" (and again, in the synonyms).
Vitrea contracta (p. 93). Distribution. Recently found (2004) at Skidegate, Queen Charlotte Islands.
Daudebardiidae (p. 101). Correct spelling of "Daudebariidae" to "Dardebardiidae" in heading.
Vitrina pellucida (p. 109). Genitalia: remove Roth & Lindberg 1981 reference; they did not describe or illustrate this species' genitalia. Clarify the final paragraph of Description: " It differs from the related V. angelicae ... by having much of the penis and vas deferens enclosed together in a sheath of protective tissue ...".
Vitrina exilis Morelet, 1861, from northeast Asia but also identified in older literature from Alaska, is a synonym according to Likharev (1963, On the fauna of the terrestrial molluscs in the Kamtchatkan region. Trudy Kamchatskoj Kompleksnoj Ekspeditsii, p. 65-81, in L.A. Portenko (Editor), Fauna Kamchatskoj Oblasti).
Hemphillia camelus (p. 137). Correct distribution to read "Southeast BC, Alberta and Idaho." (Not Montana.) Also, remove "Kamloops". Under Selected References, remove Frest & Johannes (2001) reference.
Hemphillia glandulosa (p. 139). Change "Bland & W.G. Binney 1873" to "... 1872".
Arion hortensis (p. 148). This species has now been confirmed for British Columbia (H. Reise, pers. comm.).
Allogona ptychophora (p. 148). Description: Aperture usually lacks a parietal denticle, but occasonally shells with a low parietal denticle, or just a small white callus, do occur. Watch out using the Key to Snails, p. 31!
Key to species of Cryptomastix (p. 151). Couplet 1b should read "Shell width more than 9 mm ...".
Cryptomastix mullani (p. 152). Description: read 6 whorls not 16!
Cepaea nemoralis (p. 161). Etymology: Cepaea from κηπαιος (cepaios), Greek, "pertaining to a garden" according to Pilsbry (1939) and Kennard & Woodward (1926).
Photo credits (p. 184). Two names of contributing photographers were unfortunately misspelled: I once again thank Drs. Vollrath Wiese and John Hutchinson for the use of their photos, and apologize for these errors.
