Additions and corrections to Land Snails of British Columbia
This page serves two purposes:
- To correct obvious errors that crept into the book undetected; and
- To offer new information (new distributional data, additional species and important references) that have arisen since the book went to press.
Introduction (p. 4)
... Pulmonata is ranked as a subclass, but many recent classification schemes ...
Names of Snails and Slugs (p. 20)
... as in Cryptomastix germana ...

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. Found on the Liard Plain in northern BC in 2004. Selected references: Dall, 1905; Gusarov, 1999; Likharev and Rammel'meier 1962; Pilsbry 1948.
Lauria cylindracea (p. 43)
Figure: Both left and right figures are adult snails. The right snail is only a shorter form, common in all populations.
Etymology (p. 44): According to Kennard & Woodword (Synonymy of the British Non-marine Mollusca, 1926), Lauria was probably named after Laura Gray, a niece of John Edward Gray.
Planogyra clappi (p. 44)
The body is white, rather translucent, with the dorsal head and tentacles darker (grey).
Pupilla hebes (p.52)
Distribution. Recently found (2004) from several additional sites near Good Hope Lake and north of Atlin in northwestern B.C.
Columella columella (p.54)
The author should be written as "G. von Martens" to differentiate from "E. von Martens" elsewhere.
Nearctula species (p. 57)
Synonym: ... not Newcomb [no final 'e'].
Vertigo andrusiana (p. 59)
Distribution. Correct to "San Bernardino".
Vertigo arthuri (p.54)
The author should be written as "E. von Martens" to differentiate from "G. von Martens" elsewhere.
Vertigo modesta (p. 65)
Synonyms. "?Pupa corpulenta parietalis Ancey, 1887" should be "1888" (described in the issue of The Nautilus published on 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)
Comparison: ... both has a larger umbilicus and
Distribution. Recently found (2004) at Skidegate, Queen Charlotte Islands.
Zonitoides arboreus (p. 98)
The year of publication for this species is 1817, not 1816, as usually written.
Daudebardiidae (p. 101)
Correct spelling of "Daudebariidae" to "Dardebardiidae" in heading. Or rather, use the family name Oxychilidae.
Vitrina pellucida (p. 109)
Genitalia: remove Roth & Lindberg 1981 reference; they did not describe or illustrate this species' genitalia. To avoid confusion 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 another 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).
Hygromiidae, Trochulus, and Trochulus striolatus should be added
Recently discovered in B.C.
