Oxychilus draparnaudi, Ottawa, 2016.
The somewhat unimaginatively named Dark-bodied Glass-snail — “Inky Blue Glass-snail” might have been better — is one of three species of terrestrial snail belonging to the genus Oxychilus in Canada. (Oxychilus alliarius and O. cellarius are the others.) Among these three species, this one is perhaps the most widely distributed, having been reported from Atlantic and Central Canada, as well as British Columbia. Many unpublished records exist in collections.
This photo was taken in an urban “wasteland” ravine in Ottawa in 2016.
Previous photos of this species are here and here.
Well almost …
Last month, Mike Oldham, Fred Schueler, and I published our paper on Patera appressa in Ontario. This species had been on our radar for some time. Fred discovered it for the first time in Ontario (and Canada) in the spring of 1994. Since that time, all of us have gone back to sites; I was there last September (2014).
Patera appressa from along the Trent River, Trenton, City of Quinte West, Hastings County, Ontario, Canada; NBM 009026; maximum diameter (width), 14.3 mm.
