Finally and at last, another specimen of this little beauty, which I first observed last November (https://www.inaturalist.org/observations/18597683). These are the only specimens of this species I have ever seen anywhere!

Shell 7.4 mm long, found on the underside of a low intertidal boulder, along with two small Conualevia alba and a good size Stenoplax conspicua (see 3rd image, which shows the clam as I found it after turning the rock). 4th image shows the cobble field where I found this specimen, as well as the two last November. The last two images are of this specimen relaxed in MgCl2.
