Calliostoma anseeuwi - 1052040

A SERIOUSLY EXCITING SPECIES, AND A SHELL THAT MADE OUR DAY

Sorting out the rough dredged gravel from Pangan-an, near Olango Island, from a dredge that came up from the deepest parts of the channel: 400 m. The almost intact aperture of this delicate Calliostoma is something like a miracle.

The Calliostoma anseeuwi is a valuable species: few are known, and this is the third shell we got and the first one we can offer for sale as such. We had to wait a staggering 6 years since the description before we got this anseeuwi, which we think is the second adult one next to the holotype of 23 mm.

The shell is named after Patrick Anseeuw, co-author of the Pleurotomaria book, long time friend of your present author. Patrick is a lifetime shell enthusiast and as such member for decades of the Belgian conchological societies (Brussels and Antwerp so to speak). But his main passion has always been Pleurotomariidae, and, likely because of their Pleuro-resembling shape, Calliostoma have always been one of his favorite groups in the phylum. From where naming a Calliostoma after him was truly appropriate.

Estimation: Described in Visaya in 2006 and virtually absent from private collections. We therefore think the value of this specimen is fairly high and estimate the shell between 250 and 500 euro, but more so close to 500 than to 250. Under strong light and with the microscope one can see three microholes - they look like small dust. This is an indication that the shell was dredged dead, despite the fresh colors. we can repair these micro-defects on demand before sending the shell.
