What is the star system?
The star system calculates the number of pieces that were handled by Conchology, Inc. in the last 21 years:
| 0 – 5 pieces | 6 stars |
|
| 6 – 10 pieces | 5 stars |
|
| 11 - 25 pieces | 4 stars | |
| 26 - 75 pieces | 3 stars | |
| 76 - 150 pieces | 2 stars | |
| > 150 pieces | 1 star | |
We want to point out that the star system is only very reliable for PHILIPPINE shells only, as we handle very few foreign shells in general. As time goes, the system will become more and more performant.

CALLOCHITONIDAE
Until recently this was a subfamily in the ISCHNOCHITONIDAE, but now considered a valid separate family. There are five genera, of which Callochiton is the biggest with a large number of species. Callochiton have a wde girdle with elonate spines and scales. They have a worldwide range, but the best known European species is definitely the septemvalvis.
Eudoxochiton live in Australia and New Zealand, but there are only two species.
