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.

[25° 2' N, -77° 17' W]
"on an isolated grass plot"
Type Material:
Lectotype, USNM 359502
Additional Records:
MolluscaBase Information:
No MolluscaBase Information Found.
Remarks:
Following Article 32.5.2.4 (ICZN, 1999:40) the hyphen is removed from varia-thorndikei and the taxon becomes variathorndikei. A label accompanying the lectotype stated "on an isolated grass plot, now extinct. 1915." Gould and Woodruff (1986:478) regarded this taxon to be a synonym of Cerion gubernatorium (Crosse, 1869), although it is unlikely that they had seen specimens.
