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.

Cerion iostomum Pfeiffer. Pl. XI, fig. 14.
This species has not been figured. It was described from the south coast of Cuba living among Prickly Pears. Subsequently it was reported from Turk's Island and Great Inagua (see Bland, Ann. Lye. Nat. Rist., N. Y., XI, p. 85), but having examined specimens from these localities, so labelled by Bland, we find them to be totally distinct species, having little save the purplish-brown color of the mouth, in common with the true Pupa iostoma of Pfeiffer's first description.
The specimen shown in our figure answers to the description of Pfeiffer in all respects save that the median whorls are only obsoletely ribbed, hardly "distanter plicato-costata" -more like the" var. β." The post-nepionic whorls of the cone are "conferte costulatum;" the cone itself "corneo-marmoratum", suture conspicuously "exsertomarginata," and the corrugation of last whorl and color of aperture ("intus violacea") are likewise in agreement. The specimen figured is 2 mm. shorter than Pfeiffer's. Alt. 30, diam. 12; alt. of aperture 12 mm.
Pfeiffer's type measured, alt. 32, diam. 12; alt. of aperture 13 mm." (Pilsbry & Vanatta, 1896:329).
