Conus
druidi (Olsson, 1967)
As first reported by Olsson
(1967), the holotype of C. druidi was discovered in an old collection at
the USNM supposedly from La Belle, Hendry County, Florida (USNM station 22445).
Exposures at La Belle are primarily of the Caloosahatchee Formation, not the
Pinecrest Beds of the Tamiami Formation, as suggested by Olsson (1967). Because
no other unambiguous information suggests that this species occurs in the
Caloosahatchee Formation, it is likely that Olsson’s locality information for
the holotype of C. druidi is incorrect (2).
The holotype and other observed
specimens of C. druidi appear to agree fully in shell characters
(including color pattern) with Dominican Republic specimens, including the
lectotype (BMNH 83961) and other specimens of C. haytensis in the
collections of the PRI. Th is association was also made by Olsson (1967: 21)
when he described the species, stating that the “shape of the cone and its
fluorescent pattern places it amongst a group of fossil species such as:
Conus
haytensis G. B. Sowerby II, from the Miocene [Pliocene] of Santo
Domingo
Conus molis Brown & Pilsbry (1911) from the Gatun Miocene [Pliocene] of the
Canal Zone, Panama, Costa Rica, and Columbia.” (2).
