| Abstract |
The type specimens of fossil “Architectibranchia” and Cephalaspidea (Mollusca: Heterobranchia) deposited in the Academy of Natural Sciences of Philadelphia, USA, are listed herein. The collection includes types of circa 60 species, from the families: Acteonellidae, Acteonidae, Bullidae, Cylichnidae, Haminoeidae, Philinidae, Retusidae, Rhizoridae, Ringiculidae and Scaphandridae. The catalogue is presented in systematic order, with information on the original description, type locality, type stratum and age, catalog number in the collection, and current taxonomic status. Further taxonomic notes are offered when pertinent. Several species are illustrated here for first time. The new combinations Roxania hornii (Gabb, 1864) and Volvulella minutissima (Gabb, 1860) are proposed. Some species that have previously been assigned to Acteonidae are revised here, resulting in the following new combinations: Odostomia milium (Lea, 1846), Chrysallida sculpta (Lea, 1846) and Pyrgulina angulata (Lea, 1846). The list of taxa is also presented in other arrangements (alphabetically by specific epithets and by authorship and date) to facilitate locating information. |
