Abstract
The type material of Caudofoveata (Aplacophora) deposited in the molluscan collections of the National Museum of Natural History, Smithsonian Institution (USNM), and of the Museum of Comparative Zoology, Harvard University (MCZ), USA, are listed. An extensive analysis of the databases and a curatorial revision of all lots from both collections were made, including an examination of material from Dr. Amelie Scheltema’s personal collections, recently donated and under curation in the MCZ. A total of 2313 specimens from 378 type lots representing 33 nominal species group taxa was found. Of these, 2275 specimens from 358 lots representing 27 species are held in the USNM (22 holotypes, 2 syntypes and 334 paratypes) and 38 specimens from 20 lots representing 7 species are in the MCZ (5 syntypes, 9 paratypes, 3 paralectotypes, 3 doubtful paralectotypes). Some taxonomical notes about these species and their type-materials are provided.
