The latin names Baster used aren't used any more because he didn't use Linnean binairy names.

A hunderd year after the publications of the books of Baster and Slabber the Dutch marine biologist Maitland (1876) made an attempt to identify their species. He published his list in: Determinatie der dieren, beschreven en afgebeeld in de werken van Job Baster en Martinus Slabber. Tijdschr. ned. dierk. Vereen., (1) 2: 7-15. In later years various authors corrected Maitland list.

On this site the names given by Baster and Maitland, the corrections and the current names are presented under the illustations.

Literature was studied for recent identifications. Where no recent data were found Godfried van Moorsel and I checked ourselves and asked specialists to help identify Basters species. Specialists who helped identifying species are named at the appropriate places.
Current names for marine species were checked at WoRMS.
