Dispersed scolecodonts from Cainozoic strata of Jamaica Naturalis
Germeraad, J.H..
Scolecodonts found in Cainozoic palynological and palaeontological samples from Jamaica are compared with dispersed scolecodonts from Tertiary strata in France. The problem of delimiting species and genera is discussed in view of the variability observed in Recent polychaete annelids and of the dissimilar populations found in the two regions.

A computer-based registration system for geological collections Naturalis
Germeraad, J.H.; Freudenthal, M.; Boogaard, M. van den; Arps, C.E.S..
The new computer-based registration system, a project of the National Museum of Geology and Mineralogy in the Netherlands, will considerably increase the accessibility of the Museum collection. This greater access is realized by computerisation of the data in great detail, so that an almost unlimited number of operations to select and sort the data is possible. A flexible design of annotating information, mainly in plain words, saves considerable time. The fast mechanical data processing permits the efficient preparation of catalogues which contain selected information about the geological collection; as an additional benefit labels may be produced at low costs. The RGM system disposes of the burden of classical registration books and card-indexes, without...
