The present paper deals with the material of the Brachyura of the tribes Dromiacea, Oxystomata, and Oxyrhyncha obtained by the Snellius Expedition and placed at my disposal through the kindness of Prof. Dr. H. Boschma. At the same time it contains some remarks on the material of the Rijksmuseuin van Xatuurlijke Historic at Leiden.
The present paper contains the results of a study of the Paguridae of the Snellius Expedition, with the exception of the larger part of the Pagurinae, which until now I was unable to identify with sufficient accuracy.
