Een brief uit Australie: een oproep

A number of people are at present engaged in a major revision of the families Rissoidae and Rissoinidae. It is desirable that work in this field be coordinated and to this end I am writing to ask that anyone who is at present working, has worked, or will be working on the classification or biology of these families would get in touch with me. The present workers known to me are: Eugene Coan, Dept. of Geology, Standford University Raio Alto, California who is especially interested in the classification of both families in connection with the publication of the Treatise on Invertebrate Palaeontology.
