HANTKEN'S OEUVRE /. SZABÓ, Professor of Geology at the Royal Hungarian University of Sciences went to a study trip to N America in 1882. Here he also visited Philadelphia where he met the Professor of Palaeontology of the Academy of Natural Sciences, A. HEILPRIN who accidentally was also of Hungarian origin. Among others, A. HEILPRIN described the first Nummulites of the U.S. from Florida as N. willcoxi (1882). J. SZABÓ also received rock samples from A. HEILPRIN from the Florida locality, whose fauna was determined upon the invitation of /. SZABÓ by M. HANTKEN (1886). Besides N. willcoxi M

. HANTKEN could also separate another Nummulites that he described as a new species and named N. heilprini after the American scientist. By the describing of this new species, together with N. floridensis described by A. HEILPRIN in the meantime (1884) three species of Nummulites became known from Florida. During his palaeontological investigations M. HANTKEN dealt mostly with the Upper EoceneUpper Oligocène marl-, calcareous marl and clay sequences of the central Hungarian Mountain Range of great extension that are rich in small Foraminifera. His results were published in three major studies ( 1868, 1872, 1875) of which the most important is his work of 1875 that is an important contribution to the investigations of Palaeogene stratigraphy and micropalaeontology that is still essential for experts. M. HANTKEN's work had also a great impact even in the United States among the micropalaeontologists, and here the name of /. A. CUSHMAN may be mentioned in the first place concerning M. HANTKEN's investigations of small Foraminifera. CUSHMAN spent a long time studying HANTKEN's still valid results in the field of micropalaeontology. CUSHMAN, when found a taxon similar to the Siderolina kochi HANTKEN (in Cocoa, Alabama), on the genus level he introduced it as new taxon. In the honour of M. HANTKEN he denominated it as Hantkenina (1924). Later family and subfamily were also formed for the Hantkenina species in order to classify them in higher systematic order (1927). Even at a later period CUSHMAN still greatly respected M. HANTKEN due to the fact that Professor L. MAJZON sent him a large amount of samples from HANTKEN's localities in the 1930s. M. HANTKEN's international reputation may have started about in this period. It is confirmed by the fact that in case of several genera the name hantkeni is also included. The study includes all the taxa denominated in the honour of M. HANTKEN. The list is probably incomplete and that is the reason why the author would greatly appreciate to receive further additions by the American colleagues.
