have one important correction, and a few other miscellaneous ones. The modern chimaeroid jaw developmental analysis was done by Eileen D. Grogan, but attributed to Dominique Didier (Dagit) in the volume. Also note that the pectoral fin of Chondrenchelys problematicaillustrated in Fig 33 A is that of a male; the females have pectoral endoskeletons essentially identical to Harpagofututor volsellorhinus(Fig. 33 B). Finally, "Similharriotta dabasinskas" is a junior synonym for the cladodont elasmobranch Bandringa, although I do not know which species. It is not a holocephalan. It has cladodont teeth.

Ian discovered thelodonts in the Lower Devonian of Reefton this year and at the Edinburgh VPCA meeting in September 1999 spoke about the various microassemblages and the difficulties of arresting them from the clutches of theSouth Island temperate rainforest.

John attended the SVPCA meeting in Edinburgh and gave an interesting overview of Devonian sharks from the Malvinokaffric province of Gondwana featuring a little shark braincase from Brazil which he and Eric Anderson are studying.

I have finished the biostratigraphic paper on Severnaya Zemlya vertebrates (version in Russian for Novosibirsk volume) with Valya Talimaa, and the taxonomical work on the thelodont species now in press with Geodiversitas should be in Paris. A new Canadian Arctic thelodont Boothialepisis also described (in Paleontology). Now we are working on the thelodont chapter for the new edition of Obruchev"s Osnovi Paleontologi "Fundamentals of Paleontobgy" Agnatha & Fish volume being produced by PIN and the Russian Academy of Science.
