On the desmostylid skeletons.

–In Japanese; Engl. summ.
Although the Izumi skeleton is referred to on p. 20 as the "neotype" of Cornwallius (i.e., Paleoparadoxia) tabatai, a disclaimer at the end of the text on p. 21 states that the article is a "popular essay" written at the request of Dr. Yukio Ozaki, and "not an original article" (fide Dr. Naoki Kohno, in litt., 4 April 2006). Accordingly, under Art. 8.2 of the 1999 International Code of Zoological Nomenclature, this work is not deemed "published" for nomenclatural purposes, and this neotype designation takes its correct date from Shikama (1966c: 155).
