Recently Ellis L. Yochelson visited the Shanghai Museum of Natural History and saw the illustrated specimen of Dentalium (A.) acumen from the lower Carboniferous of Guizhou Province, China. He pointed out that the straight shell of Dentalium (Antalis) acumen (Koninck) which was described by Wang (1987) is an orthoconic cephalopod. The anterior part of the shell is crushed, as is common on the living chamber of those orthocones which preserve it. Examination of the early part of the shell showed that it was broken along a curved surface; that is, it broke along a septal wall. By wetting this area, it was possible to see the outline of a central siphuncle at this septum. Thus, it remains true that until now, no scaphopod has been recorded in Chinese Paleozoic beds.
