Greetings,
My Japanese colleague, Teruaki Nishikawa
(Teruaki at info.human.nagoya-u.ac.jp) is trying to locate material described by
J. W. Spengel around the beginning of this century. If anyone out there can
help him please contact him directly. Even if you don't know specifically
about enteropneusts, where he deposited other 'vermes' could be helpful.
Thanks,
Ed Cutler
