I know, but the name of Thieme had just to mean a serie of studies in a same
direction, not only Thieme's work of 1953. Also the list of the animals was
uncomplete at all.

About the *laks problem, I don't think the objections I read in those years
to Thieme's central ideas were really convincing.

Best regards.
