"corpii" as plural of "corpus"

[James Harbeck]

Yet another manifestation of the (it seems to me) rather common
belief that the plural of any -us is an -ii (not an -i, as it would
often be; it seems that the more marked -ii, as in radii, has stuck
in many people's heads as more right). I've run across the -ii quite
a few times, though I've never noted corpii before (korpi, yes, which
is Finnish for "forest", but not corpii).
