-i or -ii? (ICZN)

Dear Schlemmermeyer & Wuster,

The case of (zoological) patronyms were discussed extensively on Taxacom
some time ago.

It is always difficult to be sure when an author made a misspelling or an
intentional change. Like the quote above: did Schlemmermeyer really leave
out the "s" in "tchudii" intentionally - or simply as a lapsus?? The exact
circumstances are crucial. What exactly did the author write; how many times
does the name appear, etc.

If the (zoological) species is explicitly "named after Mr Tschud", there
would be an argument for an emendation to "tschudii". Still, the author
could have left out the s for some reason, like a different translitteration
if the name was originally in cyrillic, or for the sake of euphony, etc.

The ending "-ii" could result from a Latinization of Tschud --> Tschudius,
and I would leave the ending unchanged.

>>If an animal is named after a gentleman with a name ending in -i (e.g.,
>>Tschudi), then the complete species name presumably should end in -ii
>>(i.e., tschudii). Would a name failing to conform to this require

>>require no action?

Article 33(d) deals with subsequent spellings. Your question relates to the
original spelling, whether correct or incorrect.

The spelling "tschudi" would be grammatically incorrect (Article 31a ii).
That of "tschudii" is correct and emendation would be mandatory.
