Chromodoris elisabethina - spelling

May 17, 2003
From: Roberto Sozzani

Dear Bill,
What's the exact spelling for Chromodoris elisabethina? I found often 'elizabethina', also in your forum sometimes is spelled with 'z' instead of 's'.

A Google search gives lot of results with both names, so I don't know which one is the right one.
Thanks in advance.

Dear Roberto,
I discussed this is an earlier message. On checking back through the Forum I see 3 mispellings have crept through in incoming messages - which I've now corrected. The correct spelling is with an s.

Bergh first used the name Chromodoris elisabethina in 1875, but as it was just in a list with no description it is considered a nomen nudum - 'nude name'. We date the name from 1877, when it is used by Bergh with a description. Russell's very useful Index Nudibranchia (1971) lists the spelling of the name in 1875 as 'elizabethina' but in my copy of Bergh 1875 it is definitely an 's'.

Doris elizabethina Kelaart 1859, is the only possible source of confusion but the description is so poor that we can't be sure what it is - perhaps a dendrodorid.
