ICZN Naming Rules Help

[goodyearkl]

Hi, I was wondering if you could help me with this problem?

Here is what I have ruled out ( I have the first one):

The example on the ICZN website states that:
The lion was originally described by Linnaeus as Felis leo but over time knowledge of the cat family developed and the genus Felis was split up; the lion was placed the new genus Panthera and so the name is now Panthera leo (Linnaeus, 1758)

I am assuming that the brackets mean a name change?

I want to say Ornithorhynchus anatinus (Shaw) is the second answer but the date is not there.

Any advice?

Thanks!
