Thanks Matt for pointing out the error. I think I have put in the correct instructions to change the name but it is the first time so will jusy wait to see what happens. May come back for some pointers if I have got it wrong if you do not mind helping out.
The spider encyclopedia is shameful, really. I'd volunteer to do something about it, except that I have my own (competing) Gallery and not enough time to keep that up to date. Thanks for your efforts with M. vatia.
