Hi Jena and Camille, thanks a lot for the info!
now I must admit I feel a bit stupid... I have Holst's book, and it was the first place I checked for some information. I could not find it in the text, and therefore did not check the plates... After your message (Gena), I checked again, and no text, but the photo on plate 52 is indeed there (very nice Cstm
) it was weird... so, I checked again.. nope nothing there...
and then I realized my copy of the book is missing pages 189 - 190, and it goes from Ctsm moorei to Ctsm naso
