Dear Leon,
Thanks for your rapid response. Apart from Bob Burn's sketches of a living animal in Burn & Thompson, 1998, your photos are the only information I have on the nature of the animal of this enigmatic species, which was described on the basis of an empty shell.
I am posting a message today [#23242] on a very similarly looking species from the Andaman Sea. It's colour is very similar but the shell is not as exposed as in N. exigua and the head looks a little different in shape. Perhaps they are the same, but without any anatomical information I think it is best to leave them apart until we can comare them anatomically.
