Why do Don and Ra talk about a lenticular galaxy when our galaxy is spiral?

Anyway it's still strange, although my best guess now is that Ra was using lenticular as an adjective which Don then picked up.

I think I remember Ra choosing all terminology including scientific terms with great discretion and care, often choosing terms in ways we would not. The point is that I doubt the term lenticular was an accident but could possibly have been. I suspect Ra was simply referring to the cohesion and plane without discriminating between spiral and lenticular because he felt it wasn't necessary.
