Wondering if there's a particular name for this morphology?

Well, assuming it's a single galaxy, there seems to be a loose spiral arm at top right, curving to the left, but otherwise no separation of the extensive hazy matter into spiral arms at all. So I was wondering whether there was a descriptive name in common use for galaxies of this shape and appearance.

I would also like clarification on this. Take AGZ0002LFW:

The most evident part is elliptical, but it also could be interpreted as a bar with very faint spiral arms coming off of it. Now, the question the classification routine asks is, is it smooth without any sign of a disk? Since that would seem to be the case, I've been classifying these as smooth/inbetween. But I'm not sure about it and it's bugging me.

My opinion : feature-bar-spiral-budge noticeable-nothing odd
Nice barred spiral (with faint arms it's true..) :)
