Yes, I have to say, it does look VERY ampullaria X ventricosa... Since ventricosa's lids are usually VERY close to the peristome, I would think that the position the other pitcher's lid is in is about in between that of ventricosa, and ampullaria... With a ventrata, I think that It would be reclined a bit further... not only is the bottom of the pitcher ventricose, but the top is too, which makes me think that there isnt any alata in it...
